There are several reasons you might need to access the inside of your doorbell button:
- Battery replacement: Wireless models use batteries that eventually die.
- Button sticking or unresponsive: Dirt, moisture, or wear can cause the button to jam.
- Weak or no chime sound: Corroded contacts or loose connections may be the culprit.
- Wiring inspection: For wired models, you may need to check connections or replace damaged wires.
- Upgrading or replacing: You might be swapping out an old unit for a new one.
No matter the reason, opening the button safely is the first step. Let’s get started.
Tools and Materials You’ll Need
Before you begin, gather these tools to make the process smooth and safe:
- Small flathead screwdriver (preferably 3–5 mm)
- Plastic pry tool or guitar pick (to avoid scratching)
- Butter knife (as a backup pry tool)
- Soft cloth or microfiber towel
- Cotton swabs
- Isopropyl alcohol (70% or higher)
- Replacement batteries (if needed)
- Flashlight (for better visibility)
- Safety gloves (optional, but recommended)
Avoid using metal tools like knives or large screwdrivers unless absolutely necessary—they can scratch or crack the plastic housing.
Step 1: Turn Off the Power
Safety comes first. Even though doorbell systems use low voltage, it’s still wise to cut power before handling any electrical components.
For Wired Doorbells
Most wired Honeywell doorbells connect to a transformer that steps down household voltage (usually 8–24V AC). To safely work on the button:
- Locate your home’s electrical panel (breaker box).
- Find the circuit labeled “doorbell,” “chime,” or similar. If unsure, turn off the main power or test with a non-contact voltage tester.
- Switch off the breaker.
- Test the doorbell button to confirm it no longer activates the chime.
Pro Tip: Take a photo of the breaker panel before turning anything off so you can easily restore power later.
For Wireless Doorbells
Wireless models like the Honeywell RDWL917A or RDWL311A run on batteries. To safely open them:
- Remove the batteries from the chime unit inside your home.
- Wait 30 seconds before proceeding—this ensures any residual charge dissipates.
Even though wireless buttons don’t have direct wiring, removing the chime batteries prevents accidental signals during handling.
Step 2: Identify Your Honeywell Doorbell Model
Honeywell makes several doorbell models, and the opening method can vary slightly. Knowing your model helps you follow the right steps.
Common Honeywell doorbell button models include:
- RDWL917A: Wireless, battery-powered, sleek rectangular design.
- RDWL311A: Wireless, compact, often used with smart chimes.
- T955A: Wired, traditional round or rectangular button.
- IS6500: Wired, modern design with LED indicator.
Check the back or bottom of the button for a model number. If it’s faded, search online using the chime unit’s model number—many buttons are paired with specific chimes.
Example: If your chime says “RDWL917A-2,” the matching button is likely the same model.
Step 3: Remove the Doorbell Button from the Wall
Before opening the button, you’ll need to detach it from the wall plate.
For Screw-Mounted Buttons
Most wired models are secured with screws:
- Use a Phillips or flathead screwdriver to remove the mounting screws.
- Gently pull the button away from the wall.
- Note how the wires are connected—take a photo for reference.
- Disconnect the wires by loosening the terminal screws or unclipping connectors.
Tip: Label the wires (e.g., “Front,” “Trans”) with tape if you’re unsure which goes where.
For Snap-On or Adhesive-Mounted Buttons
Wireless models often use adhesive pads or snap onto a base:
- For adhesive mounts: Gently wiggle the button side to side to loosen the glue.
- For snap-on bases: Look for release tabs on the sides or bottom. Press them while pulling the button away.
Avoid pulling too hard—these clips can break.
Step 4: Open the Honeywell Doorbell Button Casing
Now comes the main event: opening the button itself.
Look for Hidden Screws or Clips
Some models have screws hidden under stickers, rubber feet, or decorative covers.
- Check the back or sides for small screws.
- Peel back any rubber feet—they often conceal screws.
- Inspect for tamper-resistant stickers that may hide fasteners.
If you find screws, remove them with the appropriate screwdriver.
Pry Open the Casing (No Screws)
Most Honeywell buttons use plastic clips to hold the front and back together. Here’s how to open them safely:
- Place the button face-down on a soft cloth to protect the surface.
- Insert a plastic pry tool or flathead screwdriver into the seam between the front and back.
- Start at the bottom or side—avoid the button area to prevent damage.
- Gently twist the tool to create a small gap.
- Work your way around the edge, releasing clips one by one.
- Once all clips are loose, lift the front cover off.
Important: Do not force it. If it won’t open, double-check for hidden screws or clips.
Example: Opening the RDWL917A
The RDWL917A has no visible screws. To open:
- Use a plastic spudger or guitar pick.
- Insert it at the bottom edge, near the button.
- Slowly pry upward while moving left and right.
- The front will pop off after 3–4 clips release.
Step 5: Inspect and Clean Internal Components
With the casing open, you can now see the internal parts.
Check the Button Mechanism
Look for:
- Stuck or worn button contacts.
- Dirt, dust, or corrosion on metal parts.
- Broken or loose springs.
Use a cotton swab dipped in isopropyl alcohol to gently clean the contact points. Let it dry completely before reassembling.
Inspect Wiring (Wired Models)
For wired buttons:
- Check that wires are securely connected.
- Look for frayed insulation or corrosion.
- If damaged, trim and strip the wire ends, then reconnect.
Tip: Use electrical tape to secure loose connections temporarily.
Replace Batteries (Wireless Models)
If your model uses batteries:
- Remove the old batteries.
- Insert new ones, matching the polarity (+ and –).
- Use high-quality alkaline batteries for longer life.
Avoid mixing old and new batteries.
Step 6: Reassemble the Doorbell Button
Once you’ve cleaned or repaired the internals, it’s time to put everything back together.
Align the Front and Back
- Place the front cover over the back, aligning the clips.
- Press firmly around the edges until you hear or feel the clips snap into place.
- Start at one side and work your way around.
Caution: Don’t press directly on the button—apply even pressure to the frame.
Reattach to the Wall
- Reconnect the wires to the terminals (for wired models).
- Tighten the screws securely but don’t overtighten.
- Mount the button back onto the wall plate.
- Secure with screws or snap into place.
Step 7: Restore Power and Test
Now that everything is back in place:
For Wired Models
- Turn the breaker back on.
- Wait 10–15 seconds for the system to reset.
- Press the doorbell button and listen for the chime.
