Can I just confirm that if you open the car using the “remote” key, and thereafter open the door without inserting the key into the ignition – then the alarm will not go off. This I contend is how it should be.
I might add that tests on the alarm system by say locking the car with the window down, and then leaning through the window might not always set off the alarm. The principle reason for this is that the internal pressure has not radically changed since arming the alarm, but this would be totally different in a situation where the window was bricked in – or the window was opened by a thief who thereafter lent into the cockpit area.
I should add that for anyone wishing to carry out an alarm test, do remember that the system should be armed and left for 3 or 4 minutes before any experiment takes place. This is so that the system can fully compute the exact conditions when the car was locked and the alarm armed.
Generally speaking I believe the security system to the A2 is very good, its only the stupid sound of the alarm which is a joke.
