3. Transponder
If a transponder key is lost;
All transponder keys in the immobilizer control system must be erased. Transponder keys can be ordered via
the "Your proper organization name such as Parts and accessory department" as previously by providing the
mechanical key number.
The mechanical key number is provided on the car pass.
Thereafter, existing and new transponder keys are programmed consecutively using Tech 2. The vehicle can
then no longer be started using lost key.
5 transponder keys can be provided:
Each transponder has different Identifications. If a customer wants more than 2 transponder keys, maximum to
5 transponder keys can be provided by additional programming by Tech 2.
lf a new ignition key with different mechanical key number needs to be installed;
If installation of an ignition lock with a different mechanism key number is necessary (an ignition lock which
belongs to the mechanical key number has to be ordered first), all transponder keys must first be erased and
the two transponder keys which belong to the ignition lock that is now installed must be programmed.
The new mechanical key number must be programmed now into the immobilizer. The mechanical key number
in the car pass is to be changed as well.
