What Type of Battery Does a 2017 Toyota Corolla Key Fob Use?

How to Replace the Battery in a 2017 Toyota Corolla Key Fob
Replacing the battery in your 2017 Toyota Corolla key fob is a quick and easy process that you can do yourself. Here’s a step-by-step guide:
- Locate the Key Fob’s Release Button: Look for a small button or switch on the back of your key fob. This button releases the physical key.
- Release the Physical Key: Press the release button and gently slide the physical key out of the key fob.
- Open the Key Fob: With the physical key removed, you should see a small slot or indentation. Use a flat-head screwdriver or a coin to pry open the key fob casing at this slot.
- Remove the Old Battery: The CR2032 battery will be visible. Carefully remove it by gently prying it up from the side. Avoid touching the battery’s flat surfaces.
- Install the New Battery: Insert the new CR2032 battery into the compartment, making sure the positive (+) side faces up.
- Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click.
- Reinsert the Physical Key: Slide the physical key back into its slot until it locks in place.
- Test Your Key Fob: Make sure your key fob is functioning correctly by locking and unlocking your Corolla several times.
Pro Tip from John Smith, Senior Automotive Technician: “When replacing your key fob battery, be gentle when prying open the casing to avoid any damage. If you’re unsure about any step, consult your owner’s manual or seek professional assistance.”
