Lock Rekeying in New Jersey
New keys. Same locks. A flat price you know before any work begins.
Three Things to Know
- Move-In Rekeying
Every exterior lock can be rekeyed so the previous owner's keys, the landlord's copies, and the contractor's spares all stop working on day one.
- Security Reset After a Lost Key
When a key goes missing and you're not sure where it ended up, rekeying closes that risk quickly, without replacing the hardware.
- Same-Key Convenience
If you have several locks on the property, they can all be keyed to match a single new key so you're carrying one key instead of four.
The Guide
Rekeying is the quickest way to cut off access for a key you can no longer trust. The internal pins inside your existing cylinder get changed so only fresh keys work. The lock stays. The hardware stays. You just stop worrying about who might still have a copy.
Why Rekeying Is Often the Right Call
A lot of people assume that if something is wrong with a key situation, they need a new lock. That’s often not true. The lock itself is just a shell. The cylinder inside is what reads your key. Rekeying swaps the readable part, not the whole assembly.
This matters in a few common situations. You’ve bought a home and the sellers handed you two keys, but you don’t know how many copies exist or who has them. The right move isn’t to replace every lockset. It’s to rekey every exterior cylinder and hand out fresh keys to the people who actually live there.
Same logic applies when a key goes missing. You retrace your steps, check your pockets, nothing. The key might be in a parking lot somewhere. It might be in someone else’s pocket. Rekeying that afternoon costs less than your co-pay at an urgent care, and it closes the risk completely.
Landlords and property managers rekey between every tenancy as standard practice. A tenant returns all their keys at move-out, but duplication is easy and copies take two minutes to make. Starting fresh with a rekeyed cylinder means the new tenant’s key history begins on day one of their lease, not on an unknown date in the past.
Ask for the flat price for rekeying before any work begins. You are not committing to anything until you hear the number and say yes.
What Happens During the Job
Rekeying kits sized for all the major residential brands, Schlage, Kwikset, Baldwin, Yale, Defiant, and others, cover most jobs. The cylinder comes off the door without damaging the hardware, gets disassembled, the pin stacks swapped to match a new blank, and reassembled.
If you want multiple locks keyed alike, they get done in sequence, so one key opens all of them when finished. New keys are cut on site and every lock tested before the job is done: you turn the key, the bolt moves, the door opens and closes cleanly. That’s the test, and it should be run every time.
Rekeying vs. Lock Replacement
The question comes up on almost every rekeying call. Rekeying wins on cost and speed when the hardware is solid. A lock that’s stiff, loose, or badly scratched around the keyway might need the full swap instead. The hardware gets reviewed on arrival, and if something changes the picture, expect a pause and an explanation before the plan changes. The price quoted for rekeying is the price you pay for rekeying. Any additional work is a separate conversation.

Weighing the Options
Rekeying vs Replacing the Lock
Rekey the cylinder
- Same hardware, new keys
The pins change, so every old copy stops working.
- $40 to $85 per lock
The cheapest full security reset there is when the hardware is sound.
- Quick work
A whole house is usually done inside an hour.
Replace the lock
- Worn or damaged hardware
A stiff, loose, or corroded lock needs the full swap.
- A grade upgrade
Moving from builder-grade Grade 3 to Grade 1 requires new hardware.
- Smart lock plans
Adding electronic access means replacement, not rekeying.

Residential Questions, Answered
Frequently Asked Questions
What exactly happens during a lock rekey?
The cylinder contains a row of small spring-loaded pins cut to match your current key. The cylinder is removed, those pins replaced with a new set matched to a fresh key blank, and reassembled. Your old key no longer turns the plug. The new key does.
How much does rekeying cost in NJ?
A single lock typically runs $40 to $85 depending on the brand and cylinder type. If you're rekeying a full house with three or four locks, the per-lock cost often drops when bundled. Ask for a flat quote before dispatch.
Can any lock be rekeyed?
Most standard pin-tumbler residential locks can be rekeyed. A few proprietary or high-security cylinders require manufacturer-specific service. This should be confirmed when you submit a request.
Is rekeying as secure as replacing the lock?
If the lock hardware itself is in good shape, yes. Rekeying gives you the same security as a new lock of the same model. If the hardware is worn, loose, or damaged, that should be flagged, with a discussion of whether replacement makes more sense.
How many new keys will I get?
As many as you need. Most people want two to four copies. Confirm the count before the job so it's included in the quoted price.
How long does it take?
One lock takes 15 to 25 minutes. A full house with four exterior locks is usually done in under an hour.
