This is a convenient item that allows you to remove the key even when the top case is unlocked for GIVI's OUTBACK (OBK) series, ALASKA (ALA) series, DOLOMITI (DLM) series, TREKKER series such as TRK52, and V series such as V58, V56, and V47. This is for boxes that use the security key shown in the third photo. (Not compatible with smart lock keys) The product is the black sleeve in the fourth photo, and the box, key, and cylinder are not included. The box in the photo is OBKN58, but replacing it with this sleeve will greatly improve usability. It is recommended for those who open and close the box frequently or find it troublesome to lock the key. Of course, you can also lock it normally and remove the key. The material is brass, and it has been black plated by a plating company. Please refer to Daytona's official video for installation instructions. https://youtu.be/4jBcapDOshc If you have any other questions, please ask.
