Vespa lock set for new Vespas with the immobilizer chip. Lock set includes Master Key, Blue Key and 2 tumblers. These will work for most new Vespas including ET4 (2001-2005) LX 150, LXV 150, GT200, GTS, GTV, 300 Super and more. You will only need one tumbler for GT and GTS, so you will have an extra one for a back up.

Note: You will need a fresh CDI to program these keys too. You can NOT program an old CDI box, see 584701 for the LX or ET4, but you will need a new throttle valve GTS-GTV-Super.
