9.3.4 Learning multiple new keys

• Insert the keys to be learned into the ignition
lock one after the other.
• Turn the key to be learned to position "1".
• Leave the individual keys in the position "1" for
at least 1 sec.
Up to 10 keys can be learned.
With this technique, it is possible to learn one key
on several immobilizers, such as for a general fleet
key.
This function is only available if the
control unit
connected to terminal 30.

9.3.6 Security functions

If more than 5 keys are activated in the ignition
lock within 1 minute with different invalid codes, the
immobilizer remains active for 15 minutes and
accepts no valid keys during this time.
This procedure prevents the "testing" of different
keys and the coincidental locating of the correct
key.
If different invalid keys are recognized without the
ignition lock being brought to position "0," the
immobilizer remains activated for 15 minutes and
accepts no valid keys.
Valid keys are only accepted after the 15 minutes
and recognition of the start switch in the "0"
position. This prevents the key from being tested
without the mechanical
activated, such as if the ignition lock is forcibly
brought to the "1" position.
