I have a 96 cobra and am having a bit of a problem and I believe it is with PATS. I lost the main keys so I called a locksmith to cut me some new ones. Got that done and tried to do the manual program of the keys (insert key, wait 45 min for theft light to stop flashing etc.) That doesnt work tho because the theft light only flashes rapidly for roughly a minute and does not display any codes after that either. I had another locksmith come that said they could use a computer to program new keys. He said he was able to see the previous keys that were programmed and he was able to clear them to program the new ones BUT he wasnt able to do this because it would not recognize the new keys for programming. He suggested it was a bad pats antenna. So i replaced the pats antenna with a new one and the theft light is still flashing rapidly with no codes. Used a meter to check for breaks in the wiring and all checked out good. I'm thinking my last options are the stealership or a tuner to bypass pats. Any one have any suggestions, I am at a loss for words now.
