Experiencing rapid battery drain in your 2020 Honda CRV key fob can be frustrating. If you’re finding yourself replacing your key fob battery more often than expected, you’re not alone. Many Honda CRV owners have encountered similar issues, leading to inconvenience and questions about battery life and key fob performance. Understanding the correct battery size and potential causes of this problem is the first step to finding a solution.
Understanding the 2020 Honda CRV Key Fob Battery
The 2020 Honda CRV key fob, like many modern car keys, relies on a small, circular battery to operate its remote functions. The standard battery size for the 2020 Honda CRV key fob is a CR2032 battery. This 3V lithium battery is widely available and known for its reliability in low-power devices. A multimeter reading of 3.3V on a CR2032 battery should indicate a fully charged battery. However, even with a seemingly full charge, your key fob might fail to operate.
Common Causes of Rapid Battery Drain in CRV Key Fobs
Several factors can contribute to your 2020 Honda CRV key fob battery draining quickly:
Battery Quality and Source
The quality and source of your CR2032 batteries can significantly impact their lifespan. Batteries purchased from unreliable sources, especially online marketplaces with third-party sellers, might be old, counterfeit, or previously used. Some batteries may suffer from “passivation,” a condition where a high resistance layer forms inside the battery, reducing performance even if the voltage reading appears normal. Purchasing batteries from reputable brick-and-mortar stores ensures better quality control and fresher stock.
Key Fob Malfunction
While less common, a malfunctioning key fob can also cause rapid battery drain. If the key fob’s internal circuitry has a fault, it might constantly draw power even when not in use, leading to premature battery depletion.
Starting Your 2020 CRV with a Dead Key Fob
If your 2020 Honda CRV key fob battery dies completely, you can still start your vehicle. Honda vehicles typically have a backup system that allows you to start the car by holding the key fob close to the start button. This utilizes an RFID chip in the fob that doesn’t require battery power. Consult your 2020 Honda CRV owner’s manual for the exact procedure for emergency starting with a dead key fob battery.
Conclusion
Dealing with a 2020 Honda CRV key fob that eats through batteries can be annoying, but understanding the potential causes can help you address the issue effectively. Ensure you are using the correct CR2032 battery size, purchase batteries from reputable retailers to avoid low-quality or old stock, and consider the possibility of a key fob malfunction if battery drain persists. By taking these steps, you can minimize key fob battery problems and maintain reliable access to your Honda CRV.
