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. The product includes the items shown in photo 8: 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 it 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 them to one-key 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 (photo 5). S250 toolboxes and GRT720 can also be converted to one-key. As an added feature, the key can be removed even when unlocked (photo 3), but to prevent the key from getting stuck, the bottom of the No. 6 tumbler has been slightly shaved down (photo 7). There are tumblers from No. 1 to No. 6, and since it's only the bottom of No. 6, there should be little impact on security. For boxes where the keyhole does not turn 90 degrees horizontally when unlocked (TRK series, E43, etc.), the key may get stuck when inserting or removing it in the unlocked state, separate from the above reason. 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 conversion-specific cylinder. The material is brass, and it has been black-plated by a plating company. One-key conversion improves usability, reduces the number of keys to carry, and makes it very smart. Here's a video on installation and key matching. Please take a look. https://youtu.be/Ykf__OO0Ssk If you have any questions, please ask. Price negotiation is not possible. Immediate purchase is OK. Thank you.
