Common Types of Key Fobs
There are several different types of key fobs, and the process of changing the battery may vary slightly depending on the type. Some common types of key fobs include…
- Traditional Key Fobs: These fobs are separate from the vehicle’s key and usually have buttons to lock and unlock the car doors.
- Integrated Key Fobs: These key fobs have the key physically integrated into the fob and may have additional buttons for other functions.
- Smart Key Fobs: Also known as proximity keys, these fobs do not require physical contact with the vehicle to lock or unlock the doors and may even allow you to start the vehicle without inserting a key.
Identifying the Correct Battery
In order to switch the battery in your key fob, you must determine the proper type of battery. The majority of key fobs normally use a CR2032 or a CR2025 lithium coin cell battery. The battery type should be listed in your vehicle’s owner’s manual or printed on the back of the key fob itself.

Follow this step-by-step guide to change the battery in your key fob…
- Gather the necessary tools: You will need a small flathead screwdriver, a new battery (either CR2032 or CR2025), and a soft cloth or towel to protect the key fob from scratches.
- Open the key fob: Place the key fob on the soft cloth or towel, and use the flat head screwdriver to carefully pry open the fob’s case. Some fobs may have a small notch that helps you open it more easily. For integrated key fobs, you may need to remove the key first before opening the fob.
- Remove the old battery: Once the key fob is open, use the screwdriver to gently lift the old battery out of its compartment. Be careful not to touch any of the internal components or circuitry.
- Insert the new battery: Place the new battery into the compartment, ensuring that the positive side (+) is facing up. Gently press the battery down until it is securely in place.
- Close the key fob: Align the two halves of the key fob and gently press them together until they snap into place. Ensure that the fob is properly sealed to prevent any damage to the internal components.
- Test the key fob: After changing the battery, test the key fob to make sure it is functioning properly. Lock and unlock your vehicle or perform any other functions available on your key fob to ensure it is working correctly.

Prolonging Key Fob Battery Life
To prolong the life of your key fob battery, follow these tips and tricks:
- Limit unnecessary button presses: Avoid pressing the buttons on your key fob when it is not in use. Unintentional button presses can drain the battery more quickly.
- Store the key fob properly: Keep your key fob in a cool, dry place away from direct sunlight or high temperatures. Extreme temperatures can damage the battery and reduce its lifespan.
- Replace the battery before it dies: If you notice that your key fob is not working as efficiently as it once did, it may be time to replace the battery. Waiting until the battery dies completely can cause inconvenience and may even require reprogramming of the key fob.
Changing the battery in your key fob is a simple way to ensure your vehicle’s security and that it locks and unlocks. Never worry of being locked out of your vehicle!
