Locating the Battery Compartment
The battery compartment location varies depending on the key fob type. Some key fobs have a small release button or switch on the side, while others require you to pry open a section of the fob using a small flathead screwdriver or a key. Be careful not to damage the key fob during this process.

Once you have located the battery compartment, follow these steps to replace the battery:
- Gather your tools: You will need a small flathead screwdriver or a key (depending on your key fob type) and a new CR2025 or CR2032 battery (check your owner’s manual for the correct battery type).
- Open the battery compartment: Carefully insert the flathead screwdriver or key into the designated slot and gently pry open the compartment.
- Remove the old battery: Use the screwdriver or your fingernail to carefully remove the old battery.
- Insert the new battery: Place the new battery into the compartment, ensuring the positive (+) side is facing upwards.
- Close the battery compartment: Snap the compartment shut.
- Test the key fob: Check if the key fob functions correctly by locking and unlocking your car.
