Technically you don't. You may be able to have the lock cylinder replaced and a new key cut at the dealer from the VIN number.
The new key has to match the old chip.

SOURCE: 2001 Cadillac Deville Security System

I had a similar problem intermittent NO START. No click, buzz or other noise. Everything worked but wouldn't start. Unfortunately it took two trips to the dealer to locate the problem. Next time it happens find the purple wire in the wire harness under the cover on top of the engine. A simple tester that connects to ground with an lighted "awl" type probe will tell you if there is power from the key to that point. If there is and you're not starting then the only other thing downline is the starter. Can't repair them only replace. Dealer will be about 900.00 P&L , If you're daring or have some help it's right on top DIY 400.00.

SOURCE: 2001 cadillac deville, overheats without loss of coolant

First, provided their are no visible coolant leaks and/or loss of coolant with no signs of leaks, I would thoroughly flush cooling system and replace coolant, then check and/or replace thermostat (you can place thermostat in boiling water to check for proper function), if you have tried these 2 steps and still are experiencing overheating you may need to replace your water pump which can be a tricky job if you're unfamiliar and try to do it yourself, however, I could walk you through it if necessary. Also visually check your radiator hoses for bulges, wear ,etc along with heater hoses etc. You may want to also check radiator fins to see if they are dirty/obstructed and clean if necessary. Let me know if I can assist you further and how it works out

SOURCE: 2001 Cadillac Deville won't stay on after turning

EIther the IAC or throttle postion sensor is dirty or faulty. Or leaky vacuum hose somewhere. As long as it is not missing and running weird, then you may have bad coil packs.
You can go to autozone.com and register for free online repair manual for your vehicles if you need it.

SOURCE: cadillac seville won't start

I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)

2001 CADILLAC DEVILLE HOW TO BYPASS THE ANTI THEFT SYSTEM


You can't bypass the entire system. It has to remain operational, however you can bypass the most common failure item.
could try bypasssing fuel relay You bridge connections on relay if i remember right.

The most common failure in these is the sensor in the ignition lock that reads the key pellet. That would mean replacing the ignition lock with a sensor included.

That sensor can be bypassed. You would need a digital ohmeter to measure the resistance of the pellet in the key. Now go to Radio Shack and buy a resister of the exact same value as the key pellet. Go to the base of the steering column and locate the two thin white wires that go up to the sensor. Cut the two wires and solder the resister between the two ends coming from the harness. This will permanently bypass the sensor but not the rest of the system.

1998 cadillac deville wont start cause starting disable remove key message shows up. What can i do to to fix it


First try another key if you have one.
If that doesn't work then remove the negative wire, wait a few minutes, reconnect and try.
If that doesn't work then you might have broken cable to the ignition switch.

My 1998 cadillac deville wont start when i turn the key. Starting disable remove key shows up. What can i do to fix it


You likely have a faulty ignition lock cylinder or a problem with the body control module. For some reason, the vehicle thinks it's being stolen and has disabled the starter and the fuel system.

You can bypass the antitheft system, this will be easier and ALOT more permanent. After bypassing, this will never happen again and you dont need to worry about the airbag. PS. Airbag wires are bright yellow on GM.

Someone try to steal my 2000 deville and messed the ignition up ,i went to the junkyard and replaced the ignition with the key and now my car won,t start


The cadillac has a factory security system that has been triggered. You will have to take it to a Cadillac dealership to have it repaired. Or you could bypass the system with an aftermarket product. There is a company called newrockies. Look them up on the internet to find out more about their product.

The resistor chip in the key may be damaged or the sensor in the ignition may be damaged. You can have the ignition replaced or disable the theft deterent by hard wiring in the proper resistors. Search the cadillac forums for details on how to do this.
