A dead key fob battery can leave you stranded. This guide provides everything you need to know about the battery for your Ford Explorer key fob, from identifying the correct battery type to step-by-step replacement instructions and advanced troubleshooting tips.
Understanding Your Ford Explorer Key Fob Battery
Your Ford Explorer key fob relies on a small but crucial battery to function. Knowing the right battery type and how to maintain it is essential for a smooth driving experience. A failing battery can manifest as decreased range, intermittent functionality, or a completely unresponsive key fob.
Identifying the Correct Battery
Most Ford Explorer key fobs use a CR2032 battery. This is a common 3-volt lithium coin cell battery readily available at most stores. However, it’s always best to double-check your owner’s manual for the specific battery type recommended for your model year. Using the incorrect battery can damage your key fob.

How do you know if your battery for Ford Explorer key fob is dying? Several telltale signs indicate it’s time for a replacement. These include having to press the buttons multiple times to get a response, reduced key fob range, and the vehicle’s security system not responding at all. Sometimes, the vehicle might only start when the key fob is held very close to the start button.
Replacing Your Ford Explorer Key Fob Battery: A Step-by-Step Guide
Replacing the battery in your Ford Explorer key fob is a quick and easy process you can do yourself. Here’s a step-by-step guide:
- Locate the release button: Look for a small button or notch on your key fob. This is usually located on the side or back.
- Separate the key fob: Using a small flathead screwdriver or a key, gently pry open the key fob along the seam where the two halves meet. Be careful not to damage the plastic casing.
- Remove the old battery: Carefully remove the old CR2032 battery. You can use your fingernail or the flathead screwdriver to gently pry it out.
