The doorbell is how your parent hears the aide, the pharmacy delivery, or the family member who forgot a key. If the bedroom is at the back of the house, the button at the front may not reach them. That gap is what you are closing.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Step 1: Look at what is already on the wall

Open the chime box in the hallway or kitchen, if there is one. Turn off the power at the breaker before you remove any cover. Look for a transformer, the small box near the chime that steps the power down. Count the wires at the outside button. Write down what you see, and take a phone photo of the wires before you touch them.

Step 2: Decide what the chime has to do

Pick one target. You can ring at the bedside only, ring in the bedroom and the kitchen, or send an alert to a phone. A phone alert depends on your home internet, the brand's app, and a phone that is charged and nearby. Do not count on it alone if your parent is in a room with the door closed.

Step 3: The plug-in or battery path

If the goal is a second chime at the bedside, a wireless set is usually a do-it-yourself job. Check three lines in the manual before you buy: the range from button to receiver, the battery type in each unit, and whether the receiver plugs into an outlet or runs on batteries alone. Check whether the volume adjusts at the unit, so the sound level suits the room.

Mount the button where you will actually press it, not where it looks tidiest. Stand at the bedroom door with the door closed and press the button. Then stand in the bathroom and press it again. If you miss the chime twice, move the receiver closer to the bed or choose a set with a longer range.

Step 4: When the wiring is the job

Stop and hire the work if the chime box is missing, there is no transformer, the wires are scorched or brittle, or the wires do not match the two terminals on a new button. A new doorbell circuit, a new transformer, or a chime in a wall that has to be opened is usually work for an electrician. Ask for a written quote that says whether the transformer, the drywall patching, and any new wire run are included.

Step 5: Swapping only the outside button

If the chime works and the wires are sound, a new button is often a two-screw job. Match the wire count you wrote down. Power off at the breaker first. If the button has a light, check whether it takes a bulb or is a sealed unit.

What to compare before you buy

Compare the stated range, the battery life in the manual, whether the receiver has a volume control, and whether the button is rated for outdoor weather. Read what the manual says happens when a battery runs low. Write the model number on the inside of the chime cover so the next person can find it.

A chime does not replace a call button or a pendant. It covers the front door only. For the rest of the first two weeks at home, the Day 0 to Day 14 After Discharge plan walks through the order of things.
