Restricted Keyway Systems

Prevent Unauthorized Duplication

At Peifer Security Solutions, we understand that key control is the foundation of physical security. That’s why we specialize in restricted keyway systems that prevent unauthorized duplication and enhance access control across your facility. Our flagship brand, Medeco, leads the industry in patented key technology, offering unmatched protection for institutions that demand the highest level of security.

Whether you’re securing a hospital, government building, school, or commercial property, our restricted keyway systems are designed to deliver reliable, scalable, and tamper-resistant solutions.

Why Medeco?

Medeco is the gold standard in restricted keyway technology. Known for its patented key control, Medeco locks are engineered to resist picking, drilling, bumping, and unauthorized duplication. Unlike standard keys that can be copied at any retail kiosk, Medeco keys require certified locksmiths and proper authorization for duplication, giving you full control over who has access to your facility.

Medeco’s commitment to innovation and security makes it the ideal choice for clients who need high-security locking systems with long-term reliability.

Patented Key Control

One of Medeco’s most powerful features is its patented key control system. Each key is protected by a unique design and patent, making unauthorized duplication virtually impossible. Only authorized personnel can request copies, and only certified locksmiths can produce them.

This level of control is essential for facilities where security breaches could have serious consequences, such as:

  • Healthcare institutions
  • Government agencies
  • Financial institutions
  • Educational campuses
  • Critical infrastructure

With Medeco, you can be confident that your keys, and your facility, are protected.

Master Key Systems

Medeco’s Master Key Department specializes in designing complex, secure master key systems that allow for tiered access control. These systems are ideal for organizations that need to manage multiple access levels across departments, buildings, or campuses.

At Peifer Security Solutions, we work closely with Medeco to create custom master key plans that balance convenience with security. Whether you need a simple two-level system or a multi-tiered hierarchy, we’ll help you design a solution that fits your operational needs.

Medeco Hybrid eCylinder: Smart Security Meets Mechanical Strength

Medeco Hybrid eCylinder: Smart Security Meets Mechanical Strength

For clients seeking the flexibility of electronic access control with the durability of mechanical locks, Medeco’s Hybrid eCylinder lines offers the perfect solution. These innovative locks combine traditional key-based security with electronic intelligence, allowing for audit trails, scheduling, and access control — all without the need for hardwiring or network infrastructure.

Key features of Medeco’s Hybrid eCylinder line include:

  • Electronic access control built into a mechanical cylinder
  • Audit trail capabilities to track who accessed what and when
  • Time-based access permissions for enhanced control
  • No wiring required, making installation fast and cost-effective
  • Compatible with existing hardware, ideal for retrofits

Much like CyberLock, Medeco’s eCylinders allow administrators to program keys, set access schedules, and revoke access remotely. This makes them ideal for facilities with dynamic staffing, contractor access or sensitive zones that require flexible control.

Whether you’re upgrading a legacy system or expanding your security footprint, Medeco’s Hybrid eCylinder line delivers smart, scalable protection with the trusted strength of Medeco hardware.

CyberLock: A Digital Twist on Secure Keys

In addition to Medeco’s mechanical solutions, Peifer Security Solutions also offers CyberLock, a powerful electronic key system that combines digital access control with physical security.

CyberLock keys are programmable, allowing you to set access schedules, expiration dates and audit trails. Each key stores access data, and each lock records entry attempts, giving you full visibility into who accessed what, when and where.

CyberLock is ideal for:

  • Facilities with rotating staff or contractors
  • Remote sites where traditional access control is impractical
  • Organizations that need real-time access management without wiring or network infrastructure

CyberLock keys are secure, flexible and easy to manage, making them a perfect complement to Medeco’s mechanical systems.
