Just replaced the battery in your Honda CRV 2016 key fob and it’s still not working? Don’t worry, you’re not alone. This is a common issue, and often, the solution is simpler than you might think. Modern Honda vehicles, including the 2016 CRV, are designed to alert you on the instrument panel when your key fob battery is nearing the end of its life. Typically, a key fob battery needs replacing when its voltage drops to around 3.0 volts. A brand new battery should ideally measure between 3.3 and 3.4 volts. So, if your old battery was indeed around 3.0 volts, it was likely time for a change.
However, if you’ve just installed a fresh battery and your key fob remains unresponsive, the problem might not be the battery itself. A frequent cause after a Honda Crv 2016 Key Fob Battery Replacement is a simple issue with the electrical connection between the battery and the key fob’s terminals. Let’s explore some troubleshooting steps to get your key fob working again.
Troubleshooting Your Key Fob Battery Replacement
If your Honda CRV 2016 key fob is not functioning after a battery replacement, here’s a systematic approach to diagnose and fix the problem:
Verify Battery Voltage
First, even if the battery is brand new, it’s wise to double-check its voltage. Use a voltmeter to measure the voltage of the new battery. It should ideally read above 3.2 volts, and preferably around 3.3 or 3.4 volts. If the voltage is significantly lower, you might have received a faulty new battery. Ensuring you have a healthy battery is the first step in resolving key fob issues.
Check for Connection Problems with the Battery
The most common reason for a failed key fob after a battery swap is a poor electrical connection. This can happen due to a slight misalignment or obstruction during the battery replacement process.
To address this, try what’s known as a “rinse and repeat” replacement cycle:
- Re-open the key fob: Carefully disassemble your Honda CRV 2016 key fob again.
- Re-install the new battery: Remove and then re-insert the new battery, ensuring it is correctly placed in the battery slot.
- Inspect for plastic protectors: Crucially, check both sides of the new battery to ensure there isn’t a thin plastic protector film covering either contact side. These protectors are sometimes present on new batteries and can block the electrical connection if not removed.

Sometimes, simply reseating the battery and ensuring clean contacts can resolve intermittent connection issues that occurred during the initial battery swap.
Inspect and Adjust Fob Battery Contacts
If the “rinse and repeat” method doesn’t work, the next step is to meticulously inspect the metal contacts within the key fob that are meant to connect with the battery.
- Carefully examine the contacts: Look closely at the small metal tabs or springs inside the key fob that press against the battery’s positive and negative terminals.
- Check for bent contacts: Sometimes, these contacts can get slightly bent or displaced during a battery replacement. If a contact is bent, it might not be making solid contact with the battery, especially if the new battery is of a slightly different size or thickness than the original. This could explain why the old battery might seem to work while the new one doesn’t.
- Use a voltmeter to test contacts: With the battery installed, use a voltmeter to check if the fob’s contact points are actually receiving voltage from the battery. This will confirm if the battery is making electrical contact with the fob’s circuitry.

By carefully inspecting and potentially gently adjusting these contacts, you can often restore a proper electrical connection and bring your Honda CRV 2016 key fob back to life after a battery replacement.
Conclusion
Replacing the battery in your Honda CRV 2016 key fob should be a straightforward process. However, if you encounter issues afterward, remember to systematically check the battery voltage, ensure clean and secure battery connections, and inspect the fob’s internal contacts. In many cases, these simple steps can resolve the problem and save you a trip to the dealership. If you continue to experience problems after trying these troubleshooting steps, it might be time to seek professional assistance to diagnose potential issues with the key fob itself or your vehicle’s receiver system.
