When to Rekey vs. Replace Your Locks in California

The most common trigger for a lock change in California is moving into a new home or rental. The question most homeowners and renters face is whether to rekey the existing lock or replace it entirely. Rekeying changes the internal pin configuration so old keys no longer work, and it costs significantly less than buying and installing new hardware. If your existing lock is in good mechanical condition and is at least a Grade 2 rating, rekeying is the right call in most cases.

There are four situations where replacement makes more sense than rekeying. First, if the lock is worn, stiff, or has visible damage to the cylinder or housing, rekeying a failing lock just delays the inevitable. Second, if you are upgrading to a smart lock or high-security hardware, you will need a new unit regardless. Third, if the existing lock is a low-security Grade 3 that you want to upgrade, a rekey maintains the same weak hardware. Fourth, if the door bore hole is the wrong size for modern deadbolts, replacement may be required as part of correcting the installation.

We are not going to recommend a more expensive replacement when a forty-dollar rekey is the right answer for your situation.
