Medeco® Maxum® Deadbolt – Grade 1 High-Security Locking Solution

The Medeco Maxum® deadbolt is engineered for maximum resistance against physical and covert attacks.

Built with solid brass construction and enhanced by hardened steel components, the Maxum® deadbolt delivers powerful protection against drilling, picking, bumping, and prying. It’s offered in single-cylinder, double-cylinder, or captive thumbturn configurations for tailored security and egress needs.

Medeco M3 & M4 Technology – Elite Key Control & Attack Resistance

Whether integrated with Medeco M4 or legacy Medeco M3 key systems, this deadbolt offers industry-leading control and protection:

• Medeco M3 Deadbolt configurations utilize sidebars and hardened inserts to resist covert attacks.

• Medeco M4 cylinders add patented movable key elements and enhanced anti-3D printing features.

• Sidebar mechanism prevents the key from rotating until all elements are perfectly aligned, defeating bumping and picking techniques.

If you're already using a Medeco M3 cam lock or cylinder system, the Maxum can be master-keyed into your existing M3 or M4 key systems—ensuring compatibility, security, and convenience across platforms.
