Common patio door lock problems
Handle spinning freely
A loose or broken spindle inside the handle mechanism. The lock cylinder may still function, but the handle cannot engage the lock points.
Lock won't engage at all
Multi-point locks can fail when one or more locking points become misaligned or the gearbox fails. This leaves your patio door unsecured.
Key won't turn smoothly
Worn cylinders, debris in the keyway, or internal mechanism failure can make keys difficult to turn or remove.
Security compromised
After a break-in attempt or if your lock is outdated, upgrading to an anti-snap or anti-bump cylinder is strongly recommended.
