ok when i bought the car the guy i bought it from told me that a tow truck driver tried to open the drivers front door with a slim jim and broke something inside the door for the alarm (cant turn off alarm with key). so i took apart the door to look at the lock. now on the end of the door lock cylinder is a small black round thing, held on with a "C" clip which is for the alarm, it was broke apart. i have looked all over the net to find the part or part number but a cant find it and i was wondering if any body here would know the name of it or the part number. thanks

Hmmm having been in there myself, I'm having a little trouble picturing the part you are talking about. Would you happen to have a picture of the offending part?

i dont but if i can get a pic taken i'll try to post it

If I remember correctly it is part of the door lock cylinder. YOu will probably be stuck buying the assmebly from the dealer. Have you called a dealer yet?

Correction to my last post, It might be serviced sep. But I would bet it is a dealer only part. Call a dealer, get the part number then start looking online for the best deal.
