Alarm again - sorry

[lrussell5]

I know I'm pestering but I've got another problem, although should be easier to fix. How do I de-sensitize the vibration sensor? All of a sudden it's getting set off by the friggin lawnmower of all things at up to 6 feet away. Pain because they're parked next to each other.
ps..thanks Duncan for the tip yesterday. played with the pass door window switch unit and fixed the other bug
