Lock Rekeying & Replacement
Moving into a new home, replacing lost keys, or changing who has access? Rekeying changes the key that operates a compatible lock while keeping the existing hardware. If your locks are worn, damaged, or no longer meet your needs, we can replace them.
We assess your existing locks and explain the rekeying or replacement options, helping you choose a practical solution for your home.

Lock Repair & New Installation
We repair residential door locks and install replacement locks, deadbolts, and electronic locks. If a lock sticks, a key does not turn, or a door will not secure properly, tell us what is happening so we can assess the issue at your home.
For new installations, share the type of door and hardware you would like. Equipment compatibility and the condition of the door affect the work required.
