First, thank you guys for the replies!

Well I had a friend who had a big easy so he came and opened my drivers door for me. Jumped the car and let it run for an hour. I turned it off, closed the door and walked away. 2 hours later i went out to my car and the damn key fob wouldnt work to get in. I had to call my friend and have him pop the lock again. So now I'm guessing my key fob battery is dead?
So my question is, is there a way to ensure it is you key fob? I mean if the battery is dead would the transponder still work and let you start the car? Is it normal for the key fob to stop working after the cars battery dies? If anybody can think of anything that it might be let me know. Thanks
