360 Alarm

I own a 2002 360. Sometimes the alarm cherps one time to lock and twice to open. Sometimes it does nothing other than blink once and twice to open/close but no cherps. Am I doing something wrong as somedays it cherps and somedays it does not. Any help is appreciated to do it correctly to make it cherp while opening and closing.

sounds like the siren battery or siren circuit board is going bad...common on 360's

Where do I find the circuit boad and is it eat to replace. The car is still under warranty, should I just take it in or is it that east to replace that I should just do it myself?

I can't type for crap. Is it easy to replace?

Take it in..

it's difficult to find and replace if under warranty, the entire trunk liner must come out...I'll post pics tommorow.
