When the ignition system is not encrypted, any key
will start the engine but limited to 2000 rpm. The
keys can only be recognised when the decoder
has been correctly programmed. The procedure
for programming a new decoder requires the rec-
ognition of the "master" key as the first key to be
programmed: this is particularly important as it is
the only key that allows the decoder to be reset
and reprogrammed for programming 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 lim-
its 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.
The maximum time to change keys is 10 seconds.
A maximum of 7 service keys can be programmed
at one time.
It is essential to adhere to the times and the pro-
cedure. If you do not, start again from the begin-
ning. Once the system has been programmed,
master key transponder, decoder and control unit
are strictly matched. With this link established, it is
now possible to encode new service keys, in the
event of losses, replacements, etc. Each new pro-
gramming deletes the previous one so, in order to
add or eliminate keys, you must repeat the proce-
dure using all the keys you intend to keep using.
