I replaced the driver's front door on my 91 245 (it had some damage and I'd found the right color replacement at the junkyard). When I put it all back together the door won't lock neither with the key nor from my pushing the lock button.

When I push the lock button (I do this with the door closed), it doesn't feel like it's stuck, but rather it feels like it should if I was pushing the button while the door was open. (A feature I assume exists to prevent us form locking the keys in the car).

I figure there are two possibilities:
1) The crumby wires on the little collar around the lock cylinder have shorted (the shielding wasn't in great shape, but I've seen much worse).
or
2) There's a way that this collar needs to be indexed somehow to work correctly.

Does anyone have experience with replacing that collar thing? Do I need to make sure it's oriented a certain way? It looked like it would only fit on in one position, but maybe I screwed that up somehow. Or did I do something else completely wrong?

Any thoughts to help prepare me when I pull the door apart again?

Thanks as always!
