Key will not unlock door - Central locking works fine

[CJF]

The push button on the interior handle of the backseat driver door doesn’t turn with the auto lock. Nor does it really lock or unlock the door manually. Every now and then pushing the button from the inside will lock or unlock the door, but the button itself is pretty sticky. All bars seem to be connected.

You've got the door card removed, or no?

I do - it is removed

Try spraying some white lithium grease into the mechanism, may help the "sticky" feeling. If that doesn't work then you may be looking at the solenoid as mentioned above.

Ok thanks I'll give it a whirl

Hi Al, I am a new 80 owner and am having trouble getting into and out of the vehicle on the driver’s door. The key will not lock or unlock the driver’s door. The central locking mechanism still unlocks and locks the vehicle from the driver’s door however. Any ideas of what this problem may be?

Cheers!

This happened to me on the passenger door, same symptoms, I found that there was a metal bar coming down from the door handle region that was supposed to be pressed into a white plastic grommet, it had somehow slipped out and just needed to be pushed back in.....all is perfect now. Of course I had to take the door panel off to find this, sounds like you are there already.
