Indeed, at this point, you’re wondering how to install a buzzer door lock. Suppose you’re going the do-it-yourself (DIY) route and want to put this device yourselves; following the easy steps below will allow you to install your buzzer door lock easily.

Installing a Buzzer Door Lock

This type of lock is the one you commonly see as apartment door buzzers or those used for businesses. While these locks might look overly complicated to install, following our simple step-by-step guide will help you install them quickly and easily.

What you need

  1. A screwdriver
  2. Manual for the new buzzer door lock/wiring diagram
  3. Mounting brackets

Step 1: Ensure The Power is Disconnected

Before working on anything that runs on electricity, ensure your previous device is disconnected from the power source. You can also turn off the power source going into that specific area of the house to prevent any accidents.

Step 2: Uninstall The Existing Doorbell


If you have an existing doorbell you want to replace, the first step would be to uninstall it.

Start by unscrewing the face plate, then remove the wires. Be careful not to damage the cables if you plan to use the doorbell again.

Step 3: Put the Wires Through The Mounting Bracket


An electric door buzzer needs wires to function correctly. After screwing the mounting bracket, ensure the cables pass through the frame smoothly. Any damage to the wires will cause different problems for the device, so handle them with care.

Step 4: Connect The Wires to The Adapter


The adapter serves as the relay for the power. Connecting the wires to the adapter lets you relay the power from the source to your buzzer door lock.

After securing the cables through the mounting bracket, connect them to the adapter to turn them into live wires.

You can also refer to your wiring diagram if you feel lost on what to put where. These diagrams usually come with your device, so connecting them is easy.

Step 5: Screw The Buzzer In Place

The last thing you should do to ensure a complete door buzzer system installation is to put the buzzer in a secure and sturdy spot. Using your mounting bracket as a guide, you should be able to screw the device in place easier.
