I've seen various reasons why the drivers door lock isn't working. Quite a few of the problems was the air line being damaged/cracked to the point where the vacuum pump 'signal' doesn't have the oomph to operate the locking mechanism. Are you quite sure the lock/unlock assembly is the failure point?
