Step-by-Step Guide to Installing a Digital Door Lock on Your Main Door

A digital door lock enhances security and convenience by eliminating the need for traditional keys. Whether you’re upgrading from a manual lock or installing a new one, the process requires careful measurement, proper alignment, and secure installation. This guide will walk you through each step to ensure a smooth and successful installation.

Step 1: Choose the Right Digital Door Lock

Before installation, ensure that the digital door lock you’ve chosen is compatible with your door type. Consider factors such as:

• Door thickness – Most digital locks fit doors between 35mm to 60mm
• Lock type – Decide between mortise locks, rim locks, or deadbolt locks based on your security needs.
• Access methods – Choose from fingerprint, passcode, RFID card, face recognition, or mobile app control.
• Power source – Digital locks run on batteries, so check if your lock requires AA batteries or a built-in rechargeable battery.

Step 2: Gather Your Tools

For installation, you’ll need the following tools:

• Screwdriver (Phillips and flathead)
• Measuring tape
• Drill with drill bits
• Chisel and hammer (for mortise locks)
• Pencil or marker for marking drill points

Most digital door locks come with an installation template, making it easier to position and drill correctly.

Step 3: Remove the Existing Lock

If your door already has a lock installed, you’ll need to remove it first:

1. Unscrew and detach the doorknob or handle.
2. Remove the latch mechanism by unscrewing the strike plate from the door edge.
3. Clean the surface to ensure the new lock sits securely in place.

If you’re installing on a new door, skip this step and proceed with measuring and drilling.

Step 4: Measure and Mark the Drill Points

1. Use the installation template provided by the manufacturer to mark where to drill holes for the lock.
2. Ensure proper alignment with your door’s existing cutouts (if any).
3. Mark the positions for the handle, keypad, and latch mechanism using a pencil.

Pro tip: Align the keypad height at a comfortable level (usually 100 to 120 cm from the floor).

Step 5: Drill Holes for the Lock and Screws

1. Drill the main hole (for the keypad or handle) at the marked position.
2. Drill a side hole on the door edge for the latch or mortise mechanism.
3. Drill screw holes for securing the lock in place.

If installing a mortise lock, you may need to chisel a slot into the door to fit the lock body properly.

Step 6: Install the Digital Lock Components

For Rim Locks and Deadbolts:

1. Insert the latch or bolt into the drilled hole on the door edge.
2. Secure it with screws and check if it moves smoothly.
3. Attach the front panel (keypad or fingerprint scanner) on the outside of the door.
4. Connect the internal mechanism on the inside of the door.
5. Fasten everything securely with the provided screws.

For Mortise Locks:

1. Insert the mortise body into the slot on the door edge.
2. Attach the front panel, ensuring the wiring is properly positioned.
3. Connect the rear panel and tighten all screws.
4. Install the handle or lever as instructed in the manual.

Pro tip: If the lock has a cable connection, ensure it is securely attached before closing the panels.

Step 7: Install Batteries and Set Up the Lock

1. Insert the required batteries (usually AA or rechargeable lithium batteries).
2. Turn on the lock and follow the manufacturer’s instructions for initial setup.
3. Set a master PIN code and register fingerprints, RFID cards, or mobile app access.

Step 8: Test the Lock

Before finalizing the installation, test all access methods to ensure the lock is functioning properly:

• Enter the passcode to check if the lock opens.
• Scan a fingerprint or RFID card if applicable.
• Try using the manual key override in case of emergency.
• Close the door and ensure the locking mechanism engages smoothly.

Step 9: Secure the Strike Plate and Final Adjustments

1. Align the strike plate on the door frame with the latch or bolt.
2. Drill pilot holes and screw the strike plate securely in place.
3. Check if the door closes smoothly and locks properly.

Pro tip: If the lock doesn’t close correctly, adjust the strike plate position slightly.

Step 10: Connect to Smart Features (Optional)

If your digital door lock has Wi-Fi or Bluetooth connectivity, set up the smart functions:

• Download the manufacturer’s mobile app.
• Pair the lock with your smartphone.
• Enable features like remote unlocking, access logs, and guest passcodes.
• Configure auto-lock and tamper alerts for added security.
