My latest Vespa issue - The ignition won't go into the "Lock" position. The "Off" and "On" positions work as they should (and the scooter runs). I just have no way to "Lock" the glove or seat anymore. When recently unassembling/reassembling, the immobilizer came off, but I put it back on and all seemed to be fine. Why would the lock set now not go into the "Lock" position... I feel like I didn't mess with the ignition/lock assembly at all. I've tried moving the handlebars all the way to the left (and everywhere between far most left and the center) and also all the way to the right, just for good measure. I tried a bit of silicone on the key. Still, the ignition won't "Lock". Any thoughts? Thanks again.
