I can't figure out what the code is on my drivers door, where would the 5 numbers be located, I tried the lid, I haven't any clue where at on the enoumous lid...and I heard the code its taped on top the computer Module behind the passenger side kickpanel? I don't have the warranty cards or anything I just have the manual, no numbers, its a 1990 TC Signature

look on the frame of the trunk lid hinge

According the factory book.. look in the trunk at the back of the rear seat. there should be several modules.. the one you want is about size of the large packages of multi stick (20+) packs of gum... on it should be a label with the code from the factory on it. If it is still the original then the doors unlock. At least that is how I found mine for my 90 conti exec series,..
