Don't get me wrong but this post is not the greatest guide. I am an expert in the business and I can tell you how to steal any car you want. just send me a message or go to
www.kinut.net but here is some help:
The best way to steal a GM is Photoshop! If you have lost your keys you can go to the Parts department at any GM dealership and tell them your story of how you lost your keys in the lake, they will then ask you to show proof of ownership. Here is where Photoshop comes in, scan your registration or title to the car you actually own and change the details to the car you want. If you cant photoshop very well, do the registration, print, then copy it to make it look like a fax. Then take it to an out-of-town dealership so you can say it was faxed to you. Insurance is the easiest and you should print that out as well just to have as more proof. Once they get the proof they need, they will either call a 1800 # or log into a GM website and enter your vin and their dealer info and gm will fax them your key codes and the proper resistance value. They can cut the key right there and give it to you.
Some dealers will copy your registration with your DL and “put it on file”. Most won’t bother. I had one dealer do that to me on the Doug Rippie Z06 I was going to steal, so I just didn’t bother getting it. I found another Z06 that was a little faster so I tried the same way, they copied it also. So I had the guy behind the counter look up a bunch of other parts for my car and when he walked away I reached over the counter and took it

.
I try not to risk it when I don’t have to, if they did keep that paper with your info I really doubt anything will ever come from it, the car is gone, the owner or dealership will report it to insurance and that’s it for that cars life. If that car was at that dealership they would put 2 and 2 together. I good fake ID would be a great way to do it.
Details on the PASS-Key System
The personal automotive security system (PASS-Key®) is standard equipment on certain GM vehicles. The system is designed to prevent vehicle theft by disabling the engine unless an ignition key with a specific electrical resistance is used in the ignition cylinder. The PASS-Key® system and the content theft deterrent system operate separately.
There are 15 different ignition key resistance values. Of the 15 different resistance values, or key codes available, only one will work with each body control module (BCM). Once the key code is programmed into the BCM, the code is stored in non-volatile memory.
The PASS-Key® system prevents the engine from starting by controlling the theft deterrent relay and the powertrain control module (PCM) fuel enable input. If the PCM does not sense the proper fuel enable signal, fuel will not be provided to the engine.
If the wrong resistance value is sensed when the ignition switch is in the RUN position, the BCM will not ground the theft deterrent relay control circuit and will not provide the fuel enable signal for approximately three minutes. The engine is prevented from starting and discourages a thief from trying key codes or resistance values at random.
If the correct resistance value is sensed when the ignition switch is in the RUN position, the BCM will ground the theft deterrent relay control circuit and enable fuel delivery. The engine will start normally.
If the PASS-Key® system detects an open or short to ground when the ignition switch is in the RUN position, the BCM will default to fail enable mode. Fail enable occurs when the proper key resistance is sensed before the open short to ground occurs. Fail enable will illuminate the security indicator lamp and allow the operator to stop and start the vehicle until the problem is corrected.
The PASS-Key® system includes the following components:
Ignition key
Ignition cylinder
Body control module (BCM)
Theft deterrent relay
Powertrain control module (PCM)
SECURITY indicator
Ignition Key
The ignition key is a typical square ignition key blank with an imbedded resistor. The key blank and resistor are not serviceable separately. There are 15 different resistance values. The ignition key also has mechanical cuts similar to non-PASS-Key® ignition keys.
Ignition Cylinder
The ignition cylinder contains a set of electrical contacts used to measure the resistor in the ignition key. When the ignition key is inserted into the lock cylinder, the resistor in the key makes contact with the electrical contacts inside the ignition cylinder.
Body Control Module
The Body Control Module (BCM) contains the theft deterrent system logic. The BCM reads the key code from the ignition cylinder when the ignition is turned to the START position. If the code is correct, the BCM will enable the theft deterrent relay and will send a fuel enable signal to the PCM via the class 2 serial data circuit.
If the BCM receives the wrong code, the BCM will immediately go into tamper mode. The tamper mode will lock-out the vehicle starter and fuel injectors for 3 minutes. The SECURITY indicator will flash while the BCM is in tamper mode.
Theft Deterrent Relay
The theft deterrent relay is used to prevent the engine from cranking if the correct resistance is not sensed at the ignition key. It prevents the engine from cranking by opening the circuit to the starter solenoid.
Powertrain Control Module
The PCM communicates with the BCM over the Class 2 serial data circuit. When the BCM enters tamper mode, it sends a Class 2 message to the PCM in order to disable the fuel injection system. If the BCM receives the expected ignition code, the BCM sends a class 2 message to the PCM in order to enable the fuel injection system. The PCM then allows the vehicle to start.
SECURITY Indicator
The SECURITY indicator is located on the instrument cluster. The SECURITY indicator is controlled by the BCM via the class 2 serial data circuit.
Most fords now have a PATS(Passive Anti Theft Security) key system. P.A.T.S. was introduced starting with select models in the 1996 model year, F-series 1999, and Super duties in 2008. Duplicate keys can be made only with the Ford NGS computer or if you have the key(s) to the car.
With PATS I, as long as you have at least one working key and can read the owners manual that came with the vehicle, you've got a good shot at programming your new key.
With PATS II, two working keys are required for admittance to the programming show.

Program a pats key
The Ford NGS Computer can be bought by anyone, and is easy to learn. With this you can program the key to work with the car you need. The biggest downfall of this is the computer has a 10 minute delay while programming the key. It’s costly but you can easily pay for it with one car. We first bought ours just to get one car. Buying directly was the cheapest route for a new one. Ebay sells plenty of used ones.

Key-swapping
The main idea here is to have a key in your pocket that looks just like the key to the car your going to get. I’ve never tried this alone, we always had two or more people with us. You go to the dealer and start looking at the car you want and bullshiting with the sales man, he will get the keys so you can look at it, start it up etc.. We always had one guy talking to the salesman under the hood while the other is inside with the car running, the one on the inside switches his key with the original key while it is running by taking the key tag off the original and putting it on his. Then he can kill the ignition and hand the fake key back to the salesman. This works perfect if it has keyless entry on the keychain, then the salesman will lock it up and you can go look at other cars.
It’s harder to do with no keyless entry or just one key because the salesman will try to lock the doors with the fake key and all hell breaks out.
Now all you need is a key that looks like the original! Google it and find out what it looks like, most keys look the same for the entire brand of that car. Go to the gym and dig through the drawer/wall where everyone leaves their keys to find one. Or some dealers leave keys in the cars in the daytime(idiots) but almost every dealer leaves the keys in the cars that are in the showroom floor. Walking through a car dealership you have so many opportunities to snag a set of keys laying around. Or buy a blank from the parts department and have a locksmith cut it any way he wants. Those are a few ways, if those don’t work and you can’t find a set you’re a dumbass.
There were a few times this didn’t work out, we would come back to get the car and the batteries would be gone, the car was moved inside, or the police were there

No big deal, just move on to the next one. But there was one time when we were caught in the act, well sorda.. I wrecked my car and for some reason I thought the guy that hit me(I cut him off) didn’t see my plates so I drove off. Two hours later the police are calling me, I didn’t answer the phone and thought what I should do. I decided to blow off the cops for the day and have a body guy fix it over night, then show the police my car the next day showing it was fine and someone must have stole my plates. The body guy started on it and then realized he wouldn’t be able to do good enough job to pass the police inspection. Next I tried renting an identical car and using its parts on mine for a day, but my car was too new no rental company had one. So I thought I would just steal a car just like mine. I was driving my VW Passat, so we went to a dealership a few hours away and started looking at an identical car to mine. I had my spare key in my pocket ready to swap, swapped them while he was under the hood, killed the engine and locked the car up, then handed him my key. But he wanted to show us how you could stick the key in the door and turn it to roll the windows up and down. Well the key didn’t work and he knew something was up. He said, “this isn’t my key, you have my key give it back” and I told him I didn’t know what he was talking about, we went on for a few minutes until he pulled out his phone and started dialing, then I said I would give it back if he gave me my key back(I needed one key to swap at another dealer) at this point he started yelling for other salesmen and we jumped in our truck as he’s writing down our tags we are haulin’ ass out of there. One car tried to follow us really slick but we noticed and lost them. I was glad we stopped around the corner before going there and put on fake tags. From there we drove to another dealer and got the job done, I was a little shook up but I didn’t want to get charged for that hit and run. Oh by the way, worked perfect, I was a dick and made the cops drive an hour ½ to my house to inspect my car, they did and apologized for the mix up, but gave me a little hell about not noticing my plate missing.
Key-stealing
One day I was so pissed off because I was moving the next day and had just totaled my truck, so I walked in this dealership that had an SRT-10 sitting right up front, and walked around until I found the room where they kept all the keys, looked through all of them until I found that truck key, took it and had someone drop me off there that night. The only reason why I did that was the anger built up inside of me, but we started doing this more and more, it was so easy. Some dealers keep the keys in room by themselves I was really surprised, most are in the managers office, a machine, or the cashiers office.
The best example of this method was when four of us drove 8 hours to get 2 corvettes and couldn’t get either. So on the way home we decided to stop by this other dealership and see what they had. We drove home that night with 3 new cars lol. Eddy test drove a new escalade while the rest of us looked at what else they had. We found 4 other cars we wanted, went into the sales floor and just started talking to the manager, I walked off and went into his office and found 2 sets of keys to the cars we wanted, went to grab them but couldn’t get them off the wall, they locked them to the wall! So I stood there and unscrewed the keys off the key ring, took longer but worked. After Eddy got back from the test drive we all left, I then told him how we got 2 sets of keys and he pulled out the keys to the escalade! The salesman never asked for the keys back, we thought for sure he would have remembered before they left that night. But obviously he never did.
