This is a convenient item that allows you to remove the key even when the GIVI top cases E43, B45, B42, B33, B32, C30, etc. are unlocked. It is compatible with the inner groove type key boxes shown in the third photo. The product is the black sleeve in the fourth photo; the box and key are not included. The box in the photo is an E43, but replacing it with this sleeve will greatly improve usability. It is recommended for those who open and close the case frequently or who find locking the case troublesome. Of course, you can still lock the case normally and remove the key. The material is brass, and it 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.
