Question about 2001 Cadillac DeVille
I have a cadillac dhs and my key won't go into the ignition
Good chance that the tumblers in the ignition cylinder has gone bad and the ignition switch needs to be replaced. Your going to have to call a lock smith that is familiar with the pass lock system for the GM products so you can have your cylinder and ignition keys programed to start the car, as the pass lock system is your anti theft engine immobilizer. Good luck and keep me posted, be glad to answer any questions.

SOURCE: 1988 Cadillac DeVille
The 88 Deville is one of many cars made by GM that is using the antitheft system called VATS PASSKEY. (its that little black chip in the key) When this system fails, the car can't get the signal from the chip, so it locks out the starter to prevent theft. The car thinks it's being hot wired, so it shuts down. Look for a light on the dash that says SECURITY or ANTITHEFT. This is proof of a security failure. This might be your problem.

You MUST determine ("Due to Check Eng. Light") What the Code / Codes are stored in Computer , as they May Lead us DIRECTLY to the Problem.
Having Said that and with & In my Experience, the Throttle Bodies, AND the EGR Valves Get "CARBONE FILTH " Badly and Block Passages that Are in the "IDLE" Circuit of Throttle Body
side, and In the EGR Valve side of things it causes VACUUM LEAKS @ EGR Valve, This Requires physically Removal of and the Cleaning of these parts by hand. Also the IAC> Idle Air Control Solinoid Can Cause this too Or a Mix of All 3, BUT >>>>>>>>>>>>>>
First thing is I need to know Why Check Engine Light is on that is Determine What Codes Exist On Compter P L E A S E RESPOND BACK TO ME WITH This Information and we can go on from here. I Truely Hope I Can Be of Good Help to you. Waiting for Your RESPONSE.
