What Defines a “High-Security” Lock?
To be classified as high-security, a lock must go beyond just being “heavy.” It typically requires three specific certifications:
- Restricted Key Control: You cannot take these keys to a local hardware store to get a copy. Duplication requires a specific security card and can only be done by authorized dealers.
- Manipulation Resistance: These cylinders are designed to be “bump-proof” and highly resistant to picking, often using complex pin systems (like Medeco‘s biaxial pins).
- Physical Durability: High-security locks feature hardened steel inserts and drill-resistant plates to stop attackers using power tools.

- ASSA ABLOY: Known for extreme durability and integration with electronic Access Control systems.
- Schlage (Primus/Everest): Offers excellent key control and is compatible with standard door prep, making it a favorite for Atlanta office retrofits.
- Mul-T-Lock: Famous for their “telescopic pin” technology which makes picking nearly impossible.

Pro Tip: The “Audit Trail” Lock
In 2026, many Atlanta businesses are moving to intelligent keys (like Medeco CLIQ). These look like mechanical high-security locks but the keys are electronic.
Every time a key is used, it logs the event in your Access Control database. If a technician loses their key, you don’t have to re-key the whole building—you simply “delete” that key from the software.
