Piaggio owners probably already know this.*
Just noticed that I'd stand a good chance of locking the key to my Liberty150i in the top case - unless I keep the ignition key separate from the case key!
Dismount at my destination - toss gloves and scarf in my top case - set keys in there - bump the lid closed. Have a nice cup of Joe.
......and I'm walking 27 miles home.
So, just bought a nice matching redheaded key to leave in the box lock.
(I'm never out of sight of my scooter - and usually sitting within 5 yards of it having coffee.... taking photos)
O.S.
*my lighted Bestem 929 case requires key in hand to lock
