What a Home Rekey & Lock Change Actually Involves — and Which One You Need
Rekeying and replacing hardware solve the same core problem — unauthorized key copies — but through different means. When we rekey a lock, our technician disassembles the cylinder, swaps out the internal pins, and reassembles everything so that only a brand-new key operates the lock. The existing deadbolt, mortise lock body, or door knob lock hardware stays exactly where it is; only the secret combination of the cylinder changes. This is ideal when your hardware is in solid mechanical condition and you simply need to eliminate the threat of old, outstanding keys. A full lock change, on the other hand, swaps out the entire hardware unit — a smart move when the mechanism is worn, the finish is damaged, or you want to upgrade to a higher-security grade at the same time.
The distinction matters because each situation calls for a different approach. Moved into a rental on Manhattan Beach's Highland Avenue? Rekeying is usually faster and eliminates the old-key risk immediately. Dealing with a mortise lock on an older Craftsman home whose cylinder is corroded or whose faceplate no longer seats flush? A complete door lock change may be the cleaner long-term solution. Our technicians assess the hardware on-site and give you an honest recommendation — not the most expensive option, but the right one for your specific door and frame.
