Alternatively, a jammed lock may simply need to be lubricated. If your key isn't turning or the handle is stiff to the touch Try applying lubricant to the lock mechanisms and wiggling it back and forth until it feels smooth. If this doesn't solve the issue, try covering the key with the lubricant before sliding it into and out of the lock to loosen up the tumblers inside.
Rust or debris can also hinder the key's movement inside the lock mechanism. Cleaning the keyhole and lock mechanism thoroughly can eliminate these obstructions, allowing the lock to function as it should again.

Damaged or missing components are more serious issues that require a professional to repair. If the lock's cylinder or latch is damaged, you'll need to replace the components. This requires removal of the door's panel, disconnecting the rods and cables, and removing the lock actuator. This is a more complicated repair, but still feasible for novice mechanics.
