Owning a 2012 Ford Mustang is an exhilarating experience, but even the most powerful muscle cars can be stopped in their tracks by a dead key fob battery.

Don’t worry, this is a common issue and easily fixed. This comprehensive guide will walk you through everything you need to know, from identifying the right battery to programming your new key fob.
Identifying the Right Battery for Your 2012 Ford Mustang Key Fob
Before you get started, it’s essential to know the correct battery type for your key fob. The 2012 Ford Mustang typically uses a CR2032 battery, a common type readily available at most stores that sell batteries.
Replacing the Battery: A Step-by-Step Guide
Replacing the battery in your 2012 Ford Mustang key fob is a straightforward process that most people can do themselves. Here’s a step-by-step guide:
- Locate the key slot: On the side of your key fob, you’ll find a small slot. This is where you’ll insert your key or a small flathead screwdriver.
- Open the key fob: Gently insert your key or screwdriver into the slot and twist or pry open the key fob. Be careful not to use excessive force, as this could damage the casing.
- Identify the battery: Inside the key fob, you’ll see the CR2032 battery.
- Remove the old battery: Carefully remove the old battery. Pay attention to the orientation of the positive (+) and negative (-) sides.
- Install the new battery: Insert the new CR2032 battery, ensuring the positive (+) side faces up, matching the orientation of the old battery.
- Close the key fob: Align the two halves of the key fob and press them together firmly until you hear a click.
- Test the key fob: Make sure all the buttons on your key fob are working correctly by locking and unlocking your car.
What If My Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your key fob is still not functioning correctly, you might need to reprogram it. Fortunately, programming a 2012 Ford Mustang key fob is relatively simple and can be done without special tools.
To reprogram your key fob, follow these steps:
- Get in your car and close all the doors.
- Insert your key into the ignition.
- Turn the ignition from the “Off” position to the “Run” position (where the dashboard lights come on) eight times in rapid succession. Do this within ten seconds.
- Turn the key back to the “Off” position. Your car should now be in programming mode, and you’ll hear a chime.
- Press any button on the key fob you want to program. You should hear a chime confirming successful programming.
- Repeat step 5 for each additional key fob you need to program.
- Turn the ignition to the “Run” position to exit programming mode.
