Why rekey your locks when you move

Updated November 2026 · Locksmith Of Berkeley

Nobody can tell you how many copies of your new front-door key exist. Rekeying makes that question irrelevant, for less than new locks.

The key count nobody knows

Think about who has held a key to your new place. The sellers, and their kids. Former tenants. The property manager. A cleaner, a dog walker, a painter, the agent who ran open houses. In Berkeley, where many houses have been rentals for decades, the list can be very long.

Most of those people are honest. That's not the point. You can't know, and you can't collect the keys back. Rekeying cancels them all at once.

What rekeying is

Inside a pin-tumbler lock, a row of small pins must line up for the cylinder to turn. Your key's cuts do the lining up. Rekeying replaces those pins with a new set that matches a new key. The lock body, the knob and the deadbolt stay where they are.

No new hardware means a lower bill than replacing locks, and a locksmith can do several doors in one visit. If the locks share a brand and keyway, they can all end up on one key.

Rekey or replace?

  • Rekey when the locks work smoothly and you just want the old keys dead.
  • Replace when a lock is worn, rusted, cracked or sticky even with the right key.
  • Replace when you want a different kind of lock: a stronger deadbolt, a restricted key, a keypad.
  • Not sure? Ask for both prices. A locksmith can tell once they see the lock.

If you rent

Talk to the landlord before touching any lock. Many landlords rekey between tenants as a matter of course, so ask if it was done. Rules differ by city and by lease, so check yours.

If it wasn't done and the landlord agrees, offer to arrange it and hand them a copy of the new key. Changing a rental's locks without permission can breach the lease.

The doors people forget

Garage side doors. Back gates onto a path. Basement doors. Mailbox locks. The in-law unit out back. List every lock before you call so the quote covers them all. In Berkeley and Albany, call 510-803-3123 for a quote before any work.
