Rekey vs lock change in Los Angeles: which is cheaper — and when “cheap” is the wrong goal

Rekeying means the locksmith repins your existing cylinder so old keys stop working and new keys operate the lock. Changing the lock usually means replacing the lockset or cylinder entirely — materials plus labor. If the hardware is sound and you only care about who has keys, rekeying is often the cheaper path.

Replacement wins when the cylinder is worn, corroded, damaged from tampering, or you’re upgrading security grade. It also wins when you hate the brand, the finish, or the handle style — aesthetics aren’t trivial if you interact with that door daily.

Smart-lock crossover blurs the line: sometimes you’re “replacing” because the door prep never matched the gadget you bought online. If an installer warns about thin doors, odd backsets, or weak strikes, listen — shortcuts become rattling hardware later.

Commercial adds vocabulary: master-key systems, restricted keyways, and panic hardware fire ratings. Photograph the face of the lock and any markings before you call; it speeds honesty about parts availability.

When you’re ready, describe scope: how many cylinders, exterior vs interior priority, and whether everyone can exit safely tonight even if you defer secondary doors. Request help through LockUnlocked when you want a technician who covers your ZIP without a mystery national upsell script.
