How to Change the Battery in a Ford Key Fob?

To determine when to replace your key fob batteries, wait for a notification on your vehicle’s instrument cluster or display screen indicating the battery is low. Once you receive this message, refer to the following guide to replace the batteries promptly.
- Please remove the key blade. Depending on the model of your Ford, you may need to pull the blade out manually or use a release button.
- Use a flat screwdriver to pry open the key fob. To proceed, insert the end of the screwdriver into the side of the key where the key blade usually sits. Then, remove the cover carefully to reveal the battery. If your model requires pulling out the key to open it, you can use a small coin instead. Insert the coin into the key’s gap and twist it to remove the cover.
- To remove the battery, use a screwdriver to pry it out gently. Due to its flat and smooth surface, the battery may be difficult to remove. The screwdriver as a pry bar will work for both key fob models.
- To make the key fob work, please replace the battery. Ensure the new battery is inserted in the same position as the previous one, with the plus side facing up. Inserting the battery upside down will prevent the key fob from working correctly.
What Will Happen if I Choose Not to Replace the Battery in My Key Fob?

If the battery of your Ford vehicle dies completely, remote access will no longer be possible. Some Ford models have emergency keys that can be used to enter the vehicle. However, physical keys can be lost, stolen, or copied. Thieves can easily enter and steal the vehicle if they obtain your physical key.
Key fobs are increasingly popular as a replacement for traditional keys because they are cheaper to replace if lost or stolen, and key fob programming is easy. Even a basic battery can power them for an extended period, but Ford is working on new technology that would allow key fobs to be powered by magnetic fields transmitted between readers and antennas, eliminating the need for batteries.
