Experiencing problems with your 2006 Honda Accord key fob? It’s a common frustration when your keyless entry system becomes unreliable. Often, the first suspect is the key fob battery. This guide will walk you through troubleshooting steps, focusing on the 2006 Accord Key Fob Battery and other potential causes for a malfunctioning remote.
Many 2006 Honda Accord owners encounter situations where their key fob becomes intermittent or completely stops working. You might press the lock or unlock button and sometimes it responds, sometimes it doesn’t. This inconsistency can be irritating and lead you to believe the key fob battery is dying. While a low battery is a frequent culprit, it’s not always the sole reason.
Let’s explore the steps to diagnose and fix your 2006 Accord key fob issues, starting with the battery and moving to other potential problems.
Checking and Replacing Your 2006 Accord Key Fob Battery
The most straightforward fix, and often the first thing to try, is replacing the battery in your 2006 Accord key fob. Here’s how to check and replace it:
-
Open the Key Fob: Locate the small notch on the side of your key fob. Using a small flathead screwdriver or a coin, gently pry open the fob casing. Be careful not to scratch the plastic.
-
Identify the Battery Type: Once open, you’ll see the battery. Note the battery type and number. For the 2006 Honda Accord key fob, it typically uses a CR1620 or CR1616 3V lithium coin cell battery. It’s always best to double-check the marking on your old battery to ensure you get the correct replacement.
-
Remove the Old Battery: Carefully remove the old battery. You might be able to pry it out with your fingernail or the small screwdriver. Pay attention to the battery’s orientation (+ side up or down) before removing it – this is crucial for correct installation of the new battery.
-
Clean the Battery Terminals: Even if they look clean, gently wipe the battery terminals inside the key fob with a clean, dry cloth or a cotton swab. This removes any potential residue or corrosion that could hinder battery contact.
-
Install the New Battery: Insert the new battery, ensuring it’s in the correct orientation (matching the orientation of the old battery). It should snap into place.
-
Close the Key Fob: Carefully snap the key fob casing back together until it’s securely closed.

After replacing the 2006 Accord key fob battery, test the remote functions (lock, unlock, panic button) near your vehicle. If it works, problem solved! However, if you’re still experiencing issues, or if the key fob worked only briefly after a battery change, the problem might be something else.
Further Troubleshooting Steps if the New Battery Doesn’t Fix the Issue
If a fresh 2006 Accord key fob battery didn’t solve your remote problems, here are other potential causes and troubleshooting steps to consider:
1. Key Fob Terminal Corrosion or Damage
Even after cleaning, inspect the metal terminals inside the key fob for any signs of corrosion or physical damage. If the terminals are bent, heavily corroded, or broken, they may not be making proper contact with the battery, even a new one. In this case, the key fob itself might need replacement.
2. Key Fob Reprogramming
Sometimes, even with a new battery, the key fob might need to be reprogrammed to your 2006 Honda Accord. The reprogramming process essentially re-syncs the key fob’s signal with your car’s receiver.
Here’s a general method for reprogramming a 2006 Honda Accord key fob (always consult your owner’s manual for the most accurate procedure):
- Sit in the driver’s seat and close all doors.
- Insert the key into the ignition.
- Turn the ignition key to the “ON” position (just before starting the engine) and then back to the “OFF” position quickly. Repeat this three times (ON-OFF-ON-OFF-ON-OFF). Leave the key in the ignition.
- Quickly press and hold the “LOCK” button on the key fob.
- While holding the “LOCK” button, press the “UNLOCK” button once.
- Release both buttons. The car doors should lock and unlock automatically to indicate successful programming mode.
- Press the “LOCK” button on each key fob you want to program. The doors should lock and unlock after each successful fob programming.
- Turn the ignition key to the “ON” position to exit programming mode.
- Test all programmed key fobs to ensure they are working correctly.
It’s noted in the original user’s experience that reprogramming worked temporarily. If you find your 2006 Accord key fob needs reprogramming repeatedly, it suggests a deeper underlying issue.
3. Car Battery Issues
While you mentioned your car battery tested fine, it’s worth quickly revisiting. A weak car battery, even if it seems “good,” can sometimes cause intermittent electrical problems, including key fob malfunctions. Ensure your car battery terminals are clean and securely connected. If your car battery is old (3+ years), consider having it load-tested again at a different auto parts store for a second opinion.
4. Fuse Problems
As you suspected, fuses are crucial for electrical system operation. Locate your 2006 Honda Accord’s fuse box (usually under the dashboard or in the engine compartment – check your owner’s manual for the exact location). Identify the fuse related to the keyless entry system or power door locks. Inspect the fuse to see if the wire inside is broken or burnt. If blown, replace it with a fuse of the exact same amperage rating.
- Caution: Never replace a fuse with a higher amperage rating, as this can cause serious electrical damage.
Even if a fuse appears visually intact, it can sometimes be faulty. Try swapping it with a fuse of the same rating from a less critical system (like the interior lights) to test. If the key fob starts working after a fuse replacement, then a blown fuse was the problem.
5. Receiver or Wiring Issues
If none of the above steps resolve the 2006 Accord key fob issue, the problem might lie with the car’s keyless entry receiver or the wiring connecting it. The receiver is responsible for picking up the signal from your key fob. If it’s faulty, or if there’s a wiring problem, the signal won’t be properly received, regardless of the key fob battery or programming.
This type of issue is more complex to diagnose and usually requires professional automotive electrical troubleshooting.
When to Seek Professional Help
If you’ve tried replacing the 2006 Accord key fob battery, reprogramming, checking fuses, and you’re still having problems, it’s time to consult a professional. A qualified mechanic or your local Honda dealership can diagnose more complex issues like receiver malfunctions, wiring problems, or deeper electrical system faults.
Don’t let key fob frustration get you down. By systematically checking the 2006 Accord key fob battery, considering other common causes, and knowing when to seek expert help, you can get your keyless entry system working reliably again.
