So get this. All of a sudden, my drivers door wont lock or unlock. Which, well, it's okay because at least I can open and close my door; but I can't lock it.

It's not my alarm mechanism, I checked that. There's 3 (I think) linkages. One goes from the handle and is then screwed together (tightly) to another linkage which goes down to the door itself and one goes to the motor.

Well, even using the key, the linkage that goes to the LOCK to turn it to make it lock or unlock, binds up and can't turn. I took it off and looked at it, sprayed WD40 in the lock and everything and it just wont turn.

It's almost like the lock siezed up.
So, before I go take it to Acura and pay out my ass for a new one, what else should I try?

Any help is appreciated.
