Question about 2003 GMC Yukon
Theft light on indicates a problem with passlock. You have a problem
with the key or ignition switch. When I worked I replaced a lot of
ignition switches, so i would say that would be your problem.
Give this a try it might work for you........
When you put the key in ignition, turn it on (not to crank) dos the security light start flashing? If so, you need to either wait 15 minutes or wait with the key on until it stops flashing. Once it stops flashing, try to start again. You should get to try it 2 times before the passlock will lock up again.
