Alarm/battery help

Right last night on my way back from the curry house my car wouldnt start. I had to leave it alnight there. I've just gone over to try to remove the battery to charge it and my alarm goes off.

So I've had to call the rac they have charged the battery but the bloke thinks its on its way anyway. The problem is I can't change it without the alarm going off.

Does anyone know how I can do it with a sigma m20/30 alarm? There must be some code I can put in surely ?

Thanks

Call the manufacturer and ask?

Can't seem to find an official site for them ?

Fair enough :D

Try these guys Gordy: BATS They're official dealers or summat - should be able to help you http://www.banbury-web.co.uk/caralarm.htm

Cheers I've found the number for the place I bought it so I will give them a ring in the morning :)

what ya do is get another battery and some jump leads.... keeping power to the alarm, while you swap the battery ;)

I've been told how to get into valet mode now :) By some kind person on digi darkroom :)
