Now you should have the necessary tools for picking an American Lock Series A1100.

Step 1: Preparation

Before you begin picking the lock, ensure you are in a well-lit area with minimal distractions. It’s helpful to have a clear view of the lock’s keyway. Familiarize yourself with the lock by examining its components and understanding how the pins interact with the key.

Step 2: Insert the Tension Wrench

Insert the tension wrench into the bottom of the keyway, applying slight tension in the direction you would turn the key to unlock the lock. Keep the tension consistent throughout the picking process.

Step 3: Insert the Lock Pick

Insert the lock pick above the tension wrench, aligning it with the pins inside the keyway. Gently push the lock pick upward, feeling for any feedback or resistance from the pins.

Step 4: Apply Tension and Manipulate the Pins

While maintaining tension with the wrench, individually lift each pin using the lock pick. Start from the back of the keyway and work your way forward. As you lift each pin, pay attention to any binding or resistance, as this indicates that the pin is set correctly.

Step 5: Repeat the Process

Continue manipulating the pins, setting them one by one until all pins are in the correct position. The lock will gradually turn as each pin sets. Once all pins are set, the lock will rotate fully, and you will have successfully picked the American Lock Series A1100.

  2. Rushing the Process: Lock picking is a skill that requires precision and attention to detail. Rushing the process can lead to mistakes and frustration. Take your time and focus on each pin individually.
  3. Neglecting Maintenance: Over time, locks can accumulate dust and debris, affecting their performance. Regularly clean and lubricate your lock picks and tension wrench to ensure optimal performance.
