Initializing Key-Chain Transmitter
The key-chain transmitter is allocated to the general module in the vehicle by way of initialization.
A maximum of 4 keys can be initialized for each vehicle. The codes of all other keys are deleted when a key is re-initialized. This means that all the keys of a system must be initialized simultaneously.
Procedure
Carry out key transmitter initialization in the vehicle interior.
- Unlock vehicle via central locking and close driver's and passenger's doors.
- Briefly switch on terminal R in vehicle (maximum 5 seconds) and switch off again. => The system is now ready to be initialized.
- Press and hold "unlock" button on the key transmitter.
- Point key transmitter in direction of antenna and, with the "unlock" button pressed, press "lock" button three times within 10 seconds. => A new code is generated in the key.
- Release both buttons. => The general module signals that initialization of the key transmitter was successful by locking and unlocking the central locking system.
Repeat the procedure as of Point 3 (= press and hold "unlock" button on key transmitter) to initialize the other keys. Terminal R must not be varied during this procedure.
The initialization procedure is terminated if terminal R is switched on.
