I would say that the car has to be completely repaired and that includes what is called the SDM. That is the module that controls what goes on in a crash. It has to be programmed to the car.

Right, the SDM is keeping the high voltage contactor from engaging. In a gasser it keeps the fuel pump off.
I don't know if it can be reset or needs to be replaced. Either way, a dealership needs to do it.

I had a problem where my car would not move after a DCFC session.
Dealer followed their 'Trouble Tree' and replaced HPCM 1. Car worked until I DCFC again. Same problem.
2nd thing was to replace the SDM, $800 and not a warranty item. I insisted they do a DCFC before returning it to me.
It failed, but I was still supposed to pay for the SDM that did not fix anything. Something about once it's programmed to the car it can't be reused at all, , BS.
3rd try they replaced the HPCM 2 (the box that deals with DCFC, duhhh...) and the car has been fine for years.

I fussed and cried and called GM. They reduced the price of the repair to $200 for the SDM that didn't need replacing.

Good Luck,
Do you have insurance on the Spark EV?
'14 Spark EV 2LT w/ DCFC. 97k miles !! Going strong!
'17 Bolt Premier w/ It All! 70k miles. Brand New Pack w/Warranty!
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 1st try, nope, 2nd try / cost $800. 3rd try fixed it.

There have been several posts on this site about that. Search for "key" , "fob", or "keyfob".
