When you buy a door lock, most retailers will ask whether your door opens to the left or the right. Many people are confused by this question and don’t know what “left†or “right†actually means. But it’s not that important to know which direction your door opens—what really matters is choosing a lock that can be easily adjusted or swapped. Fortunately, many modern locks are designed with interchangeable parts, making the process much simpler than it used to be. In this quick guide, I’ll show you how to adjust your door lock for left or right opening, as well as how to switch the internal and external functions of the latch. It’s a straightforward process that takes just a few minutes.
Step 1: Adjusting the Door Lock for Left or Right Opening
The first step is to position the door lock on the floor so that it's easy to handle. Make sure the door is open and the lock is in the correct orientation. Next, use a Torx screwdriver to remove the screws from the keyhole area. Once the screws are out, turn the handle in the opposite direction and reinsert the screws. This will effectively change the lock’s opening direction from left to right or vice versa.
Step 2: Adjusting the Latch (Tongue) for Internal or External Use
To adjust the latch, place the lock body on a flat surface. Press the locking tongue into the groove with your finger and then rotate it. Turn the tongue 180 degrees so that it pops out automatically. This action changes the function of the latch, allowing it to work properly on either side of the door.
By following these simple steps, you can easily customize your door lock to fit your needs without the need for professional help. Whether you're replacing an old lock or installing a new one, knowing how to make these adjustments can save you time and money. So next time you’re buying a lock, don’t worry about left or right—just focus on getting a lock that’s flexible and easy to adjust.
