Introduction: How to Make Your Own Security Pins

I show how to make security pins for pin-tumbler locks using common tools and materials. The pins are made by securing them in a drill or rotary toot and using needle files to shape the pin in a common or hybrid design. A security pin is a modified version of a key or driver pin in a pin-tumbler lock that makes manipulation more difficult. Security pins are commonly designed to prevent lockpicking, but are also designed to resist decoding, impressioning, key bumping, and other compromise techniques. Similar modifications to components in non-pin locks are also common, with serrated components being the most popular in both wafer and lever locks. Combination and disc-detainer locks commonly use false gates to prevent manipulation. You can add security pins to your locks that don’t have them to make them more secure.

Step 1: Materials

- Needle Nose Pliers or Tweezers

- Needle Metal Files

- Small Clamp

- Drill or Rotary Tool

- Small Drill Chuck

- Key Pins and Driver Pins from a Lock

Step 2: How Security Pins Work

Security pins are designed so that use of a tool other than a key will trigger the pins and lock one or more pins at the shear line. This can be due to individual manipulation of components or tension on the cylinder. When triggered, security pins bind between the plug and cylinder, blocking the rotation of the plug until tension on the cylinder is released and pins are dropped back to their resting position.

    You get a bunch of spare pins when you buy a lock rekeying kit at a hardware store. The kits are designed to rekey locks to match 1 key, for example so your front door, back door, and deadbolts would all use the same key. That's where I've seen the color coded pins shown in the photos, each color is a different length.

    Very nice! I only wish you had offered more guidance about when to use each type. Still, it is easy to follow and informative. Thanks!

    Interesting. I never thought about making my own lock parts before.
