Cadillac SRX First Generation Forum - 2004 - 2009 Discussion, Key Stuck in Ignition in Cadillac SRX Forums; I bought a key and programmed it with no problem. Today, I stuck the new key in the ignition to ...
There is a key release hole on the underside of the steering column. It may be protected by a slotted plastic cap. Remove the plastic cap if present and use a pen point to depress the tab while trying to turn the key back to off. That should get the key out.
Try the other key to see if the vehicle still starts after you get the current one out.
Thanks. I located the tab and was able to get the key out. The original key won't start the car either. The theft light goes out, but nothing happens when I try to start it. No clicks, nothing. All the lights are on like it's getting power, but it's been sitting for 2 weeks while we were on vacation, so I'm wondering if the battery is somehow slowly draining. I tried to hook up some jumper cables, but it still wouldn't turn over. I have the battery disconnected now with a battery charger hooked up to it. I'll let it charge for a couple hours and see what happens.
Open the underhood fuse panel. Near the front is a large connector w/ lots of wires. There's a large purple wire there. Jump that to B+ withe key in run and car should start. Drive it and then erase codes, all should be well.
B+ would be the battery positive terminal. You have the symptoms of a failed or failing ecm. I had a similar condition with my CTS last week. Your shifter light is probably off, and your oil life and transmission life probably do not register on the DIC anymore either.
For future readers/searchers, jumping the purple wire to the positive side of the battery woke the car up, thanks Glake89 for that tip. Once it started, it ran well. I did have to erase 2 codes, the 0100 ECM and a 0700 (tranmission something-or-another). The key came out on its own which is a positive. Ternstes, I have my oil and transmission life back, both reading as appropriate (they didn't reset). I also have my fuel needle reading correctly.
I'll keep an eye on the computer and will keep a jumper wire and pen in the back just in case it decides to act up again. I may spring for a $100 junkyard ECM just to have it on hand.
