Video tutorial

In order to replace the variator of the Sym Mio scooter, you need to loosen the screws that secure the transmission cover panel: this will be located near the rear wheel, on the left side. Once the central screw of the variator has been loosened, you can remove the variator from its seat and also free it from the corresponding belt: the new one can then be inserted and the cover can be closed by tightening the screws, making sure that everything works correctly after installation.

Vespa Immobiliser: How to Transfer the Chip from the Old Key

In the case shown in the video, the new keys are not recognised by the ECU: the Vespa starts but does not run (thus the immobiliser is active). The solution shown in the video involves locating the immobiliser chip in the old key (the one recognised by the ECU). Open the cover on the key (only red master keys or some blue ones), remove the chip (which is a small black cylinder or rectangle), insert it into the new key in place of the new one, and try to start. Now the key will work. If the master key is red, it will definitely work. If it is blue, it might work: you need to cut the silicone; this is possible but a delicate operation. If it is a black clone key, then it is a system that does not work.
