If you have a backup key try that, other wise you will have to have the key programmed at the dealer.

My 92 Cadillac Eldorado security light is on and starting disabled due to theft system I replaced the ignition cylinder and had new keys made by GM dealer and still will not start still displays same...

A quick fix would be to remove the security systems fuse, disabling it. Assuming this was the only problem and your alright without the security system this is a workable fix.

Theft deterent wont crank on my 2001 cadillac eldorado

The antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Replace the starter on 1996 cadillac fully charge battery, but will not start

Sometimes the security system can shut off your starter. Other times, a new starter does not match up with the correct frequency of the security system and can cause a starter failure. Read up on this site. Check to see if the security light is on.

Car starts, runs for 10 to 15 seconds and shuts of, dash read out says security problem , engine may not start ! I have a 1998 cadillac eldorado ! remote control only works on opening trunk trunk. also...

What you will need to do is get the theft deterrent codes read.This will help in finding the problem.You will probably have a B 2960.The problem is usually the ignition lock cylinder.This reads the key and if it sees the correct code it allows fuel to the motor.What usually happens is the wires break from the ignition cylinder being turned on and off all the time.Hope this helps.Good luck.

(1995 Cadillac Eldorado) - Service Engine Soon light is on.

If this problem just started I would try to get a jump on it. It will be easier to track down if the light just started coming on. Otherwise other problems may come into play and the mechanic will need longer to sort them out. At around 70.00hr.Cheapest fix is to try and drop in a set of plugs. Good luck.
