Preparation and Safety Guidelines
Tools Needed
- Screwdriver (Phillips head and possibly a power drill)
- Leveler
- Quick Set Doorknob Assembly Set
Safety Guidelines
- Always turn off the power to the door circuit breaker before beginning any electrical work, if applicable (e.g., for electronic door locks). Failure to do so could result in serious injury or death.
- Use the correct type of screws for your door and doorknob. Using screws that are too long can damage the door or the door frame. Using screws that are too short will result in a loose and insecure doorknob.
- If you are unsure about any step of the installation process, consult a qualified professional. Improper installation can lead to security vulnerabilities or damage to your door.
Step-by-Step Instructions
Prepare the Door and Latch Mechanism
- If necessary, drill a hole for the latch mechanism (ensure you tape the other side of the door to prevent blowouts).
Prepare the Door and Latch Mechanism Install the Latch and Deadbolt
- Insert the latch mechanism, ensuring the 'up' marking is facing upwards. Insert the deadbolt, also ensuring the 'up' marking is facing upwards.
- Align the deadbolt rod with the latch, making sure it's properly aligned.
- Align the other half of the deadbolt with the half-moon shape on the latch. Before fully tightening, test the latch mechanism to ensure it works smoothly in both locked and unlocked positions.
- Hand-tighten the bolts, ensuring the 'lock' marking is at the top. Do not fully tighten yet; this allows for adjustment.
Install the Latch and Deadbolt Align and Secure the Deadbolt
- Use a leveler to ensure the deadbolt is perfectly horizontal and aligned before fully tightening the screws.
- Fully tighten the deadbolt screws.
Align and Secure the Deadbolt Install the Doorknob Handles
- Insert the doorknob handle through the latch, aligning it with the half-moon shape. Attach the other doorknob and test the latch again.
- Hand-tighten the screws for the doorknob, ensuring proper alignment. Use a leveler to ensure everything is level before tightening fully.
Install the Doorknob Handles Finalize and Test
- Test the doorknob's mechanism and adjust the half-moon-shaped rod to the left or right depending on whether your door is left or right-handed (this determines the latch position).
- Tighten all screws and test the functionality of the entire assembly. Ensure the door locks and unlocks correctly.

Tips
- Always check the orientation markings ('up' and 'lock') on the latch and deadbolt before tightening.
- Test the latch mechanism before fully tightening any screws. This ensures proper alignment and functionality.
- Use a leveler to ensure that the deadbolt and doorknob are installed horizontally and aligned correctly.
- Don't overtighten screws; hand-tighten initially to allow for adjustments before fully tightening.
- The half-moon mechanism on the doorknob can be adjusted for left-handed or right-handed doors. Determine your door’s swing direction to ensure the latch is positioned correctly.
Common Mistakes to Avoid
1. Incorrectly Measuring and Marking the Placement
Reason: Improper measurements lead to misaligned doorknob placement, resulting in difficulty operating the door or even damage.
Solution: Carefully measure and mark the door's thickness and the latch and strike plate positions before drilling any holes.
2. Striking Plate Misalignment
Reason: The strike plate is not properly aligned with the latch bolt, preventing the door from latching or causing it to bind.
Solution: Double-check the strike plate alignment with the latch bolt before tightening the screws.
3. Over-Tightening Screws
Reason: Excessive force can strip the screws, damage the door or doorknob, or crack the wood.
Solution: Tighten screws firmly but avoid excessive force; use a screwdriver that fits snugly to prevent stripping.
FAQs
What tools do I need to install a new doorknob?
You'll typically need a screwdriver (Phillips and flathead are common), a pencil, a measuring tape (optional), and possibly a level for precise alignment. Some doorknobs may require additional specialized tools, which will be specified in the manufacturer's instructions.
How do I choose the right doorknob for my door?
Consider your door's thickness when selecting a doorknob. Measure the thickness of your door to ensure compatibility with the doorknob's latchbolt. Also consider the style and finish to match your existing décor and security needs (e.g., keyed entry, privacy lock).
What if I can't get the old doorknob off?
Sometimes old doorknobs can be stubborn. Try using penetrating oil on any stuck screws to help loosen them. If you're still having trouble, gently tap on the screws with a hammer (protect the door's surface) to loosen them. If the issue persists, consulting a professional might be necessary.
