If your Honda key fob stops working or doesn’t unlock the doors, it’s usually because the small coin battery inside has run out. The good news is that changing it is very easy; you don’t need special tools or any technical skill. Most Honda models, such as the Accord, Civic, CR-V, and Pilot, use a CR2032 or CR2025 battery.
To change a Honda key fob battery, first press the release button and take out the metal key. Next, use a small screwdriver or the key itself to gently open the fob case. Remove the old battery and note which side faces up. Then, place the new battery in the same position with the positive (+) side up, snap the fob back together, and reinsert the metal key. Finally, press the buttons to test if it works. Following these steps takes only a few minutes and saves you a trip to the dealership.
Tools You’ll Need To Change a Honda Key Fob Battery
Before starting the car battery replacement process, gather a few basic tools:
- A small flathead screwdriver or coin.
- A new CR2032 or CR2025 battery (check your owner’s manual).
- A clean, soft cloth to protect the fob surface.
Once you have these ready, you can replace the battery in just a few easy steps.
Step-by-Step Process to Change Honda Key Fob Battery
Let’s go through the process step by step. The steps below apply to most Honda models, including Accord, Civic, CR-V, and Pilot.
Step 1: Locate the Key Release Button
On most Honda key fobs, there’s a small button or switch at the back. Press it to release the metal key inside the fob. Remove the key completely and set it aside. This step gives you access to the slot that helps open the fob case.
Step 2: Open the Key Fob Case
Use the tip of a small flathead screwdriver or the key you removed to gently pry open the fob. Insert it into the slot near the seam and twist slightly until the two halves of the key fob pop apart. Be careful not to use too much force, as you don’t want to damage the plastic.
Step 3: Remove the Old Battery
Inside the fob, you’ll see a small round battery held in place by clips. Gently lift the old battery out using the screwdriver tip or your fingernail. Note how it’s positioned; the positive (+) side should face up. This will help you place the new battery correctly.
Step 4: Insert the New Battery
Take the new CR2032 (or CR2025) battery and place it into the slot with the positive side facing up. Make sure it sits flat and snug under the clips. Avoid touching the battery surface with your fingers too much, as oils from your skin can affect its contact quality.
Step 5: Snap the Key Fob Back Together
Align the two halves of the key fob and press them together until you hear a snap. Make sure there are no gaps around the edges. Then, reinsert the metal key into its slot. The fob should now look and feel like new again.
Step 6: Test the Key Fob
Press the lock and unlock buttons to ensure everything works properly. If it doesn’t respond, reopen the fob and check if the battery is seated correctly or facing the right way. Once it works, you’re good to go.
When to Replace Your Honda Key Fob Battery
Your key fob battery powers all remote features, unlocking doors, starting the engine, and even opening the trunk. Over time, the small coin battery inside runs out of charge. You might notice your key fob working only when held close to the car, or not at all. Replacing the battery from the car service center restores full signal strength and ensures smooth, reliable use. It’s a simple fix that prevents the hassle of being locked out or unable to start your car.
You should replace your key fob battery as soon as you notice:
- The key fob buttons respond slowly or inconsistently.
- The light on the fob becomes dim or doesn’t flash.
- You have to press the button several times for it to work.
- The remote work is only for a short distance.
Most key fob batteries last around 2 to 3 years, depending on use. Replacing it before it dies completely saves you from being stuck with a non-working fob.
Conclusion
Changing your Honda key fob battery is one of the easiest car maintenance tasks you can do at home. With just a screwdriver and a few minutes, you can restore full function to your key fob and avoid dealership service costs.
