The security of any locking system is dependent upon two very important factors. First, protecting against attacks such as picking, drilling, bumping, and forcing. Second is to control duplication of existing keys. Anyone with even temporary access to original keys has no problem getting duplicates made for their own use if the keys and key blanks are not patent protected. The only way to ensure that keys cannot be copied without the consent of the owner is a key system with patent protected keys.
