I had a problem with my ignition in the past and the dealer changed the cylinder under warranty.
Since then I lost my key to the car and can't get an answer on what I can do to get one made.
One guy says if I changed the cylinder& the key I can't use the vin number,another guy tells me it wont operate the computer properly.
Does anyone know what I can possibly do?
Can I do this myself by changing the cyl.with a key that matches it .
Or am I SOS !!!!

Welcome to the forum. While I'm not a technical specialist, you will find many here who are!

To help you it would be beneficial to know the year and model of your Cadillac.

I know some keys have the VATS chip and a generic key will not work.

I screwed up on that one!!!!

It's a 96 Caddie Fleetwood Brougham without keys.
Thanks for the headsup!!!

Hello and Welcome:thumbsup:
> 1) Hustle thee and get yourself an Owners Manual and Factory Shop Manuals.
> 2) Here comes the good stuff:
Per the Owner's Manual, the square ignition key has RESISTOR PELLETS which are part of the vehicle's PASS-Key II system.
The round key is for all other locks.
When I got my 1995 Fleetwood Brougham, I got both sets of both keys as well as both electronic fobs, but I wanted spares as well since I sure as hell would some day slam the door with the keys inside as I did once and as my wife did once with the dogs inside our van once.
So I wanted spares to keep inside my wallet and wanted her to keep a set inside her change purse in her pocketbook as well.
It took a week for GM to MAIL the keys to the dealer!
Thus I have to wonder about your locksmith and what his connections were and how he did it.
It seemed Cadillac went to what looked like extreme lengths to prevent some jackleg from getting a key by nefarious means.
Yet, The Owners Manual also states that a QUALIFIED locksmith can make a key by reading the BAR CODE on a key.
But that is furnished on new cars only and I sure didn't have one and I guess you didn't either.
The alternative is the plug, punched out of the key and, like me, yours are also probably long gone.
So, unless others on this BB have a better idea, I wonder if the quickest way to get a key is to go to the nearest dealer or . . .
back to that locksmith ( ? ).

Good luck :alchi:

Go the dealer, they CAN look up your key with the VIN. If they claim they cannot, call Cadillac corp on the 800 number and explain it to them. They are just being lazy. They can make the keys.

My wife ran in to this on a 84 Cavalier and the dealer was not cooperative. She called Chevy direct and they called the dealer and had her talk to them, they gave her the same run around, then the lady from Chevy chimed in and explained it to them. She got a FREE set of keys and sincere appologies. They were just being stubborn.

Chevy Cavaliers had resistor pellets?:confused:

No, they have keys. Just like any other car. GM has full access to all that were ever made. All they need is the VIN.

So the "Resistor Pellet" on the Cadillac ignition key means NOTHING and is there just to fool the customer into thinking he or she has a theft-preventive device? :confused:

Who ever said anything about it? Cadillac has the keys, they have the machine to cut them. The will look up your car by the VIN and it will tell them which key to use (which if you car has a resistor, will have the correct one), it will tell them what settings on the key cutter, and they grind the key and hand it to you.

What issues are you having?????????????????

ANY GM dealer can do this.

COOL IT TOM! :tisk:

Start at the top.
Then read the part where he says he has a 1996 FWB.
I imparted my experience with my 1995.

Sorry, we were having a bad day at the Cad dealer today over crappy work, this is the same situation my wife had years ago. Dealers that refuse to give proper service or do crappy work need to lose the dealership.

I'm going to give the benefit of the doubt to my dealership (NWH, Torrington, CT) since all dealings with them have been quick, courteous, efficient and not all that bad in terms of $$.
If you look at the FSM you'll see the INTERROGATOR (J 35628-A) is used to work with the PASS-Key II system. A friend who is a Certified GM Tech, says that unit is a picky piece of equipment and their dealership has had more than one die on them and had to have replacements.
That may have happened to my dealer. Thus the FAX to GM to get my keys instead of having them made on the spot while their Interrogator was being repaired or replaced.
Thanks for your input.

Check with eWill on here, he is a GM tech too to double check. He can confirm.

Maybe this is the security measure GM put in place in the last year or so because people were able to walk into a dealer and say they lost their key and provide the VIN and get a new key made on the spot. Then they go back and steal the car....

That would make a lot of sense.

Allegedly it is illegal for ANY dealer or anybody else - locksmiths included - to cut a key from only a VIN!
That is supposedly FEDERAL law; a part of the same Federal law that cost me an arm+leg to get a cutout switch for the damn steering wheel air bag in the Stratus since my wife is under 5' tall and sits too close to the steering wheel, even with pedal blocks.
(The first such airbag fatality was in Danbury, CT. Young woman under 5' tall driving in slow, heavy traffic just bumped car in front of her. Airbag went off, stopped her heart, killing her.)

Does anyone know how far back GM can go with the VIN to cut ignition keys?
