BodybyFisher Posted February 14, 2011 Report Share Posted February 14, 2011 Try cleaning the key, and using WD40 on the key and sliding it in and out, the contacts in the lock cylinder may be dirty along with the key Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

johnnyjaws Posted February 18, 2011 Author Report Share Posted February 18, 2011 why is that? Link to comment Share on other sites More sharing options...
Göran W Posted February 19, 2011 Report Share Posted February 19, 2011 The Passkey II-system (which a asume you have) is based on the resistance in the pellet and paired with the computer. There is about 15 diffrent pellets and that gives poor odds for them to work by chance. As an alternative you can switch back to the computer that came with the car if everything else is a match!? As far as I know there is no way to reprogram the computer to another keypellet? Link to comment Share on other sites More sharing options...
