Before you begin, it’s important to gather all the tools and supplies you will need to change the car key battery in your Toyota Corolla. Here’s a list of what you’ll need:

• Replacement battery: Make sure you purchase the correct battery for your Toyota Corolla key fob. Check the owner’s manual or consult a local dealership to find out the specific type of battery you need.

• Tweezers or small pliers: These tools will help you remove the old battery from the key fob and insert the new one.

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:

1. Locate the key release button on your key fob. This button allows you to remove the key from the fob for easier access.
2. Press and hold the key release button, then slide the key out of the fob.
3. 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.
4. 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:

1. Locate the battery compartment inside the key fob. The battery is usually held in place by a small metal clip or a plastic holder.
2. 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.
3. Insert the new battery into the compartment, ensuring that it is positioned correctly.
4. 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.

Assemble the Key Fob

Before you can start using your key fob again, you need to reassemble the key fob. Follow these steps:

1. Line up the two halves of the key fob and press them together until they snap into place. Make sure the edges are flush and the fob is securely closed.
2. With the key fob assembled, insert the key back into the fob until it clicks into place.

Now that the key fob is fully assembled, you can move on to testing the key to ensure it is working properly.

Test the Key

After changing the car key battery in your Toyota Corolla, it’s important to test the key to make sure everything is functioning correctly. Follow these steps:

1. Stand near your Toyota Corolla and press a button on the key fob. The car should respond by either unlocking the doors, opening the trunk, or activating the panic alarm, depending on which button you pressed.
2. If the key fob does not work, double-check that the battery is inserted correctly and that the key fob is properly assembled.
3. If the key still does not work, you may need to replace the battery again or seek assistance from a professional.
