Your key fob is a marvel of modern technology, allowing you to lock, unlock, and even start your car remotely. But like all gadgets, it relies on a battery to function. Over time, this battery will lose its charge, leading to a decrease in range or responsiveness.

  • You need to be closer to your car for the key fob to work.

  • The key fob’s LED light is dim or doesn’t flash as brightly.

What You’ll Need:
