156 alarm/immobiliser reset? help!
so the other day i go to get in my car to go to work and the button on my key fob seems to have stopped working, so i go get my other key and that doesnt work either they wont even pop the boot, so im guessing its not the keys. i can open the doors with the key but as the alarm is is still armed so it goes off for about 10mins and eventually stops. so now i have a car which i can get into but cant start coz the alarm and imobiliser are still armed and i cant turn them off, any ideas?
P.s i have now disconnected the battery for a day and the alarm light is still flashing i guess coz it has a back up battery.
