Disable Antitheft

The key doesn't match what is programmed in the computer. How did it get stolen in the first place if the PATS wasn't disabled by the thief? Did the insurance company just total it out because the column was smashed up?

From what I've heard, that chip in the key is just like a resistor, each one has a diffrent resistance and apparently a good shop that sells remote starters or alarm systems can make up a bypass resistor that fits inside your steering column which will eliminate the need for the chipped key ... might be worth looking into. Another thought that might work is go back to the auto place you got the steering column from and get the Theft Deterant module out of that car (left rear fender well in the trunk) and try using that one instead of yours... just might work :)
