Disco 2 rear door lock not opening?

If the rear door lock on your Disco 2 isn't opening, it could be due to a faulty actuator or a jammed mechanism. Check if the central locking system is functioning properly and try using the key manually. Inspect the door latch for debris or damage that might be causing it to stick. If these steps don't resolve the issue, you may need to consult a professional for further diagnosis.
