I'm interested in this because I have locked my keys in my car when I didn't have a spare FOB with me. (hey, with fobs that cost hundreds of dollars, it's not like we all have them taped underneath our frames).
Anyway, what do you mean by "remove any other door lock cap?" Remove what? There is only one key hole which is driver side. Do you mean to pull out the entire lock assembly? I can't think you mean that as whenever I see this done on a broken in car it is a pretty abusive event that bends the sheet metal.
Just wondering. In my case, I had left the sunroof cracked and was able to assemble a concoction with a fishing pole, plastic fork and metal knife that let me unlock the door. We first tried pushing the "unlock" button but after several attempts realized this button was disabled when the car was off.
