Who can fix my car?

Not sure if I just need a general mechanic (older car, no warranty), but it just has some warning lights on the dash that aren’t true. They came on after the car sat with a dead battery for a few weeks. We jumped the car and voila, new warning lights (tire pressure, seatbelt, and airbag).

I don’t know shit about cars except the tires are fine (had them professionally checked), so I suspect the other things are fine too, and it’s just a computer or fuse thing. Can a regular mechanic fix those? Anyone have a rec in the Rox/Dorch/JP area?
