Learning how to pick locks may sound intimidating at first, but it becomes manageable when broken into basic methods. One of the first skills new locksmiths learn is how to successfully manipulate locks by single-pin picking.
Single pin picking is used in residential and low-security commercial settings, making it effective for practice and real-world applications. The following guide breaks down the basics of single-pin picking locks and includes lock picking techniques for beginners.
Single-Pin Picking: What You Should Know
Single-pin picking involves isolating and manipulating each pin inside a lock individually until all of the driver pins are aligned with the shear line and the entire mechanism rotates. Unlike raking, which tries to move multiple pins at once, SPP is more precise and controlled.
Standard pin tumbler locks contain key pins and driver pins of varying heights that are stacked in columns and held in place by springs. When a key lifts all pins, so that the key pins and driver pins are aligned evenly with the shear line, the plug can turn.
A beginner’s first step is understanding how each component inside the lock responds to pressure. While applying light tension in the plug with the tension wrench and lifting each pin stack one-by-one, you will find the binding order in which to pick the lock. With tension applied, each pin will feel springy as it is lifted, except one: This pin will have some resistance because the driver pin above it is bound by the shear line. This binding pin is your starting point.
Once you set the binding pin to the correct height, the next pin in the sequence will begin to bind. This process continues until all pins are set and the lock opens. Practicing this method builds your dexterity and your understanding of how locks work internally.
Essential Tools for SPP
Every locksmith needs a reliable set of tools to work efficiently. For single-pin picking, start with basic lock picking kits that include a tension wrench and several pick styles, like hooks, offset picks and half-diamonds.
Tension wrenches come in various thicknesses to suit different keyways. Hooks and offset picks are available in a range of sizes and curve depths to navigate and effectively lift pin stacks of varying heights.
Invest in tools made from quality stainless steel, with a fine finish to ensure durability and effectiveness in the lock.
Some beginners also benefit from using practice locks with visible inner mechanisms, often called clear or cutaway locks. These allow you to see how your tools affect each pin, making it easier to learn the proper technique.
The Proper Technique for Picking
Begin by inserting the tension wrench into the bottom or top of the keyway and applying light tension in the direction the key would normally turn. Then, insert your pick and begin lifting the pins one by one, feeling for the binding pin.. Feel for one that resists slightly more than the others—this is usually the binding pin.
Lift the pin slowly. Feeling a small click and slight movement of the core indicates the driver pin is set. Continue this process pin by pin. Remember that the amount of tension is crucial—too much will bind the pins too tightly, and too little won't create the binding order you need.
If you find yourself stuck, reset the lock and start again. Consistency and repetition build the tactile feedback needed to become proficient.
Use feedback from each session to improve your touch and control. Over time, you’ll develop the sensitivity needed to detect subtle pin movements and recognize when you’ve fully set a pin.
