Hey there! I'm an OEM Door Lock Set supplier, and today I'm gonna walk you through the process of installing an OEM Door Lock Set on a wooden door. Whether you're a DIY enthusiast or just looking to save some bucks on installation, this guide is for you.

Step 1: Gather Your Tools and Materials

First things first, you'll need to gather all the tools and materials you'll need for the job. Here's a list of what you'll typically need:

  • OEM Door Lock Set: Obviously, you'll need the lock set itself. We offer a wide range of options, like the Golden Door Lever Handle, Mortise Door Handle Set, and Modern Door Locks. Make sure you've got the right one for your door.
  • Screwdriver Set: You'll need both flat - head and Phillips - head screwdrivers. Different parts of the lock set may use different types of screws.
  • Drill and Drill Bits: For making holes if required. Check the lock set instructions to see what size drill bits you need.
  • Measuring Tape: To measure and mark the correct positions on the door.
  • Chisel and Hammer: In case you need to create recesses for parts of the lock set.
  • Pencil: For marking the door.

Step 2: Measure and Mark the Door

Before you start drilling or cutting, you need to measure and mark the correct positions for the lock set on the wooden door. Here's how:

  • Read the Instructions: The lock set should come with detailed instructions. Read them carefully to understand where each part of the lock should go.
  • Mark the Borehole: Most door lock sets require a borehole in the edge of the door for the latch mechanism. Use your measuring tape to measure the correct height from the bottom of the door (usually around 36 inches, but it can vary). Mark the center of the borehole with a pencil.
  • Mark the Backset: The backset is the distance from the edge of the door to the center of the borehole. Common backset sizes are 2 3/8 inches and 2 3/4 inches. Mark this distance on the face of the door.
  • Mark the Strike Plate Location: On the door jamb, mark the location for the strike plate. Align it with the latch on the door when the door is closed.

Step 3: Drill the Borehole

Once you've marked the borehole, it's time to drill.

  • Select the Right Drill Bit: Use the drill bit size specified in the lock set instructions.
  • Drill Carefully: Place the drill bit at the marked center of the borehole. Start drilling slowly and keep the drill perpendicular to the edge of the door. Don't rush, as a crooked borehole can cause problems with the lock's operation.

Step 4: Create Recesses (if needed)

Some lock sets, especially mortise locks, require recesses in the door and door jamb.

  • Use a Chisel and Hammer: If your lock set needs a recess for the lock body or strike plate, use a chisel and hammer. First, score the outline of the recess with the chisel using light taps from the hammer. Then, carefully remove the wood within the scored area, working slowly and steadily. Make sure the recess is the right depth and size according to the lock set instructions.

Step 5: Install the Latch Mechanism

Now it's time to install the latch mechanism in the borehole on the edge of the door.

  • Insert the Latch: Slide the latch into the borehole. Make sure it fits snugly.
  • Secure the Latch: Use the screws provided with the lock set to secure the latch in place. Tighten the screws, but don't over - tighten, as this could damage the wood or the latch.

Step 6: Install the Interior and Exterior Handles

  • Align the Handles: Insert the spindle through the holes in the door and align the interior and exterior handles. The handles should fit together smoothly.
  • Secure the Handles: Use the provided screws to attach the handles to the door. Tighten the screws evenly so that the handles are firmly attached and operate smoothly.

Step 7: Install the Strike Plate

The strike plate goes on the door jamb.

  • Align the Strike Plate: Place the strike plate over the marked location on the door jamb. Make sure it aligns perfectly with the latch on the door when the door is closed.
  • Secure the Strike Plate: Use the screws to attach the strike plate to the door jamb. Make sure it's tightly secured.

Step 8: Test the Lock

After you've installed all the components, it's time to test the lock.

  • Open and Close the Door: Check if the door opens and closes smoothly. The latch should engage and disengage properly with the strike plate.
  • Lock and Unlock the Door: Use the key or the locking mechanism on the handle to lock and unlock the door. Make sure it works without any issues.

Step 9: Make Adjustments (if necessary)

If the lock doesn't work properly, you may need to make some adjustments.

  • Loose Handles: If the handles are loose, tighten the screws a bit more.
  • Misaligned Latch: If the latch doesn't align with the strike plate, you may need to adjust the position of the strike plate slightly. Use a chisel to make minor adjustments to the recess or move the strike plate and re - secure it.
