Why a Lock Sticks and When It Needs Repair

Why Locks Stick

Sticking is often caused by door movement, a worn latch, or a misaligned strike plate rather than the lock cylinder alone.

Misalignment vs Wear

Seasonal door movement causes alignment issues; older hardware causes wear. The fix depends on which one you have.

When Lubrication Is Not Enough

Lubrication helps a stiff cylinder, but it will not correct a misaligned door or a worn latch.

Repair or Replace

If the hardware is sound, adjustment or repair is usually the practical fix. Replacement is better when parts are damaged or weak.

When to Call

If a lock no longer secures the door or a key is hard to turn, it is worth having it checked before it fails completely.
