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 Overview

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

Medeco MED-100200T-05-DLT – Frequently Asked Questions

1) What is the Medeco M3 Standard 6-Pin Mortise Cylinder designed for?
This mortise cylinder fits standard commercial door preparations with 1-1/8" to 1-3/4" door thickness. The straight cam operates mortise locksets and panic hardware. DL keyway provides restricted key control.
2) Which mortise locks are compatible with this cylinder?
Compatible with most commercial mortise locksets including Corbin Russwin, Sargent, Yale, and others using standard ANSI A156.13 specifications. Verify cam length and throw requirements with your lockset manufacturer.
3) How do I determine the correct cylinder length for my door?
Measure door thickness precisely. This cylinder adjusts from 1-1/8" to 1-3/4". For doors outside this range, order specific length cylinders. Account for any door reinforcement or plates that add thickness.
4) What security grade does the Medeco M3 provide?
Medeco M3 meets ANSI/BHMA Grade 1 security standards. Features patented key control, drill resistance, and pick protection. Suitable for high-security commercial applications requiring restricted keyways.
5) Can I rekey this cylinder to match existing Medeco keys?
Yes, if you have proper authorization for the DL keyway system. Rekeying requires Medeco-trained locksmiths and authorized key cutting equipment. Maintain key control documentation per Medeco requirements.
6) What finish options are available for this mortise cylinder?
Standard finishes include satin chrome, bright brass, and oil rubbed bronze. Verify finish compatibility with your mortise lockset. Custom finishes may be available through special order.

Remove old cylinder, adjust new cylinder length to door thickness, and insert with cam aligned to lockset position. Secure with set screw if required. Test operation before final installation. Follow lockset manufacturer instructions.
8) What is the difference between straight cam and other cam types?
Straight cams work with most standard mortise locks and panic hardware. Offset cams are for specific applications. Match cam type to your lockset requirements or consult manufacturer specifications.

Medeco cylinders need minimal maintenance. Use approved graphite lubricant only - never oil-based products. Clean key regularly and avoid forcing operation if resistance occurs. Schedule professional service for high-use installations.
