Experiencing problems with your 2016 Honda Pilot key fob after a battery change? You’re not alone. Many Honda Pilot owners encounter situations where their key fob malfunctions after a seemingly straightforward battery replacement. Let’s troubleshoot common issues and get your key fob working again.
You mentioned replacing the battery in your 2016 Pilot key fob (Fob A) after receiving a low battery warning. Now, it’s not working for basic functions like locking/unlocking doors or opening the trunk. However, it does start the car when pressed against the start button. The red light on Fob A also isn’t illuminating when buttons are pressed, unlike your working Fob B.
Let’s explore potential causes and solutions for your non-functional key fob.
Possible Reasons Your Key Fob Isn’t Working After Battery Replacement
Several factors could be at play here:
- Incorrect Battery Installation: While seemingly simple, it’s possible the CR2032 battery isn’t seated correctly in the key fob. Double-check the polarity (+ and – sides) and ensure the battery is firmly in place and making good contact. Even a slightly loose battery can prevent the fob from working.
- Faulty New Battery: Although you used a new Duracell CR2032, there’s a small chance the new battery itself is defective or drained. Try a different brand new CR2032 battery to rule out a faulty battery issue.
- Key Fob Circuitry Issue: Less likely, but possible, is that the key fob’s internal circuitry might have been damaged during the battery replacement process, or it may have simply failed. Static electricity discharge during handling could potentially harm sensitive components.
- De-synchronization (Less Likely in This Case): While key fobs can sometimes lose synchronization with the vehicle, the fact that your fob starts the car when pressed against the button suggests it’s still somewhat recognized by the system. Complete de-synchronization would likely prevent even push-button starting.
Troubleshooting Steps to Try
-
Re-inspect Battery Installation: Open the key fob again and carefully remove and re-insert the new CR2032 battery. Ensure it’s snug and properly oriented.
-
Try Another New Battery: Use a fresh CR2032 battery from a different pack or brand. This eliminates the possibility of a batch of faulty batteries.
-
Check for Debris or Corrosion: Inspect the battery contacts inside the key fob for any signs of dirt, debris, or corrosion. Clean gently with a soft, dry cloth if needed.
-
Test the Red Light Again: After re-installing a new battery, press the buttons on Fob A again. If the red light still doesn’t illuminate, it strongly indicates a problem beyond just the battery.
-
Consider Fob Programming (Less Likely but Possible): While less probable given your symptoms, Honda key fobs can sometimes require reprogramming if they completely lose power or communication. Check your Honda Pilot owner’s manual for key fob programming instructions. However, note that dealer programming might be necessary in some cases.
HondaCare Contract & Dealer Assistance
Since you have a HondaCare contract, this is definitely beneficial. If the troubleshooting steps above don’t resolve the issue, your next best step is to contact your Honda dealer. Explain the situation, mentioning that you replaced the key fob battery and now it’s not working correctly, despite still starting the car via push-button. Inquire if this issue would be covered under your HondaCare contract.
The lack of red light illumination on the fob is a key symptom to highlight to the dealer, as it suggests a potential hardware problem within the key fob itself.
Moving Forward
Start by re-checking the battery and trying a fresh replacement. If the red light remains off and the fob functions remain limited, contacting your Honda dealer and leveraging your HondaCare contract is the most practical approach to resolve this 2016 Honda Pilot key fob issue. They can diagnose the fob, determine if it needs replacement or reprogramming, and advise on warranty coverage.
