Need help!

Well heres the story, I've had my battery disconnected for the past 6 months i havent been driving my car, I just reconnected it and now the alarm does not work...............and nither does my head unit ( except the preset numbers are lit up) my car already had the alarm and stereo installed when I bought it. I was thinking maybe a fuse blew or something..............what fuse or relay goes to the stereo? any other ideas? my car does not lock w/ out the alarm so I need ideas asap (please). also my fuel filler door stayed locked, is there a way to manually unlock it?
thanks, pete

you probably have to re-activate the alarm, similar to entering the activation code into the headunit.

It would be a combination of buttons pressed on the keypad. the dealer will be able to give you this information.
