Rekeying vs Replacing a Lock: Which One Do You Need?

Here is the difference in one breath: rekeying changes the inside of a lock so old keys stop working and a new key takes over, while replacing swaps the whole lock for new hardware. Rekeying keeps your existing locks and costs less per door; replacing makes sense when the lock is worn, dated, or you want an upgrade.

When rekeying is the right call

Rekeying fits when the locks are in good shape and the real issue is who holds a key. After buying a house, you rarely know how many copies are floating around, so rekeying every entry to one key is a clean reset. It also fits after losing a key or a roommate moving out. If you want one key for several doors, that is a keyed-alike setup, which our residential locksmith team handles in the same visit. Larger properties often move up to a master key system.

When replacing makes more sense

Replace the lock when it sticks, grinds, or has taken damage that lock repair cannot fully fix, or when you are stepping up to stronger hardware. New deadbolts, smart locks, or high-security locks all call for fresh lock installation rather than a rekey.

A simple way to decide

If the hardware is solid and you just need to control keys, rekey. If the lock is failing or you want an upgrade, replace. Not sure? We look at the door and tell you which is the better spend. The same logic applies to a business, and we cover homes across Raleigh, Cary, and Apex.
