Medeco® 4 Maxum® Residential Deadbolt – High-Security UL 437 Certified

The Medeco 4 Maxum deadbolt sets the benchmark for residential security, combining physical durability with advanced key control technology. Engineered with hardened steel inserts and rotating pins, this Medeco deadbolt resists picking and drilling in compliance with UL 437 standards.

Whether you're securing a home, apartment, or rental property, the Medeco Maxum deadbolt is the ultimate solution for protecting against bumping, wrenching, kicking, and other physical attacks. Its solid 1" hardened steel bolt is housed in heavy-gauge steel, making it one of the most robust deadbolts in the industry.


Unmatched Key Control & Anti-Tampering Technology

  • Medeco 4 utility patent protects against unauthorized key duplication.

  • Sidebar technology ensures the key must be elevated, rotated, and aligned before the lock will operate—offering protection from both picking and bumping.

  • Protection from 3D printing via a unique movable element in the key design.

  • Special angle-cut keys available only to authorized Medeco providers.


Security Features

  • Solid brass construction and strategically placed drill pins provide maximum drill resistance.

  • Heavy-duty steel shroud protects against “ice pick” attacks.

  • Reinforced strike plate with 2” anchor screws resists forced entry via kick-ins.

  • Engineered to withstand crowbar attacks, wrenching, and brute-force impacts.
