Understanding Your Toyota Corolla Key Fob

While the specific design might vary slightly, the battery replacement process is generally similar for both types.
Gathering the Necessary Tools
Replacing the battery in your Toyota Corolla key fob requires minimal tools:
- A small flat-head screwdriver: This will be used to pry open the key fob.
- A new CR2032 battery: This is the standard battery size for most Toyota Corolla key fobs.
Locating the Battery Compartment
The battery compartment is usually located on the back of the key fob. It’s often marked with a small arrow or a symbol indicating the direction to open the compartment.
Opening the Key Fob
1. Locate the seam: Look for a seam running around the edge of the key fob. This is where the two halves of the fob are joined.
2. Insert the screwdriver: Carefully insert the flat-head screwdriver into the seam.
3. Gently pry open: Apply gentle pressure to pry the two halves of the key fob apart. Be careful not to force it, as this could damage the key fob.
Replacing the Battery
1. Remove the old battery: Once the key fob is open, you’ll see the old battery. It may be held in place by a small spring or clip. Gently remove the battery.
2. Insert the new battery: Carefully insert the new CR2032 battery into the compartment, making sure the positive (+) side is facing up.
3. Close the key fob: Once the new battery is in place, carefully snap the two halves of the key fob back together.
Testing the New Battery
After replacing the battery, it’s essential to test it to ensure it’s working correctly.
1. Press the buttons: Press each button on the key fob to see if they respond.
2. Test the keyless entry: If you have a smart key fob, try unlocking and locking your car using the keyless entry feature.
3. Check the remote start: If your key fob has remote start functionality, try starting your car remotely.
If everything works as expected, you’ve successfully replaced the battery in your Toyota Corolla key fob.
