Understanding Your 2018 Prius Key Fob
Before we dive into the replacement process, let’s quickly cover the basics of your 2018 Prius key fob. This model typically uses a CR2032 battery, a common type found in many electronics. Knowing this beforehand will make your trip to the store much easier. There are two main types of key fobs for the 2018 Prius: the standard key fob with lock, unlock, and panic buttons, and the Smart Key system which allows for keyless entry and push-button start. Both use the same CR2032 battery.
Why Replace Your Key Fob Battery?
You’ll likely need a 2018 Prius Key Fob Battery Replacement if you’re experiencing reduced range, having to press the buttons multiple times to get a response, or if the car isn’t responding to your key fob at all. Sometimes, you might even see a low battery warning on your Prius’s dashboard. Ignoring these signs can lead to being locked out of your car, so it’s always better to be proactive.
2018 Prius Key Fob Battery Replacement: Step-by-Step
Here’s a simple, easy-to-follow guide for a 2018 Prius key fob battery replacement:
- Locate the release button: On the side of your key fob, you’ll find a small release button. Press it and gently separate the mechanical key from the fob.
- Open the fob: Use the mechanical key or a small flathead screwdriver to carefully pry open the key fob casing. There’s usually a small notch designed for this. Be gentle to avoid breaking the casing.
- Remove the old battery: Once open, you’ll see the CR2032 battery. Gently pry it out using your fingernail or the flathead screwdriver. Again, be careful not to damage the fob.
- Install the new battery: Insert the new CR2032 battery, making sure the positive (+) side is facing upwards, just like the old battery.
- Close the fob: Snap the two halves of the key fob casing back together. You should hear a click when it’s securely closed.
- Reinsert the mechanical key: Slide the mechanical key back into its slot.
- Test the fob: Try locking and unlocking your car to ensure the new battery is working correctly.
