I have a 2003 GMC Yukon XL 5.3 vortec. The anti theft deterrent light is on on the dash board it stays on solid does not blink and the Yukon will not start or turn over. Is there a way to reset this device so my Yukon will start. Have been trying everything This problem just happened after I had the transmission rebuilt and put back in went to start and that's when the theft deterrent light stayed on.
I did try a sequence where u turn key on for 10 minutes but still no response. I was all told by someone I would have to replace the ignition lock cylinder and have the key programmed by a dealer is this a possible fix.
have the same problem?
