Your Toyota Corolla key fob is more than just a convenient gadget; it’s your gateway to seamless vehicle access and security. From locking and unlocking doors remotely to potentially starting your car, this little device packs a punch. But what happens when your key fob stops working, you replace the battery, or you get a new one? Often, the answer is simple: reprogramming. As your trusted auto repair experts at Keyfobx.com, we’ll walk you through the process of 2017 Toyota Corolla Key Fob Programming, ensuring you can regain control without a trip to the dealership.
Understanding Your 2017 Toyota Corolla Key Fob
Before diving into programming, let’s appreciate what your 2017 Toyota Corolla key fob offers. It’s designed for convenience and security, communicating wirelessly with your vehicle to perform several functions:
- Remote Locking and Unlocking: The most basic function, allowing you to secure or open your car doors from a distance.
- Panic Button: A safety feature to trigger your car alarm in emergencies.
- Trunk Release: Opens the trunk without using your physical key (on some models).
These features rely on a small battery-powered transmitter within the fob that sends signals to your Corolla. Like any electronic device, issues can arise, necessitating reprogramming.
Battery Replacement for Your 2017 Corolla Key Fob
One common reason your key fob might stop working is a dead battery. Luckily, replacing it is a straightforward process. Here’s how to open your 2017 Toyota Corolla key fob and change the battery:
-
Locate the Release Latch: Most 2017 Corolla key fobs have a small release latch. This might be a button or a tiny slider, often located on the side or bottom of the fob.
-
Release the Emergency Key (If Applicable): Some models have a hidden physical key inside. If you see a latch near the key ring loop, release it to remove the emergency key. This might also help expose the opening seam of the fob.
-
Pry the Fob Open: Once the emergency key is removed or you’ve located the release latch, you’ll see a small seam running along the edge of the key fob. Use a small flathead screwdriver or a coin to gently pry the fob halves apart at this seam. Be careful not to apply excessive force to avoid damaging the plastic casing.
-
Identify the Battery: Carefully open the fob. You’ll see a small circuit board and the battery. Note the battery type and its orientation (+ and – sides). Most 2017 Toyota Corolla key fobs use a CR2032 battery.
-
Replace the Battery: Gently remove the old battery. You might need to use the tip of a pen or a small screwdriver to nudge it out. Install the new CR2032 battery, ensuring the correct orientation.
-
Reassemble the Fob: Carefully snap the two halves of the key fob back together until they are securely closed. Ensure there are no gaps.
-
Test the Fob: Try using the buttons on your key fob to lock and unlock your car. If it works, you’re all set! If not, reprogramming might be necessary.

-
Get Inside Your Corolla: Enter your 2017 Toyota Corolla and close all doors. Ensure you are in the driver’s seat.
