I searched the forum on this topic and learned that JimH is the expert on this topic. So I tried to get in touch with him - the website does not seem to work. I left a voicemail on the phone number I found, but haven't heard back and also sent him an email. I realize the recommendations of the forums date way back, so things change.
That said, I will have to explain my situation:
My husband had bought a brand new Piaggio Vespa GTS 300 2020 and cared for it like it was a baby. Shockingly, he died of a heart attack suddenly and unexpectedly at the beginning of the year. I finally got it together to sell the scooter, but was just contacted by the seller that the brown key is missing. I looked everywhere but my husband never told me about it and I just don't know where to find it. Then I searched the forum and learned about JimH.
Any solid recommendations on where I can clone the key and how concerned should I be about not having the master key?
