Service theft deterrent system
I lost the only key I had, went and bought new key followed
direction to re program and did not work now dash says
"service theft deterrent system" so how do I fix that
problem so I can try to program new key again...?
To program new keys yourself you must have a key that already works. You need to be towed to your local Chevy Dealer to have your new key(s)/programmed to your truck! HTH. -Jim
