OK so I have a few questions for you.

A year ago I had the same problem...alarm came on randomly and I had to pull the fuze. Then, at some point it stopped but in hindsight I think my alarm went "dead" as not even the PANIC button will activate the alarm anymore and I feel uncomfortable without a car alarm!
So, now I'm wondering is it my batteries or a dead alarm?
How do I find out? Is it hard to located and take apart?
I'm at a loss here as I have no clue about alarm system!

Thanks,
Nick
