High-security locks resist picking, bumping, and drilling and use restricted keys that cannot be copied at an ordinary hardware kiosk.
These locks combine hardened anti-drill pins, tight pick-resistant tolerances, and reinforced housings. Many carry a UL 437 rating, an independent standard for resistance to drilling and forced entry.
High-security systems use patent-protected key blanks that only authorized dealers can duplicate, so nobody can quietly run off extra copies of your key. That key control is often as valuable as the physical strength.
