How to use your Vespa GTS Brown Master Key
Modern Vespa Scooters come equipped with an immobilizer system. Without the correct key, you cannot start the engine.
Your Vespa GTS will originally have been supplied with two keys. 1 x a Brown Master Key , and 1 x a Blue Service Key. The blue key is actually for everyday use. The Brown Master Key should be stored somewhere safe. If you lose your blue Vespa key the Brown Master Key can be used to program a new blue key to the immobilizer system.
If you have lost all your Vespa GTS keys, including the brown Vespa master key, it is no longer the problem it once was. Here at www.gtmotoparts.com we can now create and program a new Master Key for you. We sell that key programming service here on our website.
If you still have your Vespa Brown Master Key, then all you need to do is buy a replacement blue key, and then get it cut to match your Master Key. Then follow the steps in the following articles:
