Experiencing a “Key Not Detected” message in your Ford vehicle can be frustrating, especially when your key fob battery is the culprit. It happened to me recently with my 2023 Ford F-150 Lightning, just about a year after purchase. Thinking it might be a common issue and wanting to share my experience, I realized many Ford owners might face this sooner than expected. Unlike some remotes that use CR2032 batteries, Ford key fobs often require a different type: the CR2450 battery.
It’s easy to assume all key fob batteries are the same, but using the wrong type can lead to improper function or damage. My owner’s manual clearly specifies the CR2450 for my key fob, a detail that could easily be overlooked. To help other Ford owners avoid confusion and ensure they have the right battery on hand, I’m sharing this information. Knowing the correct battery type is the first step in a smooth and quick replacement process.
For those who are used to the common CR2032 coin cell batteries, the CR2450 might be a surprise. It’s slightly larger and offers a different capacity, which is why Ford specifies it for optimal performance of your key fob. Checking your owner’s manual is always the best first step to confirm the exact battery your Ford key fob needs. This simple step can save you time and ensure you purchase the correct replacement battery.
So, if you encounter the dreaded “Key Not Detected” message in your Ford, don’t immediately assume there’s a major issue. It’s highly likely a simple battery replacement is all you need. Just be sure to grab a CR2450 battery for your Ford key fob to get back on the road quickly. Keeping a spare CR2450 battery on hand could also save you from future inconveniences.
