Drivers door not locking pasengers will lock

  1. #1
    My drivers side door will not lock at all the push button fob wont lock it, nor will pushing the pin down its just solid. Passenger side will some times lock with the remote but some times not (this could just be the battery in the fob though), it will lock with the key and I can push the pin down from the inside. Not to bothered about central locking but would like the locks to work. Could it just be the solinoid or is there anything else that I should check.
