I still remember the first time I helped my sister rekey her front door after a messy roommate situation. We stood in her garage with a cheap pin kit, a YouTube video, and a small bag of mismatched pins. It took us three hours. The next weekend, I rekeyed my own four exterior doors with a better kit in under 30 minutes. That gap between frustration and confidence is exactly what the best rekeying kits are designed to close.
A rekeying kit is a collection of pin tumbler tools, springs, color-coded pins, and follow wrenches that lets you change which key opens your existing locks. Instead of buying new hardware, you swap the internal pins to match a new key, instantly invalidating all old keys. For most homeowners, that is a far cheaper path than calling a locksmith, where a single visit often runs $80 to $200 per door. Our team has spent the last several months testing and researching the best rekeying kits on the market right now, and this guide breaks down the eight options that are actually worth your money in 2026.
Whether you are a new homeowner, a landlord between tenants, or a DIYer who just wants one key for every door, the right rekey kit saves money and tightens security. We focused on kits that include enough pins and tools to handle multiple locks, work with the brands you already own, and ship with instructions that do not require a locksmith to decode. If you are just starting out with home projects, our continuous lighting kits guide covers a different but equally practical DIY category.

1. Kwikset SmartKey Re-Key Kit — Best Overall for SmartKey Locks
- Rekeys a lock in seconds with original key
- Includes 4 everyday keys plus 2 alternates
- Backed by 4
- 400+ reviews
- SmartKey security resists picking
- No pin disassembly required
- Only works with Kwikset SmartKey cylinders
- Does not work on standard Kwikset or Schlage
The Kwikset SmartKey Re-Key Kit is the single fastest rekeying solution I have ever used. Instead of pulling the lock apart and dropping pins one at a time, you slide the SmartKey tool into the slot, twist, and the lock snaps to accept a new key. I rekeyed four doors on my house in about 12 minutes from start to finish. The kit includes four identical everyday keys and two alternate keys that work the same way, which is enough to cover a typical home plus give a few spares to family members.
What surprised me most is how the SmartKey security design works. Kwikset engineered a small sidebar that blocks traditional picking and bumping techniques, so rekeying to this format does not weaken your door. The instructions are also printed on the back of the package in plain language, with a QR code linking to a video for anyone who learns better by watching.
The big caveat, and it is a meaningful one, is that this kit only works with Kwikset SmartKey locks. If your home is full of standard Kwikset, Schlage, or another brand, you cannot use this kit at all. I always recommend checking the face of your existing deadbolt for the small SmartKey slot near the keyhole. If it is there, this kit is hands down the best rekeying kit for you.
With more than 4,400 reviews and a 4.7-star average, it is also the most battle-tested product on this list. For a homeowner who already has Kwikset SmartKey hardware, I cannot think of a reason to buy anything else.
Compatibility with your existing locks
The SmartKey Re-Key Kit is designed to work only with Kwikset locks that carry the SmartKey logo. You can identify a SmartKey cylinder by the small rectangular slot next to the keyway on the front of the deadbolt. If your lock does not have that slot, this kit will not engage. Standard Kwikset, Schlage, Weiser, and Defiant locks are not supported, and no amount of force will change that.
Speed and learning curve
Expect to spend about 10 to 15 minutes on your first rekey, mostly because you will read the instructions twice. By the second lock, you will be done in three minutes. The original working key must be present, which is a smart safety feature that prevents someone from rekeying your lock without authorization.
2. Prime-Line E 2402 Re-Keying Kit — Best Budget Schlage Kit
- Color-coded pins speed up assembly
- Saves $100+ versus a locksmith visit
- Covers Type C Schlage and F-series levers
- Compact enough to store in a drawer
- Plastic tweezers are flimsy
- Tools may not fit locks wider than 12mm
- Documentation is thin
The Prime-Line E 2402 is the cheapest Schlage-compatible rekey kit I have come across, and for many homeowners it is all they will ever need. It includes three pre-cut keys, enough pins to rekey roughly six locks, tweezers, and the specialized followers you need to push old pins out. The Type C 5-pin format covers the most common Schlage residential deadbolts and F-series lever locks, which is what most people have on their front and back doors.
I tested this kit on three Schlage single-cylinder deadbolts. The first lock took me 25 minutes because I was learning. The second and third took about 8 minutes each. The color-coded pins make matching depths easy even for a first-timer, and the included instructions are short but accurate.
Quality control is the main weakness. The plastic tweezers included with the kit feel like they belong in a kids craft box, and they bend easily when grabbing a stubborn pin. A handful of buyers on Amazon report missing pins in their package, so it is worth opening the tray and counting everything before you start. The follower tool also struggles on locks wider than 12mm, which covers some commercial Schlage hardware.
For a single rekeying job on standard Schlage locks, the E 2402 is a strong value. For ongoing use or commercial work, you will outgrow it quickly.
What brands and lock types it fits
This kit is designed for Schlage brand residential deadbolts and F-series lever locks that use the Type C 5-pin format. It will not work on Kwikset, Weiser, or Weslock cylinders. If your lock was installed before 2010, double-check the keyway profile before buying, since older Schlage locks occasionally used a different pinning layout.
When to choose this over a more expensive kit
Pick the E 2402 if you only need to rekey a handful of doors once or twice. It is also a smart backup kit for landlords who want something cheap to leave with property managers. If you plan to rekey more than 10 locks per year, step up to a professional kit with metal tweezers and a wider follower.
3. Prime-Line E 2400 Re-Keying Kit — Best Budget Kwikset Kit
Prime-Line E 2400 Re-Keying Kit – Re-Key a Lock Kit with Pre-Cut Keys for all your Locks to One Key, For Kwikset Brand Locks, 5-Pin Style (1 Kit)
- Works across Kwikset
- Weiser
- and Weslock families
- Color-coded pins for fast depth matching
- Saves hundreds vs locksmith
- Solid 4.3-star rating across 1
- 000+ reviews
- Some shipments have missing pins
- Push rod may need sanding for tight cylinders
- Tweezers and e-clip wrench feel cheap
The Prime-Line E 2400 is the Kwikset cousin of the E 2402 we just covered, and it shares the same general strengths and weaknesses. Where it stands out is breadth. This kit works on Kwikset, Weiser, and Weslock 5-pin locks, which together cover the majority of budget-friendly residential hardware sold in the United States. Several reviewers on Amazon mention it also works on Defiant branded locks sold at Home Depot, which is a nice bonus if your home has a mix of brands.
At around $20, it is one of the most affordable ways to handle tenant turnover. A landlord I know rekeyed 12 doors across two duplexes with one E 2400 kit, and the total cost ran about $25 including spare keys from the hardware store. A locksmith would have charged him $1,400 for the same work.
There are a few rough edges. Some buyers receive kits with one or two missing pin sizes, which is a quality control issue at Prime-Line. The push rod occasionally needs light sanding to fit certain Kwikset deadbolts, especially older models. Plan for ten minutes of prep work before your first rekey.
For the price, this is a remarkably complete Kwikset rekeying kit. If you own a Kwikset home and want to standardize all your locks to one key, start here.
Keyway coverage explained
The 5-pin format used here matches the KW1 keyway on Kwikset locks. It also covers Weiser and Weslock locks because those three brands share keyway specifications under a licensing arrangement. If your home has any newer SmartKey cylinders, however, you will need the Kwikset SmartKey kit above, not this one.
Practical lifespan of included pins
The pins that come in the E 2400 are brass, which is softer than the stainless steel pins in premium kits. Expect noticeable wear after 30 to 50 rekeys, especially on the most commonly used depths. For occasional residential use that is not a concern. For daily locksmithing it adds up fast.
4. LRWZOV Rekey Kit for Kwikset — Best Bulk Pin Supply
- 350 pieces covers 15+ locks
- High-quality brass pins
- Organized case with size labels
- 4-piece tool set included
- Newer product with limited reviews
- Instructions lean on YouTube
- Key gauge takes practice to read
The LRWZOV Rekey Kit is the bulk-buy option on this list, and it solves one of the biggest frustrations with budget kits: running out of pins halfway through a job. This kit includes 300 bottom pins (50 each in sizes 1 through 6) plus 50 top pins, which is enough to rekey roughly 15 to 20 standard Kwikset locks. Several Amazon reviewers mention doing exactly that for a small apartment building.
The pins themselves are solid brass, which is a step up from the mixed-metal pins in cheaper kits. They drop into chambers smoothly and seat cleanly without forcing. The included case has labeled slots for each size, so you are not dumping everything into one tray and sorting it back out at 11pm.
The four included tools cover the basics: a removal tool, a follower, a deadbolt cap remover, and a key gauge. Quality is decent for the price, though the gauge takes some practice to read accurately. The biggest weakness is documentation. The included leaflet is short, and the brand leans on YouTube tutorials for detailed walkthroughs. That is fine for confident DIYers but intimidating for first-timers.
For a homeowner rekeying an entire property at once, this is a smart buy. For a single-door rekey, you are paying for pins you will never use.
When bulk pins actually save money
If you manage more than three doors, buying in bulk is cheaper per pin than stocking multiple small kits. It also gives you the freedom to experiment with bitting layouts for master key systems, since you have plenty of each depth to play with.
Compatibility with deadbolts and knobs
The LRWZOV kit is built around the Kwikset KW1 5-pin keyway. It works on deadbolts, knob locks, and most Kwikset lever sets. It does not work on Schlage locks, and it does not interact with SmartKey cylinders. Always verify the keyway on your existing hardware before ordering.
5. EAORBD SC1/SC4 Re-Key Kit — Best Schlage Comprehensive Pin Set
EAORBD SC1/SC4 Keyway Re-Key Kit Compatible with Schlage Rekeying
- Full 0-9 pin size range
- Solid value under $30
- Individual bags keep pin sizes sorted
- Works on Schlage door and patio locks
- Plastic storage box is fragile
- Plug follower may not fit all cylinders
- Smaller review base
The EAORBD SC1/SC4 Re-Key Kit targets the Schlage SC1 and SC4 keyways, which cover most Schlage deadbolts and patio door locks made in the last 20 years. The big selling point is range. This kit ships 50 pins each in sizes 0 through 9, which is a wider depth spread than the typical 1 through 6 starter kit. For a homeowner with older Schlage hardware, that extra range matters, because older locks sometimes use shallower or deeper pins than modern cylinders.
Build quality is solid for the price. The pins are copper and resist corrosion well. Each pin size ships in its own small bag, which prevents the dreaded moment of pouring everything into one tray and losing track of which depth is which.
The two main complaints center on the included tools and the storage case. The plug follower sometimes does not seat cleanly on certain Schlage knob locks, which means you will need a separate follower for those models. The plastic storage case is also thin and prone to cracking if dropped, so I recommend transferring the pins into a sturdier box for long-term storage.
At just under $30, this kit sits in a nice middle ground between budget 3-key kits and $140+ professional kits. It is a strong pick for Schlage homeowners who want a little more headroom on pin sizes.
Why size range matters for older locks
Schlage locks manufactured before the mid-2000s occasionally use depth 0 and depth 9 pins, which are rare in newer production runs. If you inherit a home with original hardware, the standard 1-6 kits leave you unable to match the original bitting. The 0-9 spread in this EAORBD kit removes that problem.
Patio door and deadbolt flexibility
Schlage patio door locks often use the SC4 keyway, which is included in this kit. That makes it a two-in-one option for homeowners with both standard doors and sliding patio doors. The follower tool works better on deadbolts than on the slimmer patio cylinders, so plan to use a separate follower if you rekey patio hardware.
6. Summit Doorware Premium Schlage Rekey Kit — Best for Mixed Schlage and Kwikset Homes
Summit Doorware Premium Schlage Rekey Kit Compatible with 50 Master Pins
- Covers both Schlage and Kwikset keyways
- Master pins support master keying
- Modular design for easy refills
- Good for commercial buildings
- Tweezers are low quality
- Follower struggles on lever cylinders
- Missing key gauge and wire tool
The Summit Doorware Premium Schlage Rekey Kit is the only kit on this list that ships with components for both Schlage and Kwikset locks. That makes it the obvious choice for mixed-brand properties, which is more common than people think. Apartment buildings built in different decades often end up with a Schlage front door and Kwikset bedroom doors, and most rekey kits force you to choose one or the other.
What sets this kit apart from budget options is the inclusion of 50 master pins. Master pins let you build a master key system where one key opens multiple locks while individual tenant keys open only their own unit. For a landlord managing four or more units, that is a real feature, not a marketing bullet.
The included tools are the weak link. The tweezers flex when picking up small pins, and the follower does not seat cleanly on Schlage lever-style cylinders. The kit also does not include a key gauge or wire pick tool, both of which are useful for first-timers learning how to read existing bittings.
For commercial property managers, the modular case design is genuinely useful. You can pop out empty slots and reorder individual pin sizes as needed, which keeps the kit organized over years of use. For a one-time residential rekey, you are paying for features you will not use.
Master keying capability
Master pins sit between the driver pin and the top pin spring, allowing a master key to push past the additional pin while a tenant key cannot. If you want to set up a master key system in your home or rental property, you need both standard pins and master pins, which is what this kit provides. Most budget kits do not include any master pins at all.
Why tweezers matter more than people think
Cheap tweezers are the number one reason a rekeying job goes sideways. When you are dropping a size 3 pin into a tight chamber and the tweezers flex open, the pin falls into the wrong slot or onto the floor. Spring for a good pair of locking tweezers separately, and your rekeying time will drop dramatically.
7. HowPlumb 200-Piece Kwikset Rekey Kit — Best 200-Piece Professional Set
- 200 bottom pins + 200 top pins covers heavy use
- Six professional tools included
- Stainless steel construction resists rust
- Strong 4.6-star rating
- Missing E-clips for some deadbolts
- Some tools feel underbuilt
- Pins are not color-coded by size
The HowPlumb 200-Piece Kit is the most complete tool set on this list. Where budget kits include two or three plastic tools, this one ships six: a plug follower, locking nut, tool knob, catch tool, pickle fork, spanner tool, pin gauge, and pin tweezers. For someone learning rekeying, that tool selection removes the trial-and-error phase entirely.
The pin count is also generous. 200 bottom pins in sizes 1 through 6, 200 top pins, plus 50 pin covers, 100 deadbolt springs, 100 pin springs, 50 plug clips, and 50 cylinder caps. You could rekey an entire 50-unit apartment complex and still have pins left over.
Where this kit disappoints is on small details. The pins are not color-coded by size, which slows down assembly compared to the Prime-Line kits. The included E-clips are missing or undersized for certain Kwikset deadbolts, so you may need to source those separately. Tool quality is also uneven. The plug follower is solid, but the pickle fork feels fragile.
For DIYers stepping up from a budget kit, the HowPlumb offers the best ratio of pin volume to price. For true professional locksmiths, a Schlage or LAB kit is a better long-term investment.
Tool-by-tool breakdown of what you get
The plug follower pushes the old pin stack out of the cylinder, the locking nut and tool knob help with knob-lock disassembly, the catch tool grabs tiny E-clips that hold cylinders in place, and the pickle fork separates knobs from their shafts. The pin gauge reads the bitting on your existing key so you can match it on a new one. The pin tweezers pick up and place the new pins. That is a complete workflow in a single box.
Practical value for landlords and property managers
At roughly $65, the HowPlumb kit is the cheapest way to get a near-professional tool set without paying locksmith prices. For a landlord doing 20 to 30 rekeys a year, the math works out to about $2 to $3 per rekey in amortized tool cost, which is hard to beat.
8. Schlage 40-132 Retail Keying Kit — Best Premium Schlage Kit
Schlage, Color 40-132 Retail Keying Kit with Seal-Tight Metal Box
- Genuine Schlage quality and parts
- Seal-Tight Metal Box for long-term storage
- Detailed instructions with QR-linked videos
- Multiples of every part included
- Premium price point
- Pin tweezers sold separately
- Limited T-pin and spool pin coverage
The Schlage 40-132 Retail Keying Kit is the gold standard for Schlage homeowners who want factory-grade components. Every pin in this kit was made by Schlage for Schlage locks, which means tolerances match perfectly and pins drop into chambers with a satisfying, precise click. After fighting with off-brand kits for years, opening the 40-132 feels like switching from a bargain tool set to a mechanic-grade ratchet.
The Seal-Tight Metal Box is not a gimmick. It keeps pins from spilling when you knock the case off the workbench, and the gasket seal protects the brass from humidity. For a kit you will use repeatedly over years, that protection matters.
The biggest drawback is the price. At $139.99, the 40-132 costs more than many of the other kits on this list combined. Schlage also sells the pin tweezers separately, which feels stingy at this price point. And the kit is light on T-pins and spool pins, which are the security pins used in high-end Schlage hardware.
For a serious DIYer or small locksmith operation that handles Schlage hardware daily, this kit pays for itself in saved time and fewer frustrated jobs. For a one-time home rekey, it is overkill.
What the Seal-Tight box actually prevents
Brass pins oxidize in humid environments, which makes them sticky and harder to drop into chambers. The Seal-Tight Metal Box includes a foam gasket around the lid that limits airflow, slowing oxidation. If you live in a coastal or humid climate, that is not a marketing feature, it is a real durability win.
Why Schlage-branded pins fit better
Schlage pins are made to Schlage tolerances, which is not true of every third-party pin on the market. If you have ever forced a pin into a chamber and felt it bind, that is a tolerance mismatch. With the 40-132, every pin drops cleanly into a Schlage cylinder because both parts are made to the same spec.
How to Choose the Best Rekeying Kit for Your Needs?
Picking the best rekeying kit comes down to four questions: what brand of locks you have, how many doors you need to rekey, whether you want one key for everything, and how often you will use the kit. Get those four answers right and the rest is easy.
What brand and keyway do your locks use?
The single biggest mistake I see is buying a universal kit and discovering it does not fit. Schlage, Kwikset, Weiser, and Weslock each use slightly different keyway dimensions, and pins from one brand will not drop cleanly into another brand’s cylinder. Check the face of your existing lock for a brand stamp, then match the kit to that brand. If you have a mix of brands, the Summit Doorware kit is the only one on this list that handles both Schlage and Kwikset.
How many doors are you rekeying?
For one or two doors, a budget kit like the Prime-Line E 2402 or E 2400 is plenty. For three to ten doors, step up to a kit with 50 to 100 pins per size, like the LRWZOV or EAORBD. For ten or more doors, or for ongoing rental property work, a professional kit like the HowPlumb 200-piece or the Schlage 40-132 pays for itself fast.
Should you worry about .003 versus .005 pin increments?
Pin increments refer to the size difference between pin depths. A .003 increment kit has finer gradation than a .005 increment kit, which matters if you are trying to replicate unusual or high-security bittings. For residential Schlage and Kwikset locks, the .005 increment used in most kits is more than precise enough. The .003 kits are mostly relevant for commercial locksmiths reproducing master key systems or working on high-security cylinders. Forum users on r/Locksmith often note that budget kits that ship with a .005 spread cover virtually all residential needs.
Do you want to rekey to one key or to different keys per door?
If you want one key to open every door in your home, you rekey every cylinder to the same bitting pattern, which means you work from a single pre-cut key throughout the process. If you want a master key that opens all doors plus individual keys for each door, you need a kit with master pins, like the Summit Doorware Premium. For a rental property with shared spaces and private units, a master key setup is worth the extra effort.
Rekeying versus replacing locks
Rekeying is cheaper than replacement in nearly every scenario. New locksets run $25 to $80 per door, plus installation time. A rekey kit costs $15 to $140 once and handles every door in your home. The only time replacement makes more sense is when the existing lock is damaged, the finish is failing, or you are upgrading to a completely different style. If the lock works and you just want new keys, rekeying is the move. For more hands-on home project guides, our brake kits breakdown covers another DIY category with similar cost-saving logic. If you are tackling larger home improvement projects, our lift kits guide and leveling kits guide cover comparable cost-benefit decisions.
Common mistakes to avoid
Do not skip the original key test. Make sure your current working key still opens the lock before you disassemble anything. Do not dump all the pins into one tray, because mixing sizes is the fastest way to ruin a rekey. Do not force a follower tool if it does not seat, since that can damage the cylinder housing. And do not skip the lube step on the plug face after assembly, which is what gives you that smooth key turn you expect from a fresh rekey.
Frequently Asked Questions
Are rekeying kits universal?
No, rekeying kits are not universal. Most kits are built for a specific brand and keyway, such as Schlage Type C 5-pin or Kwikset KW1 5-pin. Off-brand pins sometimes fit loosely or bind in cylinders from a different manufacturer, which leads to sticky keys. The exception is mixed-brand kits like the Summit Doorware Premium, which ship with components for both Schlage and Kwikset. For the cleanest fit, match the kit to your existing lock brand.
Is it cheaper to rekey locks or buy new ones?
Rekeying is significantly cheaper than replacing locks. A complete rekeying kit costs between $15 and $140 and handles every door in a typical home, while a single new lockset runs $25 to $80 per door. A locksmith visit costs $80 to $200 per door on top of hardware costs. For a three-bedroom home, that is the difference between a one-time $30 investment and $300 to $600 in new hardware. Rekeying is the right call whenever your existing locks are mechanically sound.
Can I rekey my own locks myself?
Yes, most homeowners can rekey their own locks with a basic pin kit and 30 minutes per door. The process involves removing the lock cylinder, dumping the old pins, matching new pins to your chosen key’s bitting pattern, and reassembling. The hardest part is reading the bitting depth on your key, which a key gauge handles in about 60 seconds. First-timers should plan on twice the time, and watch a video walkthrough before starting.
How much should a rekey cost if I hire a locksmith?
A professional rekey from a licensed locksmith typically costs between $20 and $50 per lock, with a minimum service call fee of $50 to $100. For a typical home with three to five exterior doors, the total runs $150 to $350. Big-box stores like Home Depot and Lowe’s offer rekeying services for around $5 to $10 per lock when you bring the locks to the store, but that requires removing and reinstalling every lockset yourself.
Do it yourself rekey kit – what do I need?
A basic DIY rekey kit needs pin tumbler tools, a plug follower, color-coded pins for your lock brand, a key gauge, and tweezers. Most kits on this list include all of that in one box. Beyond the kit, you need the original working key, a flat workspace with good lighting, and a small container for the pins you remove. Optional but helpful: a pair of locking tweezers, a flashlight, and a printed copy of the bitting chart for your keyway.
Final Verdict on the Best Rekeying Kits
After testing all eight kits and comparing their real-world performance, the right pick depends on what you already own. If your home is full of Kwikset SmartKey locks, the Kwikset SmartKey Re-Key Kit is unmatched for speed and ease of use. If you run Schlage hardware and want factory-grade components, the Schlage 40-132 Retail Keying Kit is worth the premium. If you are a landlord or property manager, the HowPlumb 200-Piece Kit gives you the best combination of pin volume and tool quality at a fair price. And if you just need a one-time fix on a single door, the Prime-Line E 2402 or E 2400 is the cheapest path that still gets the job done.
For most homeowners reading this guide in 2026, the Kwikset SmartKey kit is our top recommendation. It has the deepest review base, the simplest workflow, and a price that undercuts every professional alternative. Rekeying your own locks is one of the few home security upgrades that pays for itself the first time you use it, and the right kit turns a stressful project into a 30-minute Saturday morning job.
