Have become aware of the search for a suitable case for a folding radio key on this part. This part is just great, both from the processing and the protection function for the accidental activation of the door opener or just the Aufklappknopfes for the key. This is to me so far gone hard on the laces, that the key just pops up in your pocket, because the button was pressed. That has now virtually completed and if the mistake does happen, the key still can not open due to the small size of the case.
