I had this problem and my mechanic took both cables off the battery and touched them together to reset the computer he said. Everything worked just fine after he hooked the battery back up.

I had the same thing happen to me a few years ago, and I think it was a short in the ignition.

I am having the same problem with my 2003 Envoy SLT; did you ever figure out what the problem was?

Hi, we had the very same problem with our 2004 Cadillac SRX. After some research, I removed the security fuse from the fuse box and the problem went away. Somehow the car thought it was being stolen and locked itself up. When I took out that fuse, I could actually feel the car relax. Maybe this will help you.

I had the same thing happen to me a month ago. An 03 Envoy SLT. Mine was my alternator had went out and my battery was being drained; eventually it wouldn't do anything. Got the alternator fixed and battery charged; cranked right up.

My 2002 Envoy does this key stuck in ignition thing also.
