If you have a hard-wired doorbell and it stops working, chances are there is a loose or broken wire in the button itself. Whether you are making repairs or replacing the unit all together, it is necessary to remove the existing button. Removing a doorbell button is a straightforward process. Doorbells attach simply to a home, although the securing screws might be hidden. Replacement doorbell buttons and doorbell systems are available at home improvement centers.

Remove a nonworking doorbell to check for loose wires.

Step 1

Turn off the power to the doorbell unit if you have a wired door bell. The circuit breaker is in your electrical panel box. Find the correct circuit breaker and turn it off.

Step 2

Find the screws securing the doorbell to the wall or door jamb. There is a screw above the doorbell button and one below it. If you do not see any screws, slip the blade of a utility knife between the seam of the front and side of the doorbell. Pry the front cover away and access the retaining screws.

Step 3

Remove the doorbell retaining screws with a Phillips-head screwdriver. Pull the doorbell away from the wall enough so you can access the wires from behind. If you have a wireless doorbell, there are no wires.

Step 4

Turn the two screws securing the wires to the back of the doorbell counterclockwise with a Phillips-head screwdriver. Remove the doorbell completely from the wall.
