4. Step-by-Step Guide to Installing Locks

Step 1: Measure and Mark

Before measuring the lock, use a fresh install kit to decide the size you need. Most commercial locks are set farther from the edge, while residential locks are closer to the frame.
Measure the backset (the distance from the door edge to the hole’s center).
Mark where the lock and latch will go on the door.

Step 2: Drill Holes

For Wood Doors: Use a hole saw to drill the hole for the lock and latch.
For Metal Doors: Use a metal drill bit and drill slowly to prevent overheating.
Use a cup cutter to make the holes for the lock and latch. Watch this video for guidance.

Step 3: Install the Latch / Deadbolt

Insert the latch or a deadbolt into the edge of the door.
Secure it with screws, ensuring it sits flush with the door’s edge.

Step 4: Attach the Lock

Place the exterior and interior parts of the lock on either side of the door.
Connect them with screws and make sure they align.

Step 5: Add the Strike Plate

Mark the position for the strike plate on the door frame.
Secure the strike plate with screws. Use a chisel for wood frames to create a recess if needed.

Step 6: Test the Lock

Turn the key, knob, or handle to check if it locks and unlocks smoothly.

5. Tips for Installation

Use the correct drill bits for the door material.
Wear safety glasses during the process.
Ensure screws are tight but avoid overtightening.
Ask the customer for a broom or vacuum to clean up after yourself.
