G8D711S is not alarm system. This is Daytime Running Light module. You can pull out the connector, your front lights won't work when an engine start.
My GV 2002 has a Autostart AS1203 alarm system. There is a description on Internet.
you have to have a memorie saver, plugs into the cigiret lighter spot. then your safe to change out batt without worrie
There is no way of changing 2 press into 1 press. For unlocking all doors - press the remote 2 times.
So you are saying you would replace the alarm system just because you cant find a battery?? thats foolish search online for the battery...there are many interchange numbers so it doesnt have to be a certain brand.
