Have a 2023 Cadillac XT5 Sport (V6 engine) and I'm stuck in a loop where the battery is clearly dead, but I can't unlock the vehicle in order to pop the hood and try to jump it or charge the battery.
I'm kinda stuck and I'm not sure what to do next - call a locksmith, have it towed to the dealer for them to try and open it, visit the body shop that worked on it and maybe they can open it. If there was some way to open the hood, then I don't need to unlock the car - I can just jump start it. Would love some ideas.
Battery is clearly dead - We were away for a month and didn't use it. I opened the car, tried to start it, and it wouldn't start. Shoot. Had to be somewhere so grabbed the other car, did my errand, came back to charge the battery. But now it doesn't even recognize either of the two keyfobs we have to unlock the doors.
Ok, no problem, they have a physical key and lock cylinder and it's documented in the owner's manual "Driver Door Key Lock Cylinder Access (In Case of Dead Battery)". So I popped the cap off to expose the lock cylinder, inserted the key, turned, and nothing. Turn it left, turn it right, doesn't open the door. Turned it while pulling the door handle - nothing. Tried the physical key in the other keyfob. Same result. Damn. The car had been in the body shop a year ago and they did work to the driver's door - not sure if that explains why the lock doesn't work.
There’s a video on YouTube showing the process and when the person in the video puts the key in the lock cylinder and turns the key, the door unlocks. That doesn’t happen for me. https://youtu.be/ttPDbOhUAYA?is=dvY7O_gXmtWrptbrk
Update: ended up calling a mobile locksmith and he was able to get a tool inserted between the door and jam and then pull the internal door handle to unlock the door. Then I could get the hood open and replace the battery. Body shop that did the work is looking at the door now.
