Please adhere to the steps in the specified order.

👉️ Watch Video Tutorial Below.

Position the Strike Plate

Begin by correctly positioning the strike plate on the door jamb. Secure it by tightening the screws.

  • Tip: Sometimes, the strike plate of a new door lock may not fit perfectly into the existing placement. In such cases, you can reuse the strike plate from your previous lock, as most knob locks are designed to be universal and do not require a new strike plate.

Assess Door Holes

If you're replacing an existing lock, the necessary holes should already be present in the door. However, if your door doesn’t have the required holes, consider enlisting the help of a carpenter to drill the appropriate holes.

Install the Latch Assembly

Insert the latch assembly of the lockset into the door. Secure it by tightening the screws on the faceplate. At this point, your latch should be successfully installed.

Remove the Interior Knob

To proceed, you will need to remove the interior knob. Locate the small hole next to the inner knob (get help from our tutorial video). Using a spanner wrench, push the retainer pin to release the knob, then pull it off. Next, unscrew the rosette by turning it counterclockwise.

Insert the Lock Assembly

Now, insert the lock assembly into the hole in the door. It's crucial to ensure that the retainer legs correctly hook onto the latch assembly. For clarity, I will demonstrate using the latch from an old lock to show how the parts engage.
