How to Add Another Doorbell Chime: A Complete DIY Guide
Is your doorbell only ringing in one part of the house? Maybe you’ve got a large home, a basement bedroom, or a backyard office where the chime never seems to reach. Adding another doorbell chime is a smart, affordable fix that can make your home safer and more convenient. Whether you’re trying to hear the doorbell from the garage, the master bedroom, or a home gym, this guide will show you exactly how to add another doorbell chime—step by step.
You don’t need to be an electrician to do this. With basic tools and a little patience, most homeowners can install a second chime in under an hour. This guide covers everything from choosing the right chime to wiring it safely and testing the final setup. We’ll also explore wireless alternatives if running wires sounds too complicated. By the end, you’ll have a fully functional dual-chime system that works seamlessly with your existing doorbell.
Why Add Another Doorbell Chime?
Before diving into the installation, it’s helpful to understand why adding a second chime is such a useful upgrade. Many homes—especially older ones—were built with a single chime unit located near the front door. While this works fine for small spaces, it becomes a problem in larger homes or multi-level layouts.

For example, if you’re in the basement doing laundry or in a second-floor bedroom with the windows closed, you might miss the doorbell entirely. This isn’t just an inconvenience—it can be a security risk. Visitors, delivery drivers, or emergency personnel might leave because they think no one is home.
Adding a second chime ensures that no matter where you are in the house, you’ll hear when someone’s at the door. It’s especially helpful for:
- Families with young children or elderly relatives who may not hear a distant chime
- Home offices where you’re focused on work and might not notice a soft ring
- Homes with thick walls, soundproofing, or background noise (like TVs or fans)
- People who work night shifts and sleep during the day
Beyond practicality, a second chime can also improve your home’s value. It’s a small upgrade that shows attention to detail and modern convenience—something homebuyers appreciate.
Types of Doorbell Chimes: Mechanical vs. Digital
Before you buy a new chime, it’s important to know what type of system you currently have. Most doorbells fall into two categories: mechanical (traditional) and digital (electronic).
Mechanical Chimes
These are the classic “ding-dong” chimes you might remember from older homes. They use electromagnets to strike metal bars or bells, creating a two-tone sound. Mechanical chimes are simple, reliable, and usually operate on low-voltage AC power (typically 8–24 volts).
If your current chime makes a distinct “ding” followed by a “dong,” it’s likely mechanical. These systems are easy to expand because they use simple wiring and don’t require complex programming.
Digital Chimes
Digital chimes use electronic circuits and speakers to play recorded sounds—like chimes, melodies, or even voice alerts. They’re quieter, more customizable, and often come with features like volume control or multiple sound options.
Digital chimes also run on low-voltage power but may require specific compatibility with your doorbell button and transformer. Some digital systems use proprietary protocols, so adding a second unit might require a matching model or a compatible add-on.
To determine your system type, check the chime unit itself. Mechanical chimes often have visible metal bars or a small hammer mechanism. Digital ones usually have a plastic cover with a speaker grill and may have buttons for settings.
Choosing the Right Additional Chime
Once you know your system type, it’s time to pick a compatible second chime. Here’s what to consider:
Compatibility
The most important factor is compatibility. If you have a mechanical system, you can usually add any standard mechanical chime from the same brand or a universal model. For digital systems, check the manufacturer’s website for compatible add-on units.
For example, if you have a Ring doorbell with a Ring Chime, you can add a second Ring Chime Pro or a compatible third-party unit. Similarly, brands like Honeywell, Nutone, and Heath Zenith offer expandable systems.
Power Requirements
Make sure the new chime matches the voltage of your existing system. Most doorbells use 16V AC transformers, but some older systems may use 8V or 24V. Check the label on your transformer (usually located near your electrical panel or in the attic) and the specs on the chime you’re buying.
Using a chime with the wrong voltage can damage the unit or cause it to underperform. If you’re unsure, consult the manufacturer or a licensed electrician.
Sound and Volume
Consider where you’ll install the second chime. If it’s in a bedroom or quiet area, you might want a softer tone. For a garage or basement, a louder, more attention-grabbing sound may be better.
Some digital chimes let you adjust volume or choose different sounds. Mechanical chimes have a fixed tone, but you can find models with louder or softer strikes.
Wireless vs. Wired Options
If running new wires seems daunting, wireless chimes are a great alternative. These plug into standard outlets and sync with your existing doorbell button via radio frequency or Wi-Fi.
Wireless chimes are easy to install—no drilling or fishing wires required. However, they rely on batteries or constant power, and signal range can be limited by walls or interference.
Popular wireless options include the Ring Chime, Amazon Echo Dot with doorbell alerts, and GE Wireless Doorbell Extender. These are ideal for renters or homes where wiring isn’t practical.
Tools and Materials You’ll Need
Before starting, gather all the necessary tools and materials. Having everything ready will make the process smoother and safer.
Basic Tools
- Screwdrivers (Phillips and flathead)
- Wire strippers
- Voltage tester (non-contact type recommended)
- Electrical tape
- Wire nuts (usually included with the chime)
- Pliers (optional, for tightening connections)
Materials
- Additional doorbell chime (compatible with your system)
- Low-voltage wire (18–22 gauge, typically 2-conductor)
- Wire labels or colored tape (to mark wires)
- Mounting screws (usually included with the chime)
- Wire staples or clips (if running new wire through walls)
Safety Gear
- Safety glasses
- Work gloves
Always prioritize safety. Even though doorbell systems use low voltage, they’re still connected to your home’s electrical circuit. A shock is unlikely, but it’s better to be cautious.
Step-by-Step Installation Guide
Now that you’re prepared, let’s walk through the installation process. We’ll cover both wired and wireless options, but this section focuses on adding a wired second chime—the most reliable and permanent solution.
Step 1: Turn Off the Power
The first and most important step is to turn off the power to your doorbell system. This prevents accidental shocks and protects your equipment.
Locate your home’s main electrical panel (breaker box). Look for a breaker labeled “doorbell,” “chime,” or “transformer.” If you can’t find a dedicated breaker, turn off the main power to be safe.
Once the breaker is off, use a non-contact voltage tester to confirm that power is disconnected. Touch the tester to the wires at the existing chime unit. If it doesn’t beep or light up, the power is off.
Pro Tip: Take a photo of the wiring before disconnecting anything. This will help you remember how everything was connected.
Step 2: Remove the Existing Chime Cover
Unscrew the cover of your current doorbell chime. Most covers are held in place by two screws at the top and bottom. Gently pull the cover away from the wall.
Inside, you’ll see two or three wires connected to terminals labeled “Front,” “Trans,” and sometimes “Rear” (if you have a second doorbell button). The “Front” terminal connects to the front door button, and “Trans” connects to the transformer.
Use your photo or wire labels to identify each wire. If the wires aren’t labeled, use colored tape to mark them (e.g., red for “Front,” black for “Trans”).
Step 3: Disconnect the Wires
Loosen the terminal screws and carefully remove the wires. Be gentle—these wires are thin and can break if pulled too hard.
Set the old chime aside. You’ll reuse the wires to connect the new chime.
Step 4: Run New Wire to the Second Location
This is the most challenging part of the installation. You’ll need to run a new 2-conductor wire from the existing chime location to where you want the second chime.
Common locations for a second chime include:
- Upstairs hallway
- Master bedroom
- Basement
- Home office
- Garage
To run the wire:
- Use a fish tape or flexible drill bit to guide the wire through walls, ceilings, or baseboards.
- Drill small holes in studs or joists as needed.
- Secure the wire with staples or clips every few feet to prevent sagging.
- Avoid sharp bends or pinching the wire.
If you’re not comfortable drilling or fishing wires, consider hiring a handyman or using a wireless chime instead.
Step 5: Install the New Chime
Once the wire is in place, mount the new chime to the wall using the included screws. Make sure it’s level and secure.
Strip about 1/2 inch of insulation from the ends of the new wire. Connect the two wires to the terminals on the new chime. Most chimes are not polarity-sensitive, so it doesn’t matter which wire goes where.
Tighten the terminal screws firmly, but don’t over-tighten—this can damage the terminals.
Step 6: Connect the New Chime in Parallel
Now, go back to the original chime location. You’ll connect the new chime in parallel with the existing one. This means both chimes will receive power when the doorbell button is pressed.
Here’s how:
- Take the two wires from the new chime and connect them to the same terminals as the original wires.
- For example, if the original “Front” wire is connected to the “Front” terminal, connect one wire from the new chime to the same terminal using a wire nut.
- Do the same for the “Trans” terminal.
You’ll now have three wires connected to each terminal: the original wire, the new chime wire, and a short “pigtail” wire that connects to the terminal screw.
Pro Tip: Use a wire nut to join the three wires, then connect the pigtail to the terminal. This ensures a secure connection.
Step 7: Reattach the Chime Cover and Restore Power
Once all connections are secure, reattach the cover to the original chime. Make sure no wires are pinched or exposed.
Go back to the breaker box and turn the power back on. Wait a few seconds for the system to reset.
Step 8: Test the System
Press the doorbell button and listen. Both chimes should ring at the same time. If only one rings, double-check your wiring.
If neither chimes work, turn the power off again and verify all connections. Use your voltage tester to ensure power is reaching the transformer and chimes.
Troubleshooting Common Issues
Even with careful installation, problems can occur. Here’s how to fix the most common issues:
Only One Chime Rings
This usually means the new chime isn’t properly connected in parallel. Check that both chimes are wired to the same terminals. If one chime is wired in series, it may block the signal.
Chimes Don’t Ring at All
First, confirm the power is on. Then check the transformer voltage with a multimeter. If it’s below 12V, the transformer may be overloaded or failing.
Also, verify that the doorbell button is working. Press it firmly and listen for a click. If there’s no click, the button may be faulty.
Weak or Intermittent Sound
This could be due to loose connections or low voltage. Tighten all wire nuts and terminal screws. If the problem persists, consider upgrading to a higher-capacity transformer.
Wireless Chime Not Syncing
For wireless units, make sure the chime is within range of the doorbell button (usually 100–300 feet). Remove obstacles like metal walls or appliances that can block the signal.
Follow the manufacturer’s pairing instructions carefully. Some units require a specific sequence of button presses to sync.
Wireless Chime Installation (Alternative Method)
If running wires isn’t feasible, a wireless chime is a great alternative. Here’s how to set one up:
Step 1: Choose a Wireless Chime
Select a model that’s compatible with your doorbell. Many brands offer plug-in chimes that work with existing buttons.
Step 2: Plug In the Chime
Find an outlet near where you want the chime to be heard. Plug in the unit and follow the setup instructions.
Step 3: Sync with the Doorbell Button
Most wireless chimes sync automatically when you press the doorbell button. Some may require you to press a pairing button on the chime first.
Step 4: Test and Adjust
Press the button and confirm the chime rings. Adjust volume or sound settings as needed.
Wireless chimes are ideal for renters, apartments, or homes with complex wiring. Just remember to replace batteries regularly.
Maintenance Tips for Long-Term Performance
Once your second chime is installed, a little maintenance will keep it working smoothly:
- Clean the chime covers every few months to prevent dust buildup.
- Check wire connections annually for looseness or corrosion.
- Replace batteries in wireless units every 6–12 months.
- Test the system monthly to ensure both chimes are functioning.
