Home Rekey and Lock Change: What the Difference Actually Means for Your Security
Rekeying a lock means a technician disassembles the lock cylinder and replaces the internal pins so that your old keys no longer work — only the new keys cut to the new pin configuration will operate the lock. The lock hardware itself stays in place. This is a precise, skilled process and it is not a shortcut; a properly rekeyed lock is just as secure as a brand-new one of the same model. The advantage is speed and cost-efficiency when the hardware itself is still in good condition. If you moved into a rental on Kennedy Boulevard or bought a property in the Bergen Point neighborhood and the deadbolt is a solid Schlage or Kwikset in good working order, rekeying is almost certainly the right call.
A lock change, on the other hand, means the entire lock assembly — cylinder, housing, and all — is removed and replaced with new hardware. This is the appropriate move when the existing lock is worn, has been previously forced, is an outdated design with known vulnerabilities, or simply does not meet the security standard you want. Our technicians work with a wide range of hardware, including mortise locks, which are the style commonly found in older Bayonne rowhouses and multi-family buildings throughout the city. A mortise lock sits inside a pocket cut into the door edge rather than through a bored hole, and it requires a trained hand to remove, service, and reinstall correctly. If your home has mortise lock hardware, do not let anyone who is unfamiliar with that format touch it — improper handling can damage the door itself.
