My original locking gas cap had been sticking. To the point that the key would start to bend. I even tried to lubricate the cap through the key hole. That did not work because one of the o-rings had broken and was jamming the mechanism. To take the cap apart, you remove the small roll pin on the end. When you do, you then get to play, hunt the little parts that just flew across the garage. Clean the mechanism, assemble with a little lube and your cap will now work easily. Of course there are two other options, by a replacement N.O.S. cap from your favorite DeLorean Service center or buy a non stock cap.
