Help with no start

[AdamF]

2016 Hyundai Genesis Coupe, push to start. Had minor accident, Lost key. Had someone come out and get me a new FOB and program it to the car. Keyless entry works, ignition turns on, lights go on, windows roll up and down, but engine will not turn over. Nav comes on, radio comes on and tunes in station but no sound, HVAC controls don't work, wont shift out of park, gauge lights dont come on, and for a split second the dash display reads "system off". Immobilizer light lights up steady. Brake lights work fine. Any help?

Could something have been damaged in the accident? This sounds like a control system not working.

Check the voltage on the battery. I left my glove box open one weekend and it drained the battery. Pretty much same as you described. I jump-started the car and was good.
