Electronic main key
The electronic main key has an integrated radio
frequency and infrared remote control, plus removable
mechanical key.
The remote control (1) operates all locks on the vehicle.
The mechanical key (2) works only in the driver’s door,
trunk, and storage compartment locks.
When using the mechanical key (2) for lock operations,
it can be removed by sliding it out of the remote control.
To do so, move locking tab (3) to the right and slide the
mechanical key (2) in direction of arrow (4).
The remote control transmitter is located in the
electronic main key.
The infrared receivers are located in the door handles.
Notes:
Remove the mechanical key from the electronic main
key when using valet parking service. To prevent access
to trunk or storage compartments lock them separately
and retain the mechanical key.
See page 38 for separate locking of trunk and page 151
for locking of glove box.
