The passage door knob is a popular feature of homes and offices. It allows you to easily open and close the doors without needing a locking device. You may need to adjust your lock, especially if you are installing a new door knob or making changes to the existing one. It is important to know how to extend a lock on a passage door handle to ensure functionality and proper installation.

Why would you need to extend the lock on a passage door knob?
Two main reasons are often needed to extend the lock on a passage doorknob:
- Backset adjustment: The distance between the edge of the opening and the center of where the handle or knob is to be installed is called the backset. Backset measurements are usually 2-3/8 or 2-3/4 inches. You’ll have to extend or adjust the latch if your existing door backset does not match your knob.
- Retrofitting Doors from Older Homes: Many older houses have doors that are not standard. Installing a new passageknob on an old door may require extending the latch in order to accommodate a difference in backset.
- For improved functionality, it is important that the lock and strike plate are aligned correctly. Adjustments are a great way to avoid misalignment which can lead to operational issues.
What Tools and Materials Do I Need?
Gather the following tools before you begin the process to ensure that it is efficient.
- Screwdrivers (flathead or Philips depending on the screw)
- Tape measure
- If your latch is not adjustable, you will need to replace it.
- Drill (optional for new installations or door adjustments)
- Marking pencil (for marking measurements).
Step-by-Step Guide: How to Extend the Lock in a Passage Door Knob
Step 1: Measure your Backset
To begin, measure the backset of your door. Measure the distance between the door edge and the existing knob hole using a tape. This is usually 2-3/8 or 2-3/4 inch. This measurement is crucial for the correct alignment and operation.
Step 2: Remove existing Latch
- Use a screwdriver to remove the faceplate, the metal plate at the edge of the front door.
- Pull the latch mechanism gently out of the door. Note its orientation – the angled side should face in the direction that the door closes.
- Check the latch to see if it is adjustable. The sliding or pin mechanisms of adjustable latches allow for easy extension.
Step 3: Adjusting the latch (if Adjustable).
Your latch may be adjustable.
- Find the pin or sliding mechanism on the latch.
- The latch can be extended by sliding or pulling the mechanism.
- Make sure the adjustment is tight and the latch remains extended.
If your latch cannot be adjusted, you will need to buy a replacement latch that is compatible with the knob and door dimensions.
Step 4: Install the Latch
The latch can be adjusted by:
- Insert the latch into the door. Make sure the angled edge of the bolt is facing the right direction (towards the frame).
- Fix the faceplate to the door edge by aligning it.
Step 5: Replace the doorknob
- Insert the spindle of the passage knob through the latch mechanism.
- Attach the levers or knobs to either side of the doors, aligning them with the latch.
- To secure the knob, tighten the screws.
Step 6: Check the lock and latch
- Close and open the door to see if the latch retracts and extends smoothly.
- If there are issues, you may need to adjust the strike plate position or make minor modifications to the door frame. You may need to make small modifications to the frame or adjust the strikeplate position if there are problems.

Common Challenges, and how to overcome them
- Non-Adjustable Latch If the latch on your door is not adjustable, then you will need to buy a latch that can accommodate both backsets. The majority of hardware stores sell universal latches that are designed to meet this need.
- Misalignment of the Strike Plate If the latch is not aligned with the strikeplate, remove it and reposition. Mark the location with a pencil and drill new pilots holes if needed.
- Older or damaged doors Older doors can have structural problems or irregular measurements. Consider hiring a professional in such cases to ensure that the door is fitted precisely and securely.
Installing a smooth installation
- Select the Right Latch – Make sure your latch matches your door and passage knob measurements.
- Handle with care: Do not overtighten screws as they can damage the latch or knob.
- Invest in Quality Tools. Choosing the right tools will make the process easier and faster.
- Refer to the manufacturer’s instructions: For specific installation instructions, always refer to your manufacturer’s instructions that came with your knob or latch.
Why Proper Installation is Important Extending the locking mechanism in a passage knob is not just for aesthetics and convenience, but it’s also essential to the functionality and durability of the door. Locks that are properly installed:
- Improve Security: Even doors that don’t lock need to be closed securely to maintain privacy.
- Prevent wear and tear: A misaligned latch can cause damage to your door hardware over time.
- Assuring Smooth Operation: By ensuring that the latch is correctly adjusted, you can ensure that the knob will operate without any resistance or sticking.
