Registration of new devices
To prevent unauthorized tag registration, entry in the device registration mode is possible only after entry of the unlocking code. For registration of new components the immobilizer should be set to the device registration mode using the unlocking code. The procedure of new device registration is described in the corresponding section of the User Manual.
If the car owner has told you the unlocking code, ask him/her to change it for a new one after completion of new device registration.
