Sliding Door Lock Replacement

When a sliding door lock has worn past the point of repair, we replace the full mortise lock and strike set with a properly fitted match, and can recommend an upgraded security option if you want more than the original hardware offered.

Signs you need sliding door lock replacement

  • Internal lock parts are broken, stripped, or missing
  • Lock has been pried, forced, or tampered with
  • Replacement parts for the existing lock are no longer available
  • Door has no functioning secondary lock or security pin
  • You're upgrading hardware as part of a renovation

Our process

We measure your existing mortise pocket and handle set, source a properly fitted replacement lock, and install and key it to match your preference. The strike plate is reset to the door's exact resting position so the new lock engages smoothly on the first try.
