Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Private Locking
The private locking function prevents entry to certain areas and functions in the vehicle. The function is only available on the S40 and C70.
The key blade must be taken out of the remote control to activate this function. The function is activated by locking the glove compartment in the normal way using the key blade (turning 0 to 90 degrees) and then continuing to turn (from 90 to 180 degrees). This sets the glove compartment and trunk lid to valet mode and blocks outgoing calls on the phone module (PHM) if installed. On the C70, the ski hatch and the lockable storage compartments are also locked. A text message in the driver information module (DIM) indicates that the lock is active. The trunk lid cannot now be opened using the remote control or lock switches in the doors. The key blade is kept by the customer and the remote control can be handed to valet parking attendants or workshop staff who need access to the vehicle.
There are two lock cylinders by the lock mechanism for the rear seat backrests to ensure the degree of security required. These lock cylinders can be locked or unlocked using the key blade. There is no electrical indication that these locks are locked. The customer must check this themselves.
This function is deactivated by inserting the key blade in the lock cylinder in the glove compartment and turning it back a quarter of a turn (from 180 to 90 degrees). The trunk lid can then be opened using the remote control or central locking button.
