Do you mean stiff or just not working remotely or on central locking. More info required on what happens to other door locks when using remote or manual key.

Passenger door problems are a classic symptom of boot loom problems. See http://www.zroadster.net/forum/viewtopi ... 18&t=34807

The passenger door lock will lock using the key in the passenger door, but not central locking or remote. The physical locking with the key in the passenger door is much stiffer than using the key the driver's side.
How about linkages in the door being dry?

That's a possibility and one I tried when I had my problems. I squirted WD40 down the door push button and in through the lock - at one stage I thought that was it but it ended up being the dreaded boot loom.
I have never done it but I think you need the door card out to fully lubricate - others have better experience to comment and advise. See http://www.zroadster.net/forum/viewtopi ... 18&t=11887

Before you go to removing the door card, you can access the lock via a small oval shape rubber grommet on the edge of the door adjacent to the door lock...remove it, and give a good spray of lube through there....then manually lock / unlock the mechanism with your key a few times and feel if it has loosened up...if it feels loose,try the remote locking with the central locking circuit...if it works, all good and well, if not, you may have to remove the door card and test the circuit to that lock and proceed from there. :wink:

Anything that works for you....
I don't think my problem is the loom cuz when it's acting up and I press the remote - I feel slight movement in the button.

Very good idea, should be done a couple of times a year :)
