What Battery Does a 2017 Ford Fusion Key Fob Take?
The 2017 Ford Fusion key fob uses a CR2032 battery, a common lithium coin cell battery readily available at most hardware stores, pharmacies, and online retailers.
Expert Insight: “Always opt for a high-quality CR2032 battery from a reputable brand,” advises John Miller, a seasoned automotive electrician. “While cheaper alternatives may be tempting, they often have a shorter lifespan, leading to more frequent replacements.”
