Top box spare key.

"If you end up replacing the lock with a padlock, make it a combination lock or carry a spare.
If you lock your keys inside your topbox, you might be lucky and there may be a council depot nearby, manned by a biker and doesn’t mind lending you a hacksaw..."

Doh!!

I've used a local (proper) locksmith for top box keys in the past, with success. Givi .. and I suspect other ... blanks are fairly rare, but good locksmiths seem to keep a very wide range... and their cutting is very good too. (They'll probably have the facilities to reprogram HISS and other transponder-type keys, as well).
