A dead battery in your Toyota key fob can be a real pain, leaving you stranded and unable to unlock your car. Luckily, changing the battery is a quick and easy fix you can do yourself at home. This comprehensive guide will walk you through the simple steps to get your key fob back in action in no time.
What You’ll Need:
- A new CR2032 battery (check your owner’s manual to be sure)
- A small flat-head screwdriver or a plastic pry tool
Steps to Change the Battery in Your Toyota Key Fob:
-
Locate the release button: Look for a small button or switch on the back of your key fob. This button releases the mechanical key, which you’ll need to access the battery compartment.
-
Release the mechanical key: Press the release button and gently slide the mechanical key out of the fob.
-
Open the key fob: With the mechanical key removed, you should see a small slot or seam where the two halves of the fob connect. Carefully insert the tip of your flat-head screwdriver or pry tool into the slot and gently pry open the fob. You might hear a slight click when the two halves separate.
-
Remove the old battery: Once the fob is open, you’ll see the battery inside. It’s typically held in place by a small clip or pressure. Gently lift the old battery out, taking note of its orientation.
-
Install the new battery: Insert the new CR2032 battery into the compartment, making sure the positive (+) side faces up (the same way the old battery was positioned).
-
Reassemble the key fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating they’re securely closed.
-
Test the key fob: Press a button on your key fob to make sure it’s working properly. If it’s not, double-check that the battery is correctly installed and the fob is properly closed.
Still Having Trouble?
If you’ve replaced the battery and your Toyota key fob is still not working, there might be other issues at play. Here are a few things to consider:
- Check the battery: Ensure the new battery you installed is not dead. You can test it with a battery tester if you have one.
- Inspect the key fob: Examine your key fob for any physical damage, such as cracks or loose buttons, that could be affecting its functionality.
- Try reprogramming the key fob: In some cases, you might need to reprogram your key fob after replacing the battery. Refer to your owner’s manual for instructions on how to do this.
