OEM = 859841 (Injection) - Di-Tech Morini/Piaggio CM
This lock kit includes a cable that acts as an antenna.
This cable is connected and used if you still have one of the original keys and have a broken ignition lock that needs to be replaced.
What you can do is either hang the original key behind the cover at the ignition lock so that the antenna can sense them.
Or hang that key from the old ignition lock together with the new key.
This way the antenna can read the chip in the old key and the moped can be started.
