As mentioned in my original post, this car came with a full set of gremlins already installed. Now that the tires are out of the way, let's talk about the locking function. I have to manually lock the driver door from the outside with the key (not the remote), then go to the passenger side, open the door, depress the button and close the door to lock that side. The hatch and gas door don't lock at all. I know the system is pneumatic. What is the most likely source of the problem and will I need to visit the dreaded dealership for a fix?
