  • Lesson 3 • History and Lock Taxonomy

    Traces lock evolution from warded to modern high-security designs. Establishes vocabulary used throughout the course.

  • Lesson 4 • Tolerances and Manufacturing Quality

    Explains how machining tolerances create security gaps. Students measure and classify lock quality using calipers and gauges.

Chapter 2See details

Lock Disassembly and Reassembly

  • Lesson 1 • Quality Control After Reassembly

    Teaches functional testing with plug followers, tension wrenches, and key gauges. Ensures locks meet manufacturer specifications before return to service.

  • Lesson 2 • Pin Tumbler Disassembly Techniques

    Covers follower, plug follower, and pinning tray methods for pin tumbler locks. Builds muscle memory for controlled spring retention.

  • Lesson 3 • Rekeying and Master Keying Basics

    Introduces pinning to a new key bitting and simple master key systems. Lays groundwork for advanced master keying in later chapters.

  • Lesson 4 • Disc and Wafer Lock Service

    Demonstrates disc detainer and wafer removal without damaging the shell. Prepares students for re-keying and repair tasks.

  • Lesson 5 • Lever Lock Disassembly

    Addresses bolt, lever pack, and curtain removal in lever mortice locks. Connects lever geometry to key bitting requirements.

Chapter 3See details

Key Cutting and Duplication

  • Lesson 1 • Code Cutting and Origination

    Explains bitting codes, depth charts, and space progression for cutting keys from code without an original. Enables service when originals are unavailable.

  • Lesson 2 • Key Impressioning

    Teaches the impressioning technique for originating keys from a lock without disassembly. Develops file control and mark-reading skills.

  • Lesson 3 • Manual Key Cutting Machines

    Trains students on clamp alignment, depth wheel calibration, and cutter maintenance for manual duplicators. Builds foundational cutting accuracy.

  • Lesson 4 • Automotive Key Cutting

    Addresses high-security automotive blades, laser-cut keys, and flip-key blanks. Connects blade geometry to transponder programming covered later.

  • Lesson 5 • Key Blank Identification

    Covers bow, shoulder, tip, and blade profiles across major blank families. Accurate blank selection prevents cutting errors and wasted stock.

Chapter 4See details

Master Key System Design

  • Lesson 1 • System Documentation and Security

    Establishes key control records, restricted key policies, and audit trail requirements. Protects system integrity over the facility lifecycle.

  • Lesson 2 • Bitting List Construction

    Covers total position progression, constant cuts, and MACS rules for building valid bitting lists. Prevents key interchange and phantom keys.

  • Lesson 3 • Master Key System Fundamentals

    Defines change key, master key, grand master, and great grand master levels. Establishes hierarchy logic before any system is designed.

  • Lesson 4 • Large-Facility System Design

    Applies hierarchy and bitting rules to multi-building campuses with hundreds of cylinders. Students complete a full design project with schedule and charts.

  • Lesson 5 • Pinning Chart Development

    Translates bitting lists into master pin, driver pin, and top pin specifications for each lock. Ensures correct shear line alignment at every key level.

Chapter 5See details

High-Security Cylinder Technology

  • Lesson 1 • Sidebar and Secondary Locking

    Covers sidebar, rotating element, and secondary shear line mechanisms that defeat standard picking. Builds understanding before bypass techniques are introduced.

  • Lesson 2 • High-Security Rating Standards

    Explains pick, drill, and manipulation resistance criteria used by independent testing bodies. Connects ratings to product selection for client applications.

  • Lesson 3 • Hardened Insert and Anti-Drill Features

    Examines carbide inserts, anti-drill pins, and hardened steel shells used to resist forced entry. Guides proper drill bit selection for legitimate service.

  • Lesson 4 • Cylinder Selection for Applications

    Guides matching cylinder security level to threat environment and budget. Students complete a written specification for a mixed-security facility.

  • Lesson 5 • Rekeying High-Security Cylinders

    Demonstrates manufacturer-specific re-keying kits, proprietary tools, and pinning sequences. Emphasises documentation required for restricted key systems.

Chapter 6See details

Safe Mechanics and Combination Locks
