Lots of folks here would like to help. You appear to be in a bad situation for which there are few easy solutions.

You can pop the hood by feeding a jumper pack through the front tow hook cover to energize the frunk latch, but if the doors stay stubborn, a https://royallocksmithfl.com/ helped me once by opening the door without damaging anything and cutting a new emergency key on the spot. It was quicker than waiting on the dealer and saved me a headache after a long trip.
