High Security Locks earn their namesake only after completing a series of tests outlined in BHMA and UL 437 listings. These locks are tested to withstand many forms of physical attack, including picking, drilling and bumping.
Other benefits to high security locks are their restricted keys which boast 3 core principles of security: They are patented to prohibit unauthorized duplication, are recorded for audit capability and have cross-platform capacity to allow for the largest master-key possibilities available.
Restricted locks are named so due to the key restriction (as above with High Security locks) and patented keyways. They do not undergo the same testing and do not have the same physical security as full High Security, but are still much safer than your typical box-store-lock.
While some locksmiths infer that restricted locks are “basically the same” as high security, they are not! There is a significant difference.
Non-Restricted Locks. Your most common locks on the market have been used for centuries. Representing about 70% of locked openings globally, these locks have no restrictions and can be manipulated by physical tools. Best used in situations to keep “the honest people out”, these type of general locks can have keys duplicated or created at any corner store.
Although “Do Not Copy” can be stamped on keys for these locks, this has absolutely no impact on a the ability to cut the key.
Keyless entry locks are can be either strictly mechanical or electronic. Mechanical versions are usually referred to as “pushbutton locks” and have longer lifespans than electronics. They are susceptible to needing maintenance, however, as moving parts do need to be lubricated and maintained for proper functioning. Electronic versions can be accessed by either a code or a fob/card.
While generally having a lesser lifespan than mechanical, electronic keyless entry locks are most commonly used in residential settings where usage is less than commercial. A quality electronic keyless entry will have a key over-ride which can come in very handy if you find yourself in a sticky situation such as a dead battery.
