Blocking the unlocking of rear doors from inside the vehicle (Opel Frontera B)

Move the locking lever upward, and the rear door of the car cannot be opened from the inside. To open the rear door in this locking position, use the outside door handle.

The door lock helps prevent accidental door opening, especially when there are small children in the back seat. Door lock safety devices are installed on each rear door.

If the door lock lock is in the "unlocked" position, the rear door lock does not function.
