,how can i fix my piaggio xevo 400(2007)?

Hi,

You have two choices:
First, contact Piaggio (dealer) with proof of ownership and serial number of ignition switch (should be stamped on keyslot), or sometimes registration number and frame number. They can supply keys in some cases.
Or, buy new ignition switch, new seat lock and new fuel tank cap (all use same key) and hope there is no imobiliser in the key. (the dealer can help with information about any imobiliser).
