Pin tumbler mechanism offers familiar, reliable operation without complex electronics.

DIY friendly installation under five minutes with common tools and clear guidance.

The Catch

Frame thickness compatibility: thick jambs may require modification to sit flush.

Inward-swinging doors only; not suitable for outward-swing or sliding doors.

Unlocking is interior-only; cannot be used to enter from outside if locked.

Possibility of accidental lock if installed too low around pets/children; install higher.

Exposed metal hardware may clash with certain door aesthetics.
