Intermittent Functioning: The key fob works sporadically, sometimes responding and sometimes not.
Warning Light on Dashboard: Some Corolla models display a “Key Fob Battery Low” warning on the dashboard.
No Response from Key Fob: The key fob fails to lock, unlock, or start your car altogether.

The 2014 Toyota Corolla key fob typically uses a CR2032 battery, a common type of lithium coin battery. These batteries are readily available at most supermarkets, electronics stores, and auto parts shops.

How to Replace Your Toyota Corolla 2014 Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your 2014 Toyota Corolla key fob is a quick and straightforward process that you can easily do yourself. Here’s a detailed guide:

Locate the Battery Compartment: On the back of your key fob, you’ll find a small release button or notch. Press the button or use a small flathead screwdriver to pry open the battery compartment.
Identify and Remove the Old Battery: Inside the compartment, you’ll see the CR2032 battery. Carefully remove the old battery by gently prying it up with your fingernail or the tip of a flathead screwdriver. Avoid using excessive force to prevent damaging the key fob.
Install the New Battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up. You should hear a slight click when the battery is properly seated.
Reassemble the Key Fob: Align the two halves of the key fob and press them together until you hear them snap back into place.

Troubleshooting Common 2014 Toyota Corolla Key Fob Issues

Even after replacing the battery, you might still face some issues with your key fob. Here are some common problems and how to troubleshoot them:

Key Fob Not Programming: After battery replacement, your key fob might need to be reprogrammed. You can usually find the programming instructions in your Corolla’s owner’s manual or online. If you’re unsure, it’s best to consult a qualified automotive locksmith or dealership.
Key Fob Still Not Working: If reprogramming doesn’t resolve the issue, there could be a more significant problem with your key fob’s internal circuitry or the car’s receiver. In this case, it’s best to seek professional assistance from a qualified automotive locksmith or dealership.
Key Stuck in Ignition: This issue is not directly related to the key fob battery. If your key is stuck in the ignition, it could be a problem with the ignition cylinder or the steering wheel lock mechanism. Again, it’s best to consult a qualified mechanic or dealership for assistance.
