Insert the screwdriver or coin into the notch and gently pry the fob open. You may need to apply a bit of pressure, but be careful not to damage the fob.
Step 2: Remove the Old Battery
Once the fob is open, you’ll see the old battery inside. Carefully remove the battery from the compartment, taking note of the positive (+) and negative (-) terminals.
If you’re unsure which terminal is which, consult your Toyota owner’s manual or look for markings on the battery compartment.
Step 3: Inspect the Old Battery (Optional)
If you have a battery tester or multimeter, now is a good time to check the old battery’s voltage. This can help you determine if the battery is truly dead or if there’s another issue with your key fob.
Compare the voltage reading to the manufacturer’s specifications to determine if the battery is still good.
Step 4: Install the New Battery
Take the new battery and insert it into the compartment, making sure to align the positive (+) and negative (-) terminals correctly.
Make sure the battery is securely seated and the terminals are not touching any metal components.
Step 5: Close the Key Fob
Once the new battery is installed, close the key fob by snapping it shut. Make sure it’s securely closed to prevent the battery from falling out. (See Also: What Causes Low Voltage In Car Battery)
