Last couple of days both alarms on my gsi have started playing up, if I lock it with the remote key (so standard alarm) it goes off sometimes straight away sometimes after an hour or so but it always goes off.
Again if I lock it with the clifford alarm it will do the same, either go off straight away or after an hour or so.
Also sometimes when lock it with the standard remote key it locks then unlocks again straight away.
I am thinking a door/boot/bonnet sensor but checked them all and seem ok!!
