Step-by-Step Guide to Replacing the Key Battery
1. Locate the Key Fob Battery Compartment:
Identify the small, rectangular battery compartment on the back of your Toyota Highlander key fob. It is typically secured by a small screw or a snap-on cover.
2. Open the Battery Compartment:
Using the Phillips head screwdriver, carefully unscrew the screw securing the battery compartment cover. If your key fob has a snap-on cover, gently pry it open using the flat head screwdriver.
3. Remove the Old Battery:
Once the battery compartment is open, use the flat head screwdriver to gently pry out the old battery. Be careful not to damage the battery terminals or the surrounding components.
4. Clean the Battery Compartment:
Take a moment to clean the battery compartment using the clean cloth. Remove any dirt, dust, or corrosion that may have accumulated over time. This will ensure good contact between the new battery and the terminals.
5. Insert the New Battery:
Align the positive (+) and negative (-) terminals of the new battery with the corresponding terminals in the battery compartment. Gently press the battery into place, ensuring it is firmly seated.
6. Reattach the Battery Compartment Cover:
Once the new battery is in place, replace the battery compartment cover. If your key fob has a screw-on cover, carefully tighten the screw until it is secure. If it has a snap-on cover, gently press it back into place until it clicks.
7. Test the Key Fob:
Press the lock and unlock buttons on the key fob to verify that it is functioning correctly. If the buttons work as intended, the battery replacement was successful.
Additional Tips and Considerations:
- When purchasing a replacement battery, ensure it is the correct type (CR2032) and is compatible with your Toyota Highlander key fob.
