Hey GM I have a great idea. I install systems in buildings and the security system can be programed several ways. it appears that the passkey system "FAIL OFF", meaning that if anything goes wrong with the system that it turns the system off. a lot of these cars and trucks are past ten years old and are now at the bottom of there blue book price, Really who is going to steal this old ride with 200k miles. Our systems can be set to fail on, meaning that it knows the time and year in the ECM unit so why not "FAIL ON" when it goes bad, why off. Give us a light the says security fail. The programmer had the option to turn it off or turn it on. all it would do on your 1995+ is let you drive it till you decide to get a new ride or fix the security system.
