You cannot know how many copies of your new keys exist. Rekeying fixes that for a fraction of the cost of new locks.
What rekeying actually does
Rekeying changes the small pins inside a lock cylinder so it works with a new key. The lock body stays on the door, but every old key stops working. Because only pins and keys change, it usually costs much less than replacing the hardware.
You do not know who else has a key
Previous owners or tenants, their relatives, real estate agents, cleaners, dog walkers and repair crews may all have held a key at some point. Even if the seller or landlord says every key was returned, copies are easy to make and easy to forget about.
A simple, affordable upgrade
A technician can rekey every exterior lock in one visit and key them all alike, so you carry a single key for the front door, back door and garage entry. Most homeowners find it the most cost-effective security step they take after moving.
Renters: ask first
If you rent, ask your landlord to rekey before move-in. Many will, and some leases require it. If they decline, ask permission to book a locksmith yourself and give the manager a copy of the new key. Lease terms and local rules vary, so check yours.
Rekey after renovations too
Contractors, painters and electricians often receive spare keys. When the work is finished, rekeying makes sure those copies no longer open your home.
Rekey or replace?
Rekey when the locks are in good condition and you simply want control of the keys. Replace when locks are worn, rusted or low-grade, or when you want a high-security deadbolt or a smart lock. Our residential locksmiths can quote both.
Book it with the move
Add rekeying to your moving checklist alongside utilities and the change of address. It is quick, inexpensive and gives you certainty about who can open your door.
