Based on the Second Condition following logic is used to control locking and unlocking of driver door.

• If Driver and Advanced key are inside the car and when Door hits the car side frame the Button inside the car is pressed to lock the door and to prevent alarm ring when closing the vehicle from inside.

• If door is opened and not in touch with Vehicle side frames the alarm doesn’t ring
