High security locks are built with high-quality materials and engineered precisely according to the manufacturer’s guidelines. High-security locks make use of pin tumblers, a type of lock that features two or more coiled chambers in its cylinder composed of stacked pins which fit into the plate that is embedded within the door frame. High security locks typically require a key designed specifically for them, which means you cannot unlock them using a standard “housekey” or other kinds of keys. High-security locks also feature anti-pick shields over the keyway to prevent lock-picking. High-security locks will only be made by specific manufacturers because each has their own patent protections. High-security locks are commonly used in business, banks, Mansions and other kinds of high-risk facilities for security purposes.
