This is a convenient item that allows you to remove the key even when unlocked for GIVI Monolock top cases such as the B47, B37, and B27. It is compatible with boxes that have the outer groove type in the third photo and keys with a red handle or a black handle. (Keys with key teeth on only one side are not supported.) It seems that there has been a recent specification change by GIVI, making it no longer possible to determine compatibility solely by the handle color. Please refer to the fourth photo and check the direction of the cut in the middle of your key. If the end of the cut is on the bottom, it's OK. If the end of the cut is on the top, you can use the [For Monolock Silver] item, which is listed separately. Please consider that option. For boxes like the E470, E450, E370, E350, E340, E260, and V35, where the key does not turn 90 degrees sideways when unlocked, removing and inserting the key when unlocked may be difficult. This depends on the key tooth pattern, so some keys may not get caught. If the key gets caught, you can try turning the key slightly to the right while removing and inserting it, or you can remove the first tumbler as shown in the fifth photo. To remove the tumbler, push it out from the back with a flathead screwdriver or similar tool. The product is the black sleeve shown in the fifth photo; the box, key, and cylinder are not included. Replacing the sleeve with this one 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 still lock the key in the usual way and remove it. The material is brass, and it has been black-plated by a plating company.
