I'm confused reading the last post....
A 'lost in translation' language barrier thing...
On leaving the car:
1 press on the 'lock' button just locks the car.
2 presses on the 'lock' button turns on the 'coming home' lights
as well as locking the car if I remember correctly..
(been a long time since I have used that).
On going to the car:
1 press on the 'unlock' button unlocks the car
2 presses on the 'unlock' button unlocks the car and turns the lights on.
