I locked my car at a petrol station, and when i went to unlock via the fob it doesn't unlock, i've replaced the batterys in the key fob and it still doesn't work, everytime i unlock the car with the key the alarm goes off and the car won't start, I've tried pressing all the buttons in the car like the red light, the tow hitch and the lock button but i just cant get anything to work, before i locked the car i had a bulb light out and the indicator is not wired in at the moment so i don't know if that has anything to do with it...

At the moment i have no manual and my car is stuck in the middle of a petrol station.......

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
