Before you begin, it’s important to choose the right security lock for your door type and level of protection.

Tools and Materials Needed to Install Security Locks
Having everything ready beforehand will make your security lock installation smoother and safer.

- Measuring tape
- Chisel
- Level
- Replacement lock (deadbolt, keypad, or smart model)
5 Steps to Installing Security Locks
Step 1: Remove the Old Lock
Use a screwdriver to remove the interior and exterior screws.
Take out the old latch or cylinder.
If you’re upgrading from a basic lock, note whether new holes or adjustments are required.
Step 2: Prepare the Door for a New Security Lock
Measure and mark where the new lock will be installed.
Drill new holes or enlarge existing ones to fit the new mechanism.
Use a chisel to shape the strike plate recess in the door frame.
✅ Pro Tip: Keep everything level so your door closes smoothly.
Step 3: Install the New Lock Hardware
Insert the latch or bolt into the side of the door and screw it in place.
Fit the key cylinder and thumb turn (or keypad/smart module) through the holes.
Secure both sides tightly, ensuring the lock sits flush with the door.
For smart locks, follow the setup instructions for Wi-Fi and battery components.
Step 4: Attach the Strike Plate on the Door Frame
Align the strike plate with the lock’s bolt position.
Chisel a recess if necessary so it fits flat.
Secure it firmly with screws, ensuring smooth bolt movement.
Step 5: Test the Security Lock Installation
Close the door and lock it several times to check smooth movement.
Ensure it locks fully without resistance.
If you’ve fitted a smart or keypad lock, test all digital features too.
Tighten or adjust screws if the door or lock feels loose or misaligned.
