Got a standard P1 Alarm Sigma M30 I think, has anyone had any problems with the alarm going off for no reason it has been fine untill last nigh the stupid thing went off 3 seperate times ???

Cheers

Check what the last trigger was (How to is on the manual I sent you)
Should point you in the right direction for testing / false alarms.

is the car in a garage or outside.

I had a problem in a car with a moth trapped inside when a car headlight came through the garage window the moth would fly towards it and set the alarm off.

took me 2 nights to figure that out.

dunno about you, but the alarm on my p1 is playing up.........on a warm day it takes a good few press to dissarm/arm the bugger on a cold day it works fine..........roll on winter :D:D:D

The Car was in the garage all sems to be ok now though no false alarms at all, I am also having problems with disarming the alarm sometimes it is a little touch and go to whether the car will open. Is there a way to change the pin code on the keypad without knowing the current pin?

Yes there is.
I'll mail it to you once you've signed the offical secret scoobies act 1970.

LOL, Cheers Scooby Towers
