Medeco® Rim & Mortise Cylinders – High Security UL437 Certified Cylinder Locks

Medeco® rim and mortise cylinders are designed to deliver unmatched key control and physical security for both commercial and institutional applications. Whether you're retrofitting existing hardware or upgrading your current security infrastructure, Medeco cylinder locks are the trusted choice for performance and protection.

Medeco Mortise Cylinder : 

The Medeco mortise cylinder is threaded on the outside shell and is designed to be easily installed into standard mortise lock cases from other leading manufacturers. A rear-mounted cam engages the locking mechanism, while a set screw secures the cylinder in place—ensuring reliable operation and compatibility with common lock hardware.

Medeco Rim Cylinder Overview

Rim cylinders are ideal for use with:

  • Surface-mounted deadbolts

  • Night latches

  • Panic devices

  • Jimmyproof locks (also known as vertical dropbolts or interlocking deadbolts)

They are secured with a backplate and two mounting screws, making them a versatile component for retrofitting or upgrading exterior door hardware.

High Security Features – Medeco M4 & M3 Cylinders

  • Medeco M4 cylinders offer utility-patented key control, UL437 certification, and resistance to physical attacks including drilling, picking, and bumping.

  • Medeco M3 cylinder options are also available, featuring sidebar technology and high-strength materials for superior attack resistance and master keying flexibility.

  • Special Angle-Cut Keys: Medeco’s proprietary angled cuts and restricted blanks make unauthorized duplication virtually impossible.

  • Sidebar Locking Mechanism: Prevents the key from turning until it is elevated, rotated, and properly aligned—offering enhanced protection against picking and bumping.

Key Control & System Compatibility

  • Patented key control ensures keys cannot be duplicated without authorization.

  • Retrofittable: Easily replaces standard mortise and rim cylinders in existing hardware.

  • Compatible with M4 BiLevel and larger Medeco master key systems.

  • Available in multiple formats, finishes, and keying configurations (keyed alike, different, or master keyed).

Applications

  • Commercial offices

  • Government buildings

  • Educational institutions

  • Healthcare facilities

  • Retail storefronts

  • Multi-unit residential properties.
