Getting the keys to a new home feels like the end of the process, but it should also be the start of a simple security habit: rekeying the locks. You have no way of knowing how many copies of the old keys exist or who holds them.
What does it mean to rekey a lock?
Rekeying replaces the small pins inside the lock cylinder so that a new key works and the old ones do not. The lock itself stays on the door. Because you are not buying new hardware, it usually costs less than replacing every lock.
You do not know who else has a key
Even when a seller or landlord hands over every key they have, others may still exist. Keys are often given to:
- Real estate agents and lockbox services
- Previous occupants, their family and friends
- Cleaners, gardeners, dog walkers and contractors
- Former roommates or house sitters
Any of those keys could have been copied. Rekeying makes all of them useless in one visit.
A practical upgrade on moving day
A locksmith can usually rekey several doors in a single visit, and it is a good moment to key them alike so one key opens the front door, back door and garage entry. Ask for a few spare keys while the technician is there.
Renters: talk to your landlord first
If you rent, check your lease before changing anything. Many leases require the landlord to have a working key, and some landlords rekey between tenants as standard practice. If yours has not, it is reasonable to ask. If they agree to let you arrange it, give them a copy of the new key so you stay within the agreement.
Rekey after renovations too
Major work on a home often means keys and lockbox codes passed around among several trades. Once the work is finished, rekeying closes that gap.
Rekey or replace?
Rekeying is the better value when your locks are in good condition. Replacement makes more sense when locks are worn, rusted or damaged, when you want a higher-security or smart lock, or when you want a new look. Our lock change page compares the options.
