Symptoms of a faulty rear door lock
- Rear door won’t lock/unlock with central locking (or works intermittently).
- Door won’t latch shut properly, or needs slamming to close.
- Door opens from inside/outside unexpectedly (safety issue).
- “Door open” warning stays on (if latch sensor is affected).
- Handle feels loose/heavy due to worn internal mechanism.
Why choose an original-spec part (vs cheap copies)
Better alignment, correct connectors, fewer “doesn’t fit” headaches.
Door locks are high‑cycle parts; original‑spec units typically last longer.
Quality used parts can save up to ~70% vs buying new.
