This is a one-key system that allows you to open and close GIVI boxes with the Honda wave key for models such as the CT125 Hunter Cub, Monkey 125, 400X, NX400, NC750X, VFR800, CRF1100 Africa Twin, X-ADV, Rebel 1100, NT1100, and CB1300. Please be aware that sites other than Mercari and Yahoo! Auctions are likely scams. The product includes the items shown in the 8th photo: a sleeve, a gold-colored part, two screws, and a cylinder set. The box and key are not included. If your box is a Monokey type, you can purchase immediately. (For Monokey boxes that do not use a security key, confirmation is required, so please do not purchase immediately. Smart lock keys are not compatible.) For Monolock cases, you can convert to a one-key system by replacing the rotating claw with a Monokey type. If you want a rotating claw, it will be an additional 700 yen. There are two types of rotating claws: round and square, so please specify the same type as your case (see photo 5). S250 toolboxes and GRT720 can also be converted to a one-key system. As an added feature, the key can be removed even when unlocked (see photo 3), but to prevent the key from getting stuck, the bottom of the 6th tumbler has been slightly shaved down (see photo 7). There are tumblers from 1 to 6, and since it's only the bottom of the 6th tumbler, there should be little impact on security. For boxes where the keyhole does not turn 90 degrees sideways when unlocked (such as the TRK series and E43), the key may get caught when inserting or removing it while unlocked, for reasons other than the above. In that case, you can do it smoothly by slightly turning the key to the right while inserting or removing it. Photo 6 is a sample of key matching. The hole indicated by the red arrow is not used. The cylinder has been processed with screw cutting, making it a GIVI one-key system-specific cylinder. The material is brass, and it has been black-plated by a plating company. Converting to a one-key system improves usability, reduces the number of keys you need to carry, and makes things much more convenient. Here's a video on installation and key matching.
