The key fob is stuck in the key holder? As well as other electrical items are not working (Windows, lights)?
Does the engine start?
Have you tried to jump start the vehicle, It sounds like the battery voltage is to low. If that doesn't work I would try a battery reset. Disconnect the black wire off of the battery in the trunk and leave off for 30 minutes and reconnect and see if that helps, This will reset all of the control units in the vehicle.
