FWIW - when I owned a Piaggio their forum described the method for opening the seat without the key. Then folks started having their scooters broken into by thieves who read the method.

Their solution was to stop posting and send a PM only to registered members with a specific minimum number of posts. The thefts were reduced, particularly after the moderators removed old posts describing the method.

Something to consider here? We may think it's obvious how to access the trunk, but how often the question gets asked tells me it's not so obvious. So why advertise it?
