The SLS-1 key lock set is designed to replace the standard wing-nut locking mechanism on any of the "DV" mounts and accessories.  If you live in a high crime area or are concerned with someone taking your antenna, replace the wing-nut locking hardware with the SLS-1 and keep the locking key with the vehicle keys.  All of the locking hardware in the SLS-1 is finished with matching black chrome.
