Tools and Materials You’ll Need

Step-by-Step Instructions
Step 1: Safety First
Turn off the power to the doorbell at the electrical panel. This is a crucial safety precaution to prevent any electrical shocks.
Step 2: Remove the Old Doorbell
Locate the screws holding the doorbell in place and remove them. Carefully pull the doorbell away from the wall. Disconnect the wires from the terminals on the back of the doorbell.
Step 3: Prepare the Wires
Strip about 1/2 inch of insulation from the ends of the wires. Twist the exposed copper wires together to form a pigtail.
Step 4: Connect the New Doorbell
Connect the pigtail to the terminals on the back of the new doorbell, matching the colors of the wires (red to red, black to black). Secure the wires with electrical tape.
Step 5: Mount the New Doorbell
Place the new doorbell over the mounting holes on the wall and secure it with the screws.
Step 6: Test the Doorbell
Turn the power back on and press the doorbell button. The doorbell should chime or beep, indicating that it’s working properly.
