Rekey or Replace Your Locks? How to Choose
Both stop old keys from working, but they are not the same job. Here is how to tell which one your doors need.
Rekey vs. replace: the short answer
Rekeying changes the inside of your existing lock so it works with a new key. The old key no longer turns it. The lock itself stays on your door.
Replacing swaps the lock for a new one, with new keys. It is the better choice when the lock is damaged, worn or not strong enough for the door.
Which one fits your situation?
Start with the condition of the lock, then what you want from it.
Rekey when…
the locks are in good shape and you only need old keys to stop working: you moved in, a key was lost, a tenant left, or you want every door on one key. See house lock re-key or business lock re-key.
Replace when…
the lock is worn, sticks, was damaged in a break-in, is a weak builder-grade lock, or you want a keypad, smart lock or a different finish. See house lock change or business lock change.
Still unsure? Call and describe the lock. We will tell you honestly which makes sense, even if it is the simpler one.
Common questions about both jobs
What people usually want to know before they decide.
Is a rekeyed lock less secure?
No. Once rekeyed, the old key is useless. How strong the lock is depends on the hardware, not on whether it was rekeyed.
Can all my locks use one key?
Often yes, when the locks are compatible. It is a common reason people rekey.
Do I need new locks after a break-in?
If the lock or door was damaged, replace it. If the lock is intact but someone had a key, rekeying may be enough.
What about keypad and smart locks?
Those are replacements, not rekeys. See electronic and keyless entry locks.
Times it is smart to do one of them
Most people call us for one of these reasons:
- You bought or moved into a home and do not know who has a key.
- Keys were lost or stolen.
- A roommate, partner, contractor or tenant moved out.
- A lock is worn out, sticky or hard to turn.
- You want stronger hardware on your main entry.

Rekey vs. Replace Questions
What is the difference between rekeying and replacing a lock?
Rekeying changes the inside of the existing lock to work with a new key. Replacing installs a new lock. Both stop old keys from working.
Which is usually less expensive?
Rekeying is usually the lower-cost option when the lock is in good shape, because the hardware stays. Call (919) 769-3432 and you will hear the price for your doors before we start.
Can you rekey a lock without the old key?
Yes. A locksmith can rekey a lock that is in place on the door even when you do not have a working key.
Can you rekey a business lock?
Yes. See business lock re-key. For many doors and many keyholders, ask about a master key system.
