I would imagine that deploying the airbag in an accident would upset the cars safety systems a smidge.

It could well be a deliberate thing to stop you driving an unsafe vehicle (generally an airbag deployment will write off a car) so as suggested, get the fault codes interrogated as a start point.

Perhaps try to get a hold of a code reader and see what fault codes are stored in the car's computer...

Jump starting might be worth a try...

How old is your battery? How did you test for charge? Modern batteries tend to die suddenly - starting the engine one minute and doing what you describe a few minutes later. A voltage test may show good voltage, and it may be enough to run the radio or some of the lights, but the battery may no longer be capable of producing the current needed to turn the starter. Try boosting from another known-good battery or take it to get load-tested. If a boost starts the car, then you know it is the battery. Of course after your accident, you may have short causing battery drain, or the car's logic may (just a guess) not allow more than a certain number of starts with a deployed air bag. Cars are too smart these days.

Hey guys so I got into a small fender bender with my 06 mini Cooper that has 134,000 miles on it and it set off the airbag but didn’t really do much damage as far as cosmetics I drove it home about 50 miles and  now it won’t start so change at battery battery good. I get lights and everything but it won’t turn over anyone have any ideas of what might be the issue or I can start to diagnose thanks for your help
