- Chisel: To create a mortise (recess) in the door for the lock.
- Hammer: To assist with chiseling and driving nails.
- Measuring Tape: To ensure accurate placement of the lock components.
- Safety Glasses: Essential for protection while drilling and chiseling.
Additional Materials
- Wood Filler: To fill any gaps or imperfections around the lock installation.
- Sandpaper: To smooth the filled areas.
- Paint or Stain: To match the color of the door after filling and sanding.
Measuring and Marking the Lock Position
Step 1: Determine the Height of the Lockset
Measure the distance from the floor to the center of the doorknob or handle on the opposite door, if there is one. This measurement will determine the height at which the lockset will be installed on the new door.
Step 2: Mark the Lock Position Horizontally
Mark the center of the door edge horizontally, either at the edge or at a distance from the edge according to the lockset instructions. If the door is not yet hung, measure and mark the midpoint of the door’s width.
Step 3: Mark the Lock Position Vertically
Measure the height of the lockset from the floor, as determined in Step 1, and mark this point on the door edge at the horizontal center mark. Draw a horizontal line across the door edge at this point.
Step 4: Transfer the Lockset Hole Pattern
Place the lockset template or measure the distance between the lockset holes onto the door edge. Mark the hole positions for the latch, deadbolt, and handle on the horizontal line.
Step 5: Drill the Lockset Holes
Drill pilot holes at the marked locations for the latch, deadbolt, and handle holes. Use a drill bit that matches the diameter of the screws or bolts that will secure the lockset.
Refer to the table below for suggested door lockset heights:
| Lockset Type | Distance from Floor to Center of Lock |
|---|---|
| Knob or lever | 36-42 inches |
| Deadbolt | 60 inches |
Drilling the Pilot Holes for the Lockset
Once you have chosen the location for your lockset, it’s time to drill the pilot holes. These holes will guide the screws that will hold the lockset in place. To drill the pilot holes, you will need a drill, a drill bit, and a level.
First, mark the location of the holes on the door. Use a level to make sure that the holes are level. Then, drill the holes using a drill bit that is the same size as the screws that you will be using to install the lockset.
The size of the drill bit you need will depend on the size of the screws you are using. Here is a table that shows the recommended drill bit sizes for different screw sizes:
| Screw Size | Drill Bit Size |
|---|---|
| #8 | 1/16 inch |
| #10 | 5/64 inch |
| #12 | 3/32 inch |
Once you have drilled the pilot holes, you are ready to install the lockset.
Installing the Latch Strike Plate
Installing the latch strike plate is a crucial step in securing your door properly. Follow these detailed instructions to ensure a sturdy and effective locking mechanism:
1. Mark the Location
Hold the strike plate against the door jamb, aligning it with the latch on the door. Mark the corresponding holes on the jamb with a pencil.
2. Chisel the Mortise
Use a sharp chisel to carve out a mortise for the strike plate to sit flush with the jamb. The mortise should be slightly wider than the strike plate and deep enough to accommodate its thickness.
3. Align and Secure the Strike Plate
Place the strike plate in the mortise and align it carefully. Use screws to secure the strike plate to the door jamb. Ensure that the screws are driven in tightly and the strike plate is firmly anchored.
4. Adjust the Strike Plate for a Perfect Fit
After securing the strike plate, it’s essential to adjust it for a perfect fit. Use a flat-head screwdriver to rotate the strike plate slightly clockwise or counterclockwise. This fine-tuning ensures smooth engagement and disengagement of the latch with minimal friction.
| Clockwise Rotation | Counterclockwise Rotation |
|---|---|
| Tightens the strike plate | Loosens the strike plate |
| Moves the door away from the jamb | Moves the door closer to the jamb |
Test the latch engagement several times to verify a proper fit. Adjust the strike plate as needed until the latch locks and unlocks smoothly without any binding or rattling.
Mounting the Lockset
1. **Mark the door:** Hold the lockset against the door and mark the outline using a pencil.
2. **Chisel the mortise:** Use a chisel to create a mortise in the door to accommodate the lock body. The mortise should be slightly wider than the lock body and deep enough to allow the faceplate to sit flush with the door’s surface.
3. **Install the latch:** Insert the latch bolt into the mortise and secure it with screws.
4. **Mount the lock body:** Place the lock body in the mortise and align it with the latch bolt. Secure the lock body with screws.
5. **Mount the faceplate:** Position the faceplate over the lock body and secure it with screws. For added security, you can reinforce the faceplate with strike reinforcement plates:
| Type | Description |
|---|---|
| Standard Strike Plate | A basic metal plate that is attached to the door jamb and provides a resting place for the latch bolt when the door is closed. |
| Deadbolt Strike Plate | A stronger plate that is typically used with deadbolts. It has a hole that the deadbolt must penetrate when the door is locked, providing additional protection against forced entry. |
| Strike Plate with Bolt Guide | Similar to a deadbolt strike plate, but with an added guide that helps align the deadbolt as it enters the plate, making it harder to defeat by bumping or jiggling. |
6. **Test the lock:** Open and close the door to ensure that the lock functions properly. The latch bolt should extend and retract smoothly, and the deadbolt (if applicable) should engage securely with the strike plate.
Installing the Lock Cylinder
The lock cylinder is the heart of any door lock, and it’s important to install it properly to ensure that the lock functions correctly and securely. Follow these steps to install the lock cylinder:
- Remove the old lock cylinder. If there is an existing lock cylinder, remove it by inserting the key and turning it to the unlock position. Then, use a screwdriver to remove the screws that hold the cylinder in place and pull the cylinder out of the door.
- Insert the new lock cylinder. Align the new lock cylinder with the hole in the door and insert it into the door. Make sure that the cylinder is fully seated in the hole.
- Secure the lock cylinder. Use the screws that came with the new lock cylinder to secure it in place. Tighten the screws until the cylinder is snug, but do not overtighten them.
- Install the strike plate. The strike plate is the metal plate that the door lock latch engages with when the door is closed. Place the strike plate on the door frame and mark the location of the screw holes with a pencil.
- Drill pilot holes. Drill pilot holes at the marked locations. The pilot holes should be slightly smaller than the screws that will be used to secure the strike plate.
- Install the strike plate screws. Insert the screws into the pilot holes and tighten them until the strike plate is securely attached to the door frame.

Securing the Lockset with Screws
7. Installing the Strike Plate
The strike plate is the metal piece that the latch or deadbolt engages with when the door is closed. It is essential to install the strike plate correctly to ensure that the lockset functions properly and securely.
To install the strike plate:
- Place the strike plate on the door jamb where the latch or deadbolt will engage with it.
- Mark the location of the screw holes.
- Drill pilot holes for the screws.
- Drive the screws into the strike plate to secure it to the door jamb.
| Screw Size | Recommended Pilot Hole Diameter |
|---|---|
| #8 x 1-1/2″ | 1/16″ |
| #9 x 1-3/4″ | 3/32″ |
Make sure the strike plate is aligned properly so that the latch or deadbolt engages with it smoothly. If the strike plate is not properly installed, it can cause the lockset to malfunction.
Testing the Lock’s Functionality
Once the lock is assembled, it is important to test it thoroughly to ensure that it functions correctly and meets your security requirements.
Basic Functionality
First, test the basic functionality of the lock by inserting the key and operating it several times. Check that the key turns smoothly and unlocks the door without any difficulty. The lock should also lock securely when the key is removed.
Durability
To assess the durability of the lock, perform multiple lock and unlock cycles. Repeatedly insert the key and operate the lock to simulate the wear and tear it might experience during regular use. Ensure that the lock remains functional after prolonged use.
Environmental Resistance
Depending on the intended use of the lock, consider testing its resistance to environmental factors. If the lock is intended for outdoor or harsh environments, expose it to moisture, extreme temperatures, or vibration to verify its resilience.
Key Copying Resistance
If key security is a concern, evaluate the lock’s resistance to unauthorized key copying. Attempt to create a duplicate key using a typical key maker or locksmith. If the lock cannot be unlocked by the copied key, it indicates increased key security.
Bumping Resistance
Test the lock’s resistance to bumping, a technique used by burglars to open locks by rapidly inserting and manipulating a key. Insert a key slightly into the lock and use a hammer or tool to strike the key, trying to force it into the unlocked position.
Picking Resistance
Assess the lock’s picking resistance by attempting to open it using various lock picking tools. Use a variety of probes, tension wrenches, and rakes to manipulate the lock’s internal mechanism and try to unlock it without the correct key.
Bolt Throw
Measure the bolt throw, the distance the lock’s bolt extends into the strike plate when locked. This is important for determining the lock’s level of security, as a greater bolt throw provides increased resistance to forced entry.
Backset
Determine the backset, the distance from the edge of the door to the center of the lock’s keyhole. This measurement affects the security and convenience of the lock, as a larger backset makes it more difficult to manipulate the lock from the outside.
Security Grade
Research and compare the security grade of the lock you are testing. Security grades are assigned by independent organizations and indicate the lock’s level of protection against various types of attacks. Higher security grades typically denote higher levels of resistance to forced entry and unauthorized access.
Reinforcing the Door Frame for Security
The door frame is the weakest link in most doors, so it’s important to reinforce it to improve security. Here are some ways to do it:
Install Door Jamb Reinforcement Plates
These metal plates are installed on the inside of the door jamb and help to prevent the door from being kicked in. They are available in a variety of sizes and styles to fit most doors.
Add Deadbolt Strike Plates
A deadbolt is a more secure lock than a regular doorknob, but it’s only as strong as its strike plate. Strike plates should be made of metal and at least 2 inches long. They should be installed into the door frame using wood screws.
Upgrade to Heavy-Duty Hinges
Standard hinges can be easily damaged, so it’s a good idea to upgrade to heavy-duty hinges. These hinges are made of thicker metal and have more screws, making them more difficult to break.
Install a Door Alarm
A door alarm will sound an alarm if the door is opened without your permission. This can help to deter burglars and alert you to a break-in.
Use Door Armor
Door armor is a type of security film that can be applied to the inside of your door. It helps to hold the door together if it is broken, making it more difficult for burglars to gain entry.
Install a Peephole
A peephole allows you to see who is at the door without opening it. This can help you to avoid opening the door to strangers or unwanted visitors.
Use a Door Barricade
A door barricade is a device that can be used to prevent the door from being opened from the outside. This can be a good option for added security when you are at home or away.
Secure Sliding Glass Doors
Sliding glass doors are often a target for burglars, so it’s important to take steps to secure them. Here are some tips:
| Security Measure | Description |
|---|---|
| Install a Sliding Door Lock | This type of lock prevents the door from being opened from the outside. |
| Add Security Bars | Metal bars can be installed on the inside of the door to prevent it from being forced open. |
| Use Door Alarms | Door alarms can be used to sound an alarm if the door is opened without your permission. |
| Secure the Track | The track at the bottom of the door can be reinforced with screws or bolts to prevent it from being dislodged. |
| Install Security Film | Security film can help to hold the door together if it is broken, making it more difficult for burglars to gain entry. |
