Lesson 8: Installing Deadbolts - Part 3

Installing a deadbolt

Installing a deadbolt requires many steps. You need to prep yourself and the door for the installation process. Before you drill, your holes need to be perfectly marked, and after you drill, things like chizzeling and assembling the lock add those finishing touches.

To begin your prep, assemble your installation kit. Check to make sure your drill batteries are charged or that you have an extension cord available. Ensure that you have all the drill bits and supplies necessary.

Mark the door using the instillation kit door jig. Wrap the jig around the desired part of the door, approximately 4” above the handleset. Insert the hole saw into the large hole in the jig on the front and back of the door. Apply some pressure and rotate the hole saw so that it marks the door. Do this for each side. Now insert a spade bit into the small hole on the jig. Apply some pressure and rotate the spade bit. This will mark the hole you will drill for the bolt.

Remove the door jig and put on your safety equipment.Use the hole saw bit to drill the deadbolt hole. Align the hole saw to the mark on the front door. Turn on the drill and apply steady light pressure in a forward direction. Drill as straight as you can until you are about 3/5th of the way through the door, then remove the hole saw and repeat the process on the other side. When you are done, there should be a smooth round hole in the door, and a cylinder of wood in your hands.

Use the spade bit to drill the hole for the bolt. Align the spade bit to the mark you made with the jig on the edge of the door. Turn on the drill and apply steady light pressure in a forward direction. Drill as straight as you can until the spade penetrates through to the deadbolt hole.

Now prepare the frame of the door by marking it for a bolt hole. To do this, insert the bolt hole marker into the bolt hole of the door. Close the door and use a flat head screwdriver and a hammer to tap on the bolt hole marker so that it hits the frame of the door. Remove the bolt hole marker and open the door.Use the spade bit to drill the hole for the bolt. Align the spade bit to the mark you made with the bolt hole marker. Turn on the drill and apply steady light pressure in a forward direction. Drill as straight as you can until the spade has penetrated 2” into the frame of the door.

After the holes have been drilled its time for the finishing steps. You will need to mark the edge of the door and the frame so that you can chizzel a gap for the strike plate and face plate to sit flush. After that the lock needs to be assembled onto the door.

Before you can begin chizzeling you need to mark your edges. A good chizzel job can make the difference between high-quality work and an unsatisfied customer. To mark the edges you will need the marker set and a hammer. Insert the nub of the marker into the bolt hole. Check to make sure the lines are parallel to the door then tap on the back ed of the edge marker. This will indent lines that will guide you as you chizzel. Everything inside the lines needs to be chizzeled away. Start by making a few cuts into the middle of the area you need to chizzel. Try to remove chips in small and smooth strips.

Now you can assemble the deadbolt. Start by putting the bolt into the bolt hole and installing the bolt screws. Now you can install the front of the deadbolt. Thread the tailpiece and retainer screws through the bolt, into the thumbturn and housing. Make sure you always install the deadbolt with the bolt drawn out otherwise you will have timing issues that will make the deadbolt work incorrectly. Now screw on the thumbturn and strike plate to finish the job.
