How To Open A Doorknob Lock

Doorknob locks are the most common type of locks that you will find in residential homes. They are easy to use and convenient. However, there may be times when you find yourself locked out of your own house because you forgot your keys or you accidentally locked yourself out. In this article, we will guide you on how to open a doorknob lock.

What You Will Need

Before we start, you will need a few things to open a doorknob lock. These include a tension wrench, a pick, and a screwdriver. You can buy these tools at your local hardware store or online.

Step 1: Insert the Tension Wrench

The first step in opening a doorknob lock is to insert the tension wrench. This tool is used to create tension on the lock, which will allow you to turn the lock. Insert the tension wrench into the bottom of the keyhole.

Step 2: Insert the Pick

Next, insert the pick into the top of the keyhole. Use the pick to feel the pins inside the lock. Push the pins up one by one until you hear a click. This means that the pin is set.

Once all the pins are set, turn the lock with the tension wrench. The lock should open easily. If it doesn’t, repeat the process.
