Just picked up a 2017 Honda accord lx from a car lot (67,000 miles). Didn’t come with a door key. Went to get a fob and turns out I don’t have any power going to my obd2 sensor, so I can’t get one yet. I’ve looked it up online it says a possible blown fuse or ECU issue. Can anyone give me some advice on what to do next (not mechanically inclined) I just don’t want to be hosed at the mechanics shop to get this fixed
