The 2019 Ford Fiesta key fob typically uses a CR2032 3-volt lithium coin battery. This is the standard replacement battery for the four-button remote used on most Fiesta models from that era. If your key is a proximity smart key, the internal battery situation is different, but the common replaceable fob uses the CR2032.
Battery type and compatibility
Understanding the exact battery helps you prepare for a DIY replacement and avoids ordering the wrong part. The standard Fiesta remote you’ll find in most markets relies on a CR2032 coin cell. Some regions and variants may have small differences, so it’s a good idea to check the inside of the fob’s battery cover or your vehicle’s manual if you’re unsure.
To replace the battery yourself, you’ll typically use a single CR2032 3V lithium button cell and reassemble the fob so it functions like new. If the vehicle doesn’t respond after replacement, the issue could lie with the fob’s seal, the electronics, or the car’s receiver, not just the battery.
If you’re planning to replace the battery, here are the steps you’ll follow:
- Buy a fresh CR2032 3V lithium battery from a reputable brand.
- Open the key fob by gently prying along the seam with a small flat tool, taking care not to damage the housing.
- Remove the old battery, noting the correct orientation (+ side up is common, though you should verify inside the cavity).
- Insert the new CR2032 with the correct polarity and reseal the fob by pressing the halves together until they click.
- Test the remote buttons to confirm full function before leaving the battery compartment open or unsealed.
With the correct battery installed and the fob properly reassembled, the remote should operate normally. If problems persist after replacement, consider the possibility of a faulty fob or a need for reprogramming at a dealership or by an automotive locksmith.
Regional variations and additional notes
In most regions, the CR2032 is the standard battery for the 2019 Fiesta key fob. Some very early or region-specific variants might use a different coin cell such as CR2025, though CR2032 is far more common for this model year. When in doubt, check the label inside the fob’s battery cover or consult your owner’s manual or a Ford dealer to confirm the correct battery type for your exact market and trim.
Summary
For a 2019 Ford Fiesta, the typical replaceable key fob battery is a CR2032 3V lithium coin cell. Replacing it is a straightforward DIY task—open the fob, swap in the new battery with proper orientation, and reassemble. If remotes still fail after replacement, seek professional assistance to diagnose possible issues with the fob or vehicle receiver.
