If not learned, refer to Immobiliser System Component Programming .

Replacing Keys without Open and Start System

Note:

•

The procedure will first erase all vehicle keys when adding one or more keys. Even when only one key is added all vehicles are erased before learning the new key. The existing keys are relearned again during the programming procedure. Be sure that all existing vehicle keys are available during the programming procedure.

•	This program function will take more than 15 minutes.

•	If the battery voltage is low, charge the battery before programming the control module.
