If you’ve replaced the battery and the key fob remains unresponsive, the problem might be more complex than a simple dead battery. The key fob itself might be faulty, or there could be an issue with your car’s keyless entry system.
“I’ve seen cases where the key fob’s internal circuitry gets damaged,” says John Miller, a certified automotive technician with over 20 years of experience. “Sometimes, it’s a simple fix, but other times, you may need a new key fob entirely.”
