Medeco 320201T M3 32 Series 6-Pin Large Format Interchangeable Core (LFIC) with DL Keyway and Drill & Pick Resistance

Medeco M3 32 Series 6-Pin Large Format Interchangeable Core (LFIC) with DL Keyway

The Medeco M3 32 Series Large Format Interchangeable Core (LFIC) is a heavy-duty, Grade 1 commercial cylinder engineered for rapid, tool-free rekeying by non-technical personnel using a special control key. Constructed of durable machined brass components, this 6-pin LFIC features the control/locking lug positioned at the middle of the core, providing additional protection against dent puller attacks. Compatible with Medeco rim and mortise cylinder housings, padlock bodies, Maxum deadbolts, Embassy knob and lever cylindrical locksets, and Simplex Unican, the 32 Series delivers versatile deployment across a wide range of commercial door hardware applications. UL437 listed for drill and pick resistance, this core meets universal standards for forced-attack protection.

Key Features

• Rapid Core Exchange: Cores can be quickly and easily changed by non-technical personnel using a special control key, effectively "rekeying" the lock without disassembly — eliminating the need for outside service personnel for routine rekeying.
• Middle-Position Control/Locking Lug: The 32 Series positions the control/locking lug at the middle of the core, providing additional protection against dent puller attacks compared to rear-lug designs.
• Coordinated Key Cuts: Coordinated cuts between operating keys and control keys eliminate the need for build-up or control pins, simplifying pinning and master key system integration.
• UL437 Listed: Certified to meet universal standards for drill and pick resistance, standing up to forced-attack methods for reliable high-security performance.
• Machined Brass Construction: Cylinders are constructed of durable machined brass components, designed to last the life of your equipment in demanding commercial environments.
• Patented M3 Key Control: Patented Medeco M3 keys may only be duplicated by Medeco or an authorized Medeco service outlet, and only upon your request — providing strict key control and unauthorized copy prevention.
• Flexible Keying Options: Locks can be keyed alike, keyed different, or master keyed to accommodate a wide range of security and access management requirements.
• Broad Hardware Compatibility: Fits Medeco rim and mortise cylinder housings, padlock bodies, Maxum deadbolts, Embassy knob and lever cylindrical locksets, and Simplex Unican for versatile installation options.
