The point of a high-security cylinder is control over who can duplicate the key. Blanks are restricted and copies need the registered owner's sign-off, which matters on a shared street door that a dozen people and three contractors have had keys to. They also resist picking, bumping and drilling far better than standard cylinders.

Common questions
What makes a lock high-security?
A restricted key that cannot be copied without authorization, plus real resistance to picking, bumping and drilling.
Can I get extra copies later?
Yes, from us, with sign-off from the registered owner. That control is the whole point.
