Hello,

It sounds as though the trunk lock itself has failed mechanically. From what you have stated it sounds like the trunk lid will not shut. You also stated you can work the lock itself mechanically? I assume you mean by flipping the latch with your fingers. I understand the top and central locking is not working.

These are all related to the trunk lock, linkage, and actuator. Obviously the top does not work because of the trunk problem. As far as the central locking is concerned it will also fail to operate if there is a missing or incorrect signal from either the doors,trunk, radio, or hood. Being that the trunk physically will not shut I would first start with that.

The lock assembly may be just worn out. One other thing to check is that the metal around the lock is not bent or cracked. This can cause the lock to be miss aligned and latch properly.

Hello.

There is a lock rod that connects the lock to the key cylinder and another that connects to the actuator.

You can remove the inner trunk panel to check to see if these have come off. It is common for the retainer clips to break.

As far as the locks go -they are not working because a signal such as a door,hood,or trunk lid id perceived as open.

I would get the trunk lid working first as it may also be the problem with the remote function.
