High Security Locks: common questions
What makes a lock high security?
Pick and drill resistance built into the cylinder, hardened components, and a patented restricted keyway so blanks are not freely available. Products from manufacturers such as Medeco and Mul-T-Lock carry independent UL or BHMA ratings for these attacks.
What does Do Not Duplicate on a key actually mean?
Legally, very little. It is a request, and most hardware stores and kiosks will copy the key anyway. If you need to control who has keys, the answer is a restricted keyway where blanks are only available to authorized locksmiths and cuts are only made for people on your signed list.
Can restricted keys be copied?
Not through normal channels. The blanks are patent-protected and supplied only to authorized dealers, who cut them only for the signatories on your key control agreement. That control is the whole point of the system.
Can high-security cylinders be fitted to my existing doors?
In most cases, yes. High-security cylinders are made to retrofit standard commercial locksets, deadbolts, exit devices and padlocks, so you keep your existing hardware and upgrade only the cylinder.
