Celica 1998 alarm problems (newbie)

Hi there....my car alarm is playing up, ive got a toyota celica 1.8 sr 1998, and my car alarm keeps going off, its just recently started happening, its a factory fitted alarm. any ideas about what i should do?

Thanks in advance.

first off....put your font back to normal size so we dont all get head aches from reading your posts.

Secondly, do you have your user manual? If so read under the alarm section on how to reset the alarm...otherwise take it to toyota and bit the 1 hour labour cost.
