REMOTE UNIT, CODING AND ERASING


Coding

On vehicles with remote-control central locking, every new or non-encoded remote unit must first be re-coded for the central locking system control module.


- Switch ignition on and leave key in ignition.

- Use second key to lock vehicle at driver's side door.

- On remote unit, press "Open" button once. Short horn signal will sound.

Notes:
^ The "Open" button is pressed once for programming the first, or a single, remote unit.
^ When programming additional remote units for the second, third or fourth memory addresses, press the "Open" button two, three or four times, in one-second intervals.
^ For example, to program the second remote unit: press the "Open" button once, wait 7 second, then press again.

- After 6 seconds, press "Open" button once (to activate coding process).

The remote unit will now be coded, and it can be used to unlock the central locking system.

- Switch ignition off.

Note: The key must be removed from the ignition before the remote unit can be used to lock the vehicle.

The coding process can be repeated up to 4 times for additional remote units. After coding each remote unit, the ignition must be switched off.


Erasing

Note: It is possible to erase the memory, e.g. if the customer has lost a remote unit. Proceed as follows.

- Use key to switch ignition on.

- Use second key to lock vehicle at driver's side door.

- On remote unit, press "Open" button 5 times in one-second intervals.

Short horn signal will sound

- After 6 seconds, press "Open" button once to activate memory erasing process.

Memory is now erased, and the central locking system can no longer be operated by the remote unit.

- Switch ignition off.
