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. This item is for 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 there is a deepest valley and that deepest valley is to the right of the highest peak, problems will occur. The key in the photo is on the left side, so there will be no problems. Depending on the key pattern, there may be keys that do not have the deepest valley or the highest peak. There is also a way to deal with keys that cannot be removed. Just identify the location of the deep valley and remove the tumbler plate. To remove it, simply push it from the back with a flathead screwdriver or similar tool. ☆☆☆ Replacing this sleeve will greatly improve usability. It is recommended for those who open and close the box frequently or who find locking the key troublesome. Of course, you can also lock it normally and remove the key. The material is brass, and the sleeve has been treated with black plating 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.
