Introduction
This tutorial focuses on mastering the art of impressioning, a vital skill for locksmiths that allows them to create keys for locks without having the original key. Understanding impressioning can significantly increase efficiency, enabling locksmiths to complete jobs faster and tackle more complex tasks with ease. This guide will provide step-by-step instructions and techniques for impressioning both wafer and pin tumbler locks.
Step 1: Understanding the Basics of Impressioning
- Impressioning requires a clear visualization of the internal mechanics of a lock.
- Familiarize yourself with the types of locks:
- Wafer Tumbler Locks: Generally easier to impression.
- Pin Tumbler Locks: Considered more complex.
- Key principles:
- Binding the tumbler to prevent movement.
- Bumping the key to create marks.
- Releasing the tension to reevaluate the key.
Step 2: Gather Your Tools
- Essential tools include:
- Magnifying Visor: Enhances visibility of small marks.
- Locking Pliers: Use small vice grip pliers for a good feel of the lock.
- Impressioning Tools: Consider specialized tools like the Freeman or Jiffy models for better alignment.
- Files: Use fine-cut files like a pippin or pattern makers file for smooth cuts.
Step 3: Preparing the Key Blank
- File Preparation:
- Remove any plating from the key blank to create a smooth matte surface.
- Use draw filing to prepare the key before inserting it into the lock.
- Visual Inspection:
- Compare prepared versus unprepared key blanks. The prepared blank should have a uniform matte surface, making marks easier to see.
Step 4: Impressioning Wafer Tumbler Locks
- Insert and Bind:
- Insert the key blank and twist it to bind the tumbler.
- Bump the Key:
- Apply a gentle bump to the key to leave a mark. Repeat this process.
- Release and Inspect:
- Release the tension and inspect the key for marks. Rotate and adjust lighting to enhance visibility.
- File the Marks:
- Carefully file over the marks, ensuring to maintain smooth surfaces.
Step 5: Using the Figure 8 Method
- This method involves a simultaneous twisting and bumping action:
- Insert the key and perform a figure-eight motion while bumping.
- Always release tension between bumps to avoid misalignment.
Step 6: Impressioning Pin Tumbler Locks
- Understanding the Mechanism:
- Familiarize yourself with the shear line where the top and bottom pins meet.
- Repeat the Three Steps:
- Twist to bind, bump to make marks, and then release.
- Inspect for Marks:
- Look for round marks in the center of the key blade after each bump.
- File and Refine:
- File the key where marks are present, being careful not to over-file.
Step 7: Practice and Mastery
- The key to proficiency in impressioning is consistent practice.
- Take time to pause and reevaluate the marks left on the key.
- Develop an understanding of how different locks interact with the key.
