Hi all i have a problem with my alarm/locking on my mgf, it wont always lock with the key but it always locks with the key fob also when its locked with the fob now and again the alarm goes off ,could connecting it to the t4 diagnostic tell me whats wrong with the alarm and locking with the key. ps when locking with the key it makes a machine gun noise and then unlocks but not all of the time some times it locks ok with the key. sorry its a bit long winded.
