Is your driver side door lock not working? It is most likely the door lock actuator not working. This is for the drivers side rear door with factory burglar alarm. If you are not sure leave us the last 8 of your VIN at checkout.
If you have had issues with the alarm system going off on it's own, the main reason is the rear door locks for the backseat passengers, Ordered a new one from Med Center Mazda for the left side rear door. Delivery was 2 days after I ordered it, Now if they have a dash pad cover for the front passenger side of the dash I wil be thrilled.
