Same on my GF's NT700 these days, apparently she tried to rotate the barrel with the key only partly in...
Managed to straighten it, but a significant crack opposite to the deep profile cut, definite risk of braking soon...
Since it's the OEM case, hence made by Givi, I went for a
Givi Z140R spare lock set size 40
Swapping went like a breeze, under a minute or so... lift the latch, pry the cir-clip off, pull the bar off and the barrel out, insert new kit in reverse order, circlip on, check with pliers that it's properly seated, check proper operation, done...
Contrary to the product picture has Givi changed the design/concept of how they cut those keys:
Improved safety against picking and the remaining shank is way more rigid and resistivity against unintentional abuse...
