The honest answer up front: if your only goal is to stop juggling a fistful of keys, a keyed-alike replacement set may beat a rekey kit. A keyed-alike lockset set replaces the hardware and puts every door on one key before it ever reaches your house. A rekey kit is the right buy when you already own good locks and want new keys in them without paying a locksmith per cylinder. This guide covers both routes — rekeying and replacing — so you buy the right one the first time.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Below you’ll find five picks split by what they actually do: full replacement hardware, Schlage-compatible pin kits at three commitment levels, and one storm-door deadbolt that solves a completely different problem. Read on for the honest breakdown of the best lock rekey kit options and which one matches your door count.
Top Picks
How To Choose The Best Lock Rekey Kit
The first decision isn’t which kit — it’s whether you’re rekeying or replacing. Rekeying keeps the lock body already screwed to your door and swaps the small brass pins inside the cylinder so old keys stop working. Replacing throws out the whole knob or deadbolt and starts fresh. Rekeying is cheaper per door and keeps hardware you already trust. Replacing wins when your existing locks are loose, mismatched, or older than the doors themselves.
Match the keyway before you match the price
A keyway is the shaped slot the key slides into, and it decides whether a kit’s pins will even fit your cylinder. Schlage-compatible cylinders commonly use SC1 (the standard five-pin residential keyway) or SC4. If your key says “Schlage” on the bow and the lock is a standard residential deadbolt, an SC1/SC4 kit is the direction to look. Kwikset and off-brand cylinders use different pin diameters, so a Schlage pin set will not seat correctly in them.
Count your cylinders, then count your pins
Each cylinder you rekey consumes one bottom pin and one top pin per chamber, plus a spring. A five-pin cylinder therefore eats five of each. Kits that ship 50 of every bottom pin size (0 through 9) plus a top-pin supply will carry you through a whole house and then some. Smaller starter kits do the same job for two or three locks. Buy for the number of cylinders on your property, not the number you plan to do this weekend.
The tools decide how pleasant the job is
Three accessories do most of the work, and skipping any of them turns a twenty-minute job into an evening. The follower is a rod that pushes the plug out while keeping the springs from launching across the room. The clip remover is the small hook that frees the retaining clip on the back of the cylinder. The gauge decoder is a slotted card that measures an existing pin so you can match it. Factor all three into what you’re willing to pay.
Decide if you need master pins
Master pins let one cylinder accept two different keys — one for the homeowner, one for a cleaner or a tenant. A standard rekey kit pins a lock to a single key only. If you want a master-key setup, you need a kit that explicitly includes master pins. Do not assume a kit supports it just because it includes a lot of pins.

Detailed Reviews
1. Brotima 3 Pack Keyed Alike Front Door Knob and Deadbolt Set
Our pick — 4.5+★ from 950+ verified ratings; the strongest balance of quality and price.
Three doors, one key, and the hardware to make it stick — without a locksmith visit.
If you just want every exterior door opening on the same key, this set gets you there by replacing the hardware instead of fiddling with pins. You get three matching knob-and-single-cylinder-deadbolt pairs, each built to ANSI Grade 3 (a residential security standard covering basic strength and durability). The maker rates the lockset for more than 250,000 simulated use cycles. That cycle count speaks to how the latch and bolt hold up over years of daily slamming, not weeks.
The practical win is how many keys ship in the box. Each set ships with a generous bundle of keys cut to the same bitting (the key’s cut pattern), so every member of the household can have one without a trip to the key cutter. The cylinders are stated to be SC1-style Schlage-compatible keyways, which is the detail worth noting: a rekey kit like the ones further down this list can service these cylinders later if you ever need to change the key again. The deadbolt uses a single cylinder, so the thumb-turn lives on the inside and the key goes outside — the standard arrangement for an entry door.
What wins buyers over is how smoothly the latch and bolt turn. The recurring theme in the feedback is that the latches and bolts turn cleanly and keep doing so, and the oil-rubbed bronze finish holds its look rather than scratching off at the first bump. The build is described as medium-grade rather than premium — solid, but not a bank-vault feel. Knobs run larger than some expect. That’s a comfort preference, not a defect. And this is replacement hardware: if your existing locks are fine and you only want fresh keys, a pin kit costs less and does the job.
What earns the top spot
- One key opens all three sets from the start — no locksmith, no trip to the key cutter
- ANSI Grade 3 residential rating, with the maker claiming over 250,000 simulated use cycles
- Single-cylinder deadbolt plus keyed knob gives two locking points per door
- Corrosion-resistant stainless steel with an electroplated oil-rubbed bronze finish
- Ambidextrous handles fit left- or right-hinged doors without ordering a specific hand
Where it asks something of you
- You’re replacing hardware, not rekeying — the old locks come off
- Knob size runs larger than a standard rose, which some hands notice
- Rated medium-grade build, so set expectations at solid-residential rather than heavy-commercial
Made for: anyone moving into a place with mismatched locks, or anyone tired of a keyring that jingles like a set of wind chimes.
Think twice if: your current locks are tight and you only want a new key — the pin kits below do that without touching your doors.
2. EAORBD SC1/SC4 Keyway Re-Key Kit Compatible with Schlage
A whole pinning kit that genuinely disappears into a jacket pocket.
This kit fits in a coat pocket, so you can carry it to a rental property, yet it holds 50 of every bottom pin size from #0 through #9, a top pin, a removal tool, a follower, and a gauge decoder. That’s everything needed to rekey a Schlage SC1 or SC4 cylinder from scratch. The pins step up in precise increments — #0 measures 4.191mm and #9 measures 7.62mm — so matching an existing key’s cut depths is a matter of reading the numbers rather than guessing.
Matching a new Schlage B60 deadbolt to the older locks already on the house is the exact job this was built for, and it handles that without drama: the pins seat and the follower lines up at the right diameter for a standard cylinder. The gauge decoder is the weak link. It’s roughly cut and hard to read with confidence, so if you match pins by measurement rather than by key code, plan on double-checking the fit.
The honest caveat is scale. This is a great fit for one or two cylinders, an apartment turnover, or a single front door — not for a property manager servicing forty units. There isn’t enough of any one size to keep going indefinitely, and the follower bar can be fiddly to seat the first time. Both are solved by slowing down rather than buying more kit.
The strongest argument: you get a full range of numbered pins, a follower, a removal tool, and a decoder in a form factor that fits a pocket — and the price sits in budget-kit territory rather than professional-toolbox territory.
The part to plan around: that gauge decoder. Treat it as a rough guide and confirm each pin by test-fitting the cylinder before you close it up.
Reach for this if: you have one or two Schlage cylinders and want to try rekeying before committing to a bigger kit.
Look elsewhere if: you’re rekeying a whole building — you’ll want the 50-per-size volume of the eBuilderdirect set below.
3. eBuilderdirect SC1/SC4 Re-Key Kit
Enough pins to pin every cylinder in a house and still have spares rattling in the box.
The number that decides this one is 50. Fifty pins of every size from #0 to #9, plus 25 top pins, plus a removal tool, a follower, and a gauge decoder — that’s the volume that lets you rekey a whole property on one purchase instead of ordering refills mid-project. Weighing in at 8 ounces, the kit stays light enough to carry from door to door without thinking about it. The compatibility list is wider than most here, covering Schlage SC keyway along with Baldwin, Dexter, Emtek, and Pegasus locks, which is useful if your doors are a mix of vintages.
Where this really separates from the EAORBD kit is staying power. You can rekey a series of locks and come back for more without running dry on a common size, and if you botch a pin choice there are backups waiting. The pin code printed on the key, or the gauge decoder, tells you which pin to drop in each chamber. The trick is that disassembly is the slow part, while the actual repinning takes about two minutes per cylinder. Set aside patience for the disassembly, not the rebuild.
Here’s the honest trade-off. The included tools are functional but not fine-tuned: the plastic follower bar can need a light filing to slide freely, and the removal tool is designed for a different keyway than Schlage, so it won’t suit every clip. If you’re rekeying a Schlage smart lock or a lever-style cylinder, budget a few minutes to modify or substitute a tool. The pins themselves are fine — the tools are the rough edge.
Why it earns its spot: 50 pins per size across ten sizes, 25 top pins, and support for five lock brands is a genuinely broad kit for a mid-range price.
What will slow you down: the follower and removal tool may need a quick modification before they cooperate — have a file handy.
Best fit for: a homeowner with a full set of doors to unify, or anyone doing this job properly across several cylinders.
Not the pick if: you’re working on a lever-style handle with a duck-bill cylinder — that shape tests the follower, and you’d be better served by more forgiving tools.
4. Ideal Security Model GLK Deadbolt for Storm and Screen Doors
A deadbolt sized for the door that never had one — template and all.
Different problem, different tool. A storm or screen door isn’t built to take a standard entry deadbolt, and drilling one without a guide is how you end up with an off-center hole and a useless door. This kit ships with a template that takes the guesswork out of positioning, which is the reason it works on doors that start with no lock at all. Included hardware covers the outside deadlock, the inside deadbolt, the spindle, the strike, shims, and screws — so there’s nothing else to buy before you start.
Fit is broad. It’s designed to work on a storm or screen door around 3/4 of an inch thick, and the spindle is field-trimmable, which is how it adapts to a door that doesn’t match the box. The shims handle the small gap that shows up between the interior and exterior plates on many storm doors — that’s the piece most kits forget. The white painted finish suits a standard storm-door frame and won’t jump out visually.
The recurring friction is the instructions. They’re thin on spindle trimming, and that’s the step where people get stuck — one approach is to trim with a proper metal-cutting tool rather than household scissors, since the spindle is metal. Overtightening the screws is the other way to jam the deadbolt: it presses the plates into each other and locks up the throw. Go finger-tight first, check the action, then finish. Durability gets a mixed read — the general impression is sturdy, though a minority find it less solid than expected. For a screen door threatening wandering at night, it does the job.
What makes it work
- Template included, so a door with no existing lock can still be drilled accurately
- Complete kit: outside deadlock, inside deadbolt, spindle, strike, shims, screws
- Works on a door around 3/4 inch thick with a field-trimmable spindle
- Shims handle the inter-plate gap common on storm doors
Where the job bites back
- Instructions gloss over spindle trimming, the step most people stall on
- Screws overtighten easily and jam the deadbolt throw
- Durability reads mixed — sturdy on the whole, less so for a minority of installs
Choose it when: your storm or screen door has no lock and you need a keyed deadbolt that fits rather than a deadbolt that fights back.
Go in prepared for: reading past the instructions — trim the spindle with a proper cutting tool and hold the screws finger-tight until the action is smooth.
5. Summit Doorware Schlage Rekey Kit
The kit you buy when rekeying isn’t a one-off — it’s a standing job.
Master pins are the whole reason to step up here. Fifty bottom pins per size (0 through 9), fifty master pins, fifty top pins, and fifty springs, all in a sealed plastic box with a latch that keeps the compartments shut between jobs. Master pins let a single cylinder accept two different keys — the landlord’s key and the tenant’s — which is a capability the smaller kits simply don’t have. For a rental property, a retail space, or a home with a cleaner who needs access, that’s the difference between a kit that does the job and one that doesn’t.
The steel components are stated as alloy steel rather than brass, and the box is built to be resealable so pins stay sorted. The rest of the tool line — a clip removal tool, a key gauge, and the pin-depressing wire — is where things get uneven. The follower in particular is standard-sized rather than shaped for Schlage cylinders, so the trick is to use the flat side and guide it through rather than trying to fit it over the plug. A key gauge is included, but a caliper gives more confidence when matching an unknown pin, and small tweezers help when seating the last spring and cap.
Compatibility is the honest caveat here. It handles Schlage keyway locks well across deadbolts, knobs, and smart-lock cylinders, but knob-style cylinders with the lip are the finicky ones, and a lever-style cylinder with a duck-bill shape will not take the follower without a workaround. Read the compatibility notes before you buy, and if your doors are a mix of Schlage and non-Schlage, this kit only covers half of them.
The case for it: master pins plus a resealable case plus all four pin types in one kit is what a repeat job actually needs, and it’s the only pick here that ships master pins at all.
What to plan for: the follower and clip removal tool are the rough spots — expect to modify or substitute them, and budget for tweezers and a caliper you’ll want on hand.
The right call for: landlords, property managers, or anyone rekeying regularly enough that master-pin capability and a resealable box are worth the step up.
Overkill if: you have one or two deadbolts and no need for two-key access — the EAORBD or eBuilderdirect kits do that job for less.
Know the Specs
Keyway (SC1 vs SC4 vs Kwikset)
A keyway is the cross-section shape of the slot the key enters. Schlage-compatible cylinders commonly use SC1 or SC4, and the pins sized for those keyways will not seat correctly in a Kwikset cylinder or an off-brand clone. Check the stamp on your key bow and the model number on the lock face before you buy pins — this is the single check that prevents a wasted purchase. A kit that names SC1 and SC4 is covering the two most common Schlage residential patterns.
Bottom Pin Numbers 0–9
Each bottom pin in a Schlage-compatible kit is numbered by length, and the number corresponds to a cut depth on the key. The scale runs from #0 at 4.191mm up to #9 at 7.62mm in even steps. When you rekey, you read the cut depths of your existing working key and drop the matching pin into each chamber. Get one wrong and that chamber won’t turn smoothly. This is why a gauge decoder or a key code is useful — it turns a measurement into a number.
Followers and Why They Matter
A follower is a rod that pushes the cylinder plug out while keeping the springs and top pins from launching across the room. A properly sized follower slides through the plug bore at the same diameter. An oversized or differently shaped follower makes the plug bind and turns a two-minute job into a wrestling match. Many kits include one that is “standard-sized” rather than tailored to a specific cylinder shape — using the flat side, and guiding the plug through steadily, usually solves it.
Master Pins and Two-Key Access
Master pins sit alongside the bottom pins in a chamber so the cylinder accepts two different keys — one that lands on the regular pin stack and one that lands on the master stack. A kit that includes master pins supports this. A kit without them pins a cylinder to a single key only. If you need a tenant key and an owner key for the same lock, confirm master pins are in the box before you buy — not every “complete” kit has them.
