I presume you have no manual key lock on the door, it's all electronic. The dealer will suggest towing it in but that's not only expensive but time consuming. One way to get power to your electronics is to jack up the car and hook up a battery pack to the positive starter cable and ground to the chassis, that should let you use your keypad. (you could also attach a trickle charger this way but then you'd have to wait a while.) Good luck.
