Is your 2012 Ford Fiesta displaying a “Low Battery Warning” for your key fob? It’s a common issue, even if it might seem surprising after just a year or two. Don’t worry, replacing the battery in your Ford Fiesta key fob is a simple task you can easily handle yourself. This guide will walk you through the process step-by-step, ensuring you get your key fob working perfectly again in no time.
The good news is that the 2012 Ford Fiesta key fob uses a readily available and inexpensive coin-type battery: the CR2032 3-volt lithium battery. You can find these batteries at most drugstores, supermarkets, and electronics stores.
Here’s how to replace the battery in your 2012 Ford Fiesta key fob, covering both the Integrated Keyhead Transmitter (IKT) and the Intelligent Access key (IA key) types:
For the Integrated Keyhead Transmitter (IKT):
- Locate the small recess on the back of your key fob.
- Carefully insert a flat object, like a small screwdriver or a coin, into this recess. Gently twist to separate the key blade from the fob.
- Use the flat object again to release the clips holding the two halves of the transmitter together. Carefully pry them apart.
- Now you’ll see the battery. Gently pry out the old CR2032 battery. Be careful not to touch any of the circuit board components with your tool.
- Insert the new CR2032 battery, making sure the side with the “+” symbol is facing upwards.
- Snap the two halves of the key fob transmitter back together until they are securely closed.
For the Intelligent Access key (IA key):
- On the sides of your Intelligent Access key fob, you’ll find push buttons. Press and hold these buttons simultaneously to release the battery cover. Carefully remove the cover.
- Remove the key blade from the fob.
- Look for a slot as indicated in your owner’s manual (if available, or similar to the linked guide in the original post). Insert a flat object into this slot and twist gently to separate the two halves of the transmitter.
- Carefully open the transmitter halves.
- Using a flat object, gently pry out the old battery.
- Install the new CR2032 battery with the “+” side facing downwards this time.
- Reassemble the two halves of the transmitter, ensuring they snap firmly together.
- Finally, re-insert the key blade.
Once you’ve completed these steps for your 2012 Ford Fiesta key fob type, the low battery warning should disappear, and your key fob should be working perfectly. Remember to dispose of the old battery responsibly according to your local regulations.
Replacing your 2012 Ford Fiesta Key Fob Battery is a quick and easy maintenance task that can save you a trip to the dealership. With a new CR2032 battery, you can regain full functionality of your keyless entry and start system and get back on the road with confidence.
