Continue pushing button '1' until you see an icon that looks like a key with a check mark, and the word 'Set' and a lock symbol beneath it. Press button '2' located left of button '1' in the turn indicator stalk to confirm your selection of the lock symbol.
2. Push button '1' lightly and repeatedly to toggle through the display until you see a key with a check mark displayed, and underneath a lock symbol with the letter 'A' next to it, and a clock symbol representing time next to the 'A.' The 'A' stands for 'automatic.' Press button '2' to confirm your selection of the automatic lock setting.
3. Push button '1' to select the clock symbol with the word 'On' next to it. This activates the central locking system, which automatically locks your BMW if a door has not been opened for some time.
