have a little prob

well this morning i went out to my truck to get a bite to eat and heard my car making a strange noise, well, when i opened my hood my engine shut down. I have a DEI sidewinder alarm w/ remote start on it, so that was supposed to hapin. Well then i started my truck with my keys and shut the door. THen CLUNK...the doors lock themselves. MAN, anyways, now i locked out of my truck and i need my keys back, any help would be appreciated....i would like to get back in my truck without calling a lock smith or breaking my window....thanks.
