I have completed this repair on my own, and about 4 customers vehicles, it does happen often.
what the problem is the chip that is in the key is worn I did know that the Gm key with the chip in it is measured by resistants' it goes up too 15 well to solve this problem I purchase a small resistor and plug it into the wire that runs up too the key switch . the resistor has too be the same as the old key bottom line I eliminated the anti theft system on mine.
