Opening doors

If you can still open the hatch and remote start the car with the fob, the problem may be a Short in the wiring harnesses, which is not mentioned in the manual and must be fixed at the dealership. Not that the manual is much help anyway when it is locked in the car you are unable to open. So at 5 am try calling AAA or maybe a tow company...hard to know since different places have different options. My local police were the guys who helped me in the middle of a rainstorm one night.

Also once you get into the car read the manual to learn how to use the manual key hidden In The fob. The keyhole is under the cap on the right side of the door handle. Slide the key under the cap to pop it off, then insert the key. Putting that cap back on is tricky afterwards so you may want to just keep it in the glove box if this is a recurring problem
