What Home Lock Rekeying Actually Does to Your Locks
Every pin-tumbler lock — including the door knob lock on your side entrance and the deadbolt on your front door — contains a set of tiny metal pins cut to match one specific key. When a locksmith rekeys a lock, they disassemble the cylinder, replace those pins with a new combination, and reassemble everything so only a newly cut key operates it. Your existing hardware stays in place. The door frame is untouched. There is no drilling, no new bolt hole, and no damage to the finish on a mortise lock or standard deadbolt. The result is mechanically identical security on the same hardware, but every copy of the previous key now does nothing.
This is why rekeying is the preferred first step after any change of occupancy — not because it cuts corners on security, but because it is the smarter, targeted solution for the specific threat you are facing. If the lock itself is worn, outdated, or a lower-security grade than you want, our technicians will recommend a full lock replacement at that point and walk you through the hardware options before any work begins. But in the majority of move-in and tenant-change situations, the existing locks are mechanically sound and rekeying alone closes the key-control gap completely.
