This is a convenient item that allows you to remove the key even when unlocked for GIVI top cases such as B47, B37, B27, E470, E450, E370, E350, and E340. It is compatible with boxes with the outer groove type shown in the third photo and silver handles on the keys. As shown in the seventh photo, if the key's central cut is facing upwards, it can be used even with keys that have red or black handles. The product is the black sleeve shown in the fourth photo; the box and key are not included. ☆☆☆ Please consider the following points, as there may be issues where the key cannot be removed when unlocked depending on the key shape. ★★★ As shown in the fifth photo, if the deepest valley is to the right of the highest peak, problems may occur. The key in the photo is on the left side, so there will be no issues. Depending on the key pattern, some keys may not have the deepest valley or the highest peak. There is a solution if the key cannot be removed. Simply identify the location of the deep valley and remove the tumbler plate. To remove it, just push it from the back with a flathead screwdriver or similar tool. ☆☆☆ Replacing with this sleeve will greatly improve usability. It is recommended for those who frequently open and close the box or find it troublesome to lock the key. Of course, you can still lock the key normally and remove it. The material is brass, and the sleeve has been black-plated by a plating company. Please refer to the official Daytona video for installation instructions. https://youtu.be/MJDuljf_QHk Please ask if you have any other questions. No price negotiations. Instant purchase is OK.
