I purchased a very low mile 2015 Audi Q5 that was in a rather minor front end collision from an insurance auction. I wanted to scan the engine for any error codes before bolting on all the nice, new painted parts... but the car won't go into accessory mode. I realized I hadn't even been able to use the remote for unlocking the doors and I in fact had to pull out the manual key and physically unlock the doors. I can turn on the headlights and stuff, so the car is getting power. I had a company come out and try to re-program the key that came with the Q5 at purchase and a brand new key, but kept getting the following error code.

FAZ1531E
Key assigned to different VIN

Any chance the accident caused a module or relay or fuse somewhere to be damaged, thus preventing the vehicle from picking up the key?
