Illustration for Why You Should Rekey Your Locks When Moving

When you move into a new home, you have no way of knowing how many keys to the front door are still out there. Rekeying changes the pins inside your existing locks so every old key stops working, and it usually costs less than replacing the hardware.

Who might still have a key?

  • Previous owners or tenants, and their family and friends
  • Real estate agents and property managers
  • Cleaners, dog walkers, babysitters and contractors
  • Former roommates

Even when a seller or landlord says every key has been returned, copies are easy to miss. Rekeying removes the doubt.

What rekeying involves

A locksmith removes the cylinder, takes out the old pins and fits a new set matched to a new key. The lock body stays on the door. Several doors can usually be done in one short visit, and they can all be set to work with a single key.

Renters: talk to your landlord

Tenants can ask a landlord to rekey before move-in. Rules about who pays and whether permission is needed vary, so check your lease and local regulations. If the landlord agrees, they will usually want a copy of the new key.

After renovations

If contractors, painters or electricians had keys during a remodel, rekeying once the work is finished is a simple way to close that gap.

Rekey or replace?

Rekey when your locks are in good condition and you only need to cut off old keys. Replace when the locks are worn, damaged or basic, or when you want a higher-security, smart or keypad lock. A locksmith can tell you which makes sense on site. See our residential locksmith services.
