Hey, y'all. I bought my 300D about a year ago and I'm learning to work on it.

I searched the forum and found lots of posts about door locks, but not one with my problem.

So about a month ago, the striker plate insert on the driver's door broke (that little plastic tab) so I replaced that and as a result had to adjust the shims to get the door to shut properly.

So then the door was shutting perfectly but the next morning I realized that NONE of the door locks will move at all, manually OR via the vacuum system. All of the lock pegs are in the up/unlocked position and I can't push any of them down from the inside, or from the outside with the key or any other combo of inside/outside/key/push. They won't move. The driver's door key will go in the lock, but it won't turn. I live out in the country and am not too worried about car thieves but I do get nervous when I'm out at night by myself and can't lock the doors.

Any ideas on how I might have broken the locks while fixing the striker plate? I didn't mess with the lock or handle at all.
