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
SO guys I found the answer!!! I went out to My car during the winter months and haven’t drove it in weeks.The check engine and theft lock light was on the car and it would not start.I unplugged the battery negative terminal and adjusted the positive terminal and guess what!!! I reconnected the negative the next morning and the car started.First step is open the door with the key remove battery from key first.Pop your hood and connect the battery while the key is in the ignition.Next,sorry if it’s kind of confusing but this works and I’m ecstatic about solving this issue and saving hell of cash on a battery or wires! Ok, then while the key was in the ignition I turned it to the point just before you crank the car so the system could check everything.The lights went off and I started the freaking car!!! I was scared to turn off the car but I guess doing this reset the warning lights! I have had nothing but problems with this positive cable of the terminal and I believe there is some type of short in it and there should be a recall because these cars are sketchy
Msprincess06 my wuestion is for you. Remove battery from fob before opening door? And do we replace battery before putting key in ignition ?
So i completely unplugged my battery for a couple of hours and then reconnected them to the terminal.Opened the driver door with my key and put the key in the ignition just before the spin over position and watched all the lights go off on the dash.The car started.
