Experiencing issues with your 2016 Honda Pilot key fob after a battery replacement can be frustrating. You’ve likely encountered the dreaded “key fob low battery” warning and taken the initiative to replace the CR2032 battery. However, if you’re now facing a non-responsive key fob, you’re not alone. Let’s troubleshoot this common problem.
One owner of a 2016 Honda Pilot recently encountered this exact scenario. After replacing the battery in one of their original key fobs (Fob A), it stopped working for locking/unlocking doors and opening the trunk. Interestingly, the key fob could still start the vehicle when physically pressed against the start button. The red indicator light on Fob A also failed to illuminate when buttons were pressed, unlike the working Fob B. Even reverting to the old battery didn’t resolve the issue.
So, what could be happening when your 2016 Honda Pilot key fob isn’t working after a battery replacement? Here are a few potential causes and troubleshooting steps:
1. Battery Issues:
- Check Battery Orientation: Ensure the CR2032 battery is installed correctly with the positive (+) side facing upwards. A reversed battery can prevent the key fob from functioning.
- New Battery Quality: While you’ve used a new Duracell battery, try another new CR2032 battery from a different pack or brand to rule out a faulty battery. Sometimes, even new batteries can be defective.
- Battery Contact: Inspect the battery contacts inside the key fob. Make sure they are clean and making good contact with the battery. You can gently clean them with a cotton swab and a bit of rubbing alcohol if necessary.
2. Key Fob Unpairing (Less Likely):
- In most cases, simply replacing the battery should not cause the key fob to unpair from your Honda Pilot. The fact that your key fob can still start the car when pressed against the start button suggests it’s still recognized by the vehicle’s immobilizer system. Unpairing is less likely the culprit here.
3. Key Fob Damage:
- Static Discharge: While rare, static electricity during battery replacement could potentially damage the key fob’s internal electronics.
- Accidental Damage: Inspect the key fob for any signs of physical damage, such as cracks or signs of impact, which might have occurred during the battery replacement process.
4. Red Light Indicator:
- The red light not illuminating on button presses is a significant clue. It strongly suggests a power issue or internal malfunction within the key fob itself.
Troubleshooting Steps:
- Double-Check Battery: Re-verify battery orientation and try a different new CR2032 battery.
- Clean Contacts: Gently clean battery contacts inside the fob.
- Test Fob B: Confirm that your other key fob (Fob B) is still working correctly to rule out any vehicle-related issues.
- Professional Assistance: If none of the above steps work, it’s likely that Fob A may have an internal issue or require reprogramming. Contacting a professional locksmith specializing in car key fob replacement or your local Honda dealer is advisable. They can diagnose the issue, reprogram the existing fob if possible, or provide a 2016 Key Fob Replacement if necessary. HondaCare contracts may potentially cover key fob issues, so it’s worth checking your contract details.
Replacing a 2016 Honda Pilot key fob can sometimes be the only solution. While battery issues are the most common cause of key fob problems, internal malfunctions can occur. For reliable 2016 key fob replacement and programming services, especially if troubleshooting fails, consult a professional to ensure proper functionality and avoid further complications.
