are there known problems????
I have had no problems, all of a sudden it stopped working, the moters sound like they are jamming.

Is it attempting to work but not working?

Make sure your doors are closed.... If they are which they probably are... Make sure the little switch which is pressed when the door is closed is still working on all 4 doors.. If that doesn't work, the car thinks the door is open and wont lock it..

Yeah make sure all the doors are closed and the boot...... otherwise i've not heard of this problem before

yea everything is closed, they make a noise like they atre trying to work but are locked

Try spraying the switches with a little switch cleaner spray, available from your local electronics outlet :D

its not the switches though

now! not a common problem here. Is it remote locking or key?

its running off my alarm, but if i press the button inside the car to unlock or lock the dors they dont work either, just make bad noises

I think you are going to have to do some investigating mate. Maybe one of the door lock actuators is seized which would cause all not to work or maybe the contol box or relay (which i think is in the passenger footwell) is faulty

Well I had a play round and removed some plugs from the alarm main unit as it turns out th alarm is causing the problem.

Well done mate

I'll know more thisafternoon as Im going down to the place that put it in,

Well its all fixed, they just replaced the main control unit
