Step-by-Step Guide to Replacing the Battery in Your Toyota Corolla Key Fob
Here’s a detailed, step-by-step guide:
- Locate the release button: On the back of your key fob, find a small button or switch. This is the release for the mechanical key hidden inside.
- Release the mechanical key: Press the release button and gently slide the key out of the fob.
- Open the key fob casing: With the mechanical key removed, you’ll see a small slot. Insert your flathead screwdriver into this slot and gently pry open the casing. Be careful not to use too much force, as you could damage the fob.
- Identify and remove the old battery: Inside, you’ll see the CR2032 battery. Carefully remove it, noting the position of the positive (+) side.
- Insert the new battery: Place the new CR2032 battery in the compartment, ensuring the positive (+) side is facing the same direction as the old battery.
- Reassemble the key fob: Align the two halves of the casing and press them together firmly until you hear a click, indicating the fob is securely closed.
- Test the key fob: Press the lock, unlock, and panic buttons on your key fob to ensure it’s working correctly. If the buttons don’t respond, recheck the battery installation.
