FAQ
Questions about Deadbolts & Lock Cylinders
My key sticks in the deadbolt - repair or replace?
A sticky key usually means a worn cylinder or misaligned strike. Cylinder replacement or strike adjustment is a quick, inexpensive fix. We recommend full lock replacement only when the bolt mechanism itself has failed.
Should I rekey or replace my locks after moving into a new home?
If the existing deadbolts are good quality, rekeying or swapping the cylinders is cheaper and just as secure - it invalidates all old keys. We replace the hardware only when the locks are worn or low-grade.
Can you upgrade my deadbolt to a higher security grade?
Yes. We install Grade 1 and Grade 2 deadbolts with reinforced strike plates and longer screws into the framing - the strike side is usually the weakest point, not the lock itself.
Do you match new locks to one key for the whole house?
Yes. We can key front, back and side doors alike so a single key operates every lock, which is one of the most requested upgrades during lock replacement.
