Prepare the Key Fob
The first step in changing the car key battery in your Toyota Corolla is to prepare the key fob for battery replacement. Follow these steps:
- Locate the key release button on your key fob. This button allows you to remove the key from the fob for easier access.
- Press and hold the key release button, then slide the key out of the fob.
- Once the key is removed, look for a small seam along the edge of the key fob. This is where you will insert the screwdriver to open the fob.
- Insert the screwdriver into the seam and gently pry open the key fob. Be careful not to apply too much force to avoid damaging the fob.
Now that the key fob is open, you can proceed to the next step of changing the car key battery.
Replace the Key Battery
With the key fob open, you can now replace the old battery with a new one. Follow these steps:
- Locate the battery compartment inside the key fob. The battery is usually held in place by a small metal clip or a plastic holder.
- Use the tweezers or small pliers to carefully remove the old battery from the compartment. Take note of the battery’s orientation, as you will need to insert the new battery in the same way.
- Insert the new battery into the compartment, ensuring that it is positioned correctly.
- If there is a metal clip holding the battery in place, carefully secure it back in position.
Now that the new battery is in place, it’s time to assemble the key fob and test the key.
