I would like to know if anybody has any information on door lock cylinders. I have a 2002 Celica which has no drivers door cylinder usable to me. Since I bought the car a year ago, I have to open the passenger door to enter the car. My key won't even go into the cylinder in the door. I do have several MKIII door lock cylinders, and I'm wondering if they are the same before tearing into my door to see. None of the local auto stores carry them, rock auto doesn't show any part for the door on either car (I find that odd). I googled toyota parts, and the genuine Toyota parts site would only answer questions instead of showing me parts. I guess I may have to just pull the parts and see, but maybe somebody knows. I would appreciate any information you could give.
