A key fob is a small, handheld device that allows you to lock, unlock, and start your car remotely. Over time, the battery in your key fob will wear down, and you’ll need to replace it.
Replacing the battery in your key fob is a simple and straightforward process, and in this guide, we’ll walk you through the steps to do it.
Step 1: Determine the Type of Battery Your Key Fob Uses.
Before you begin, you’ll need to determine the type of battery your key fob uses. Most key fobs use either a CR2032 or a CR2025 battery. You can usually find this information in your car owner’s manual or by doing a quick online search. Alternatively, you can open your key fob and check the battery type printed on the battery.
Step 2: Purchase the Replacement Battery.
Once you know the type of battery your key fob uses, you’ll need to purchase a replacement battery. You can find replacement batteries at most electronics stores or online retailers. Make sure to purchase a high-quality battery from a reputable brand to ensure that it lasts as long as possible.

Step 3: Open Your Key Fob.
To replace the battery in your key fob, you’ll need to open it up. The process for doing this will vary depending on the make and model of your key fob. Some key fobs have screws that need to be removed, while others have clips that can be pried open with a small screwdriver. Consult your car’s owner’s manual or do an online search to find the specific instructions for your key fob.
Step 4: Remove the Old Battery.
Once you have your key fob open, you’ll need to remove the old battery. Most key fobs have a small clip or spring that holds the battery in place. Carefully remove the clip or spring and slide out the old battery.
Step 5: Insert the New Battery.
With the old battery removed, you can now insert the new one. Make sure to insert it with the positive (+) side facing up. Some key fobs have a diagram showing the correct orientation of the battery. If your key fob doesn’t have a diagram, you can usually find one online.
