i have a 2000 cadillac deville an d the security systrm will not let it start up what can i do to get this car to start
Check your owner's manual if you have one. I have a '93 and it tells you to wait about 5 minutes and then try again. Not sure about a 2000's diagnostics but you may have to have a dealer reset it. The 5 min waiting period prevents someone from just tampering with the ignition and trying to start the car without a pass key. It resets itself after the 5 minute wait.
