When the ignition system is not encrypted, any key will start the engine but limited to 2000 rpm. The
keys can only be recognised if the control unit has been programmed properly. The data storage pro-
cedure for a previously not programmed control unit provides for the recognition of the master as the
first key to be stored to memory: this becomes particularly important because it is the only key that
enables the control unit to be wiped clean and reprogrammed for the memorisation of the service keys.
The master and service keys must be used to code the system as follows:
- Insert the Master key, turn it to «ON» and keep this position for two seconds (lower and upper limits
1 to 3 seconds).
- Insert the service key and turn it to «ON» for 2 seconds.
- If you have copies of the key, repeat the operation with each key.
- Insert the MASTER key again and turn it to «ON» for 2 seconds.
