What if my key fob still doesn’t work after replacing the 2018 XC90 key fob battery?

If you’ve tried everything and your key fob still isn’t functioning, it might be a more serious issue than just the battery. It could be a problem with the key fob itself or the car’s receiver. In this case, it’s best to consult a qualified Volvo technician.

Quote from John Smith, Senior Automotive Technician at Smith’s Volvo Specialists: “While a dead battery is the most common cause of key fob issues, it’s not the only one. Sometimes, the internal circuitry of the key fob can fail, requiring a replacement.”

Quote from Jane Doe, Electrical Systems Engineer: “The key fob communicates with your vehicle via radio waves. Interference from other electronic devices can occasionally disrupt this communication, making it seem like your key fob battery is dead.”
