Experiencing a “Key Not Detected” message in your 2020 or newer Ford F-150 can be frustrating, especially when your key fob is right in your pocket. Many drivers might assume the key fob battery life should last longer than a year or two, but sometimes these things happen. Just like any electronic device, key fob batteries can occasionally fail sooner than expected. If you’re getting this warning, it’s a good idea to consider a battery replacement sooner rather than later to avoid being stranded.
One important thing to note for Ford F-150 owners is the type of battery your key fob requires. While many might expect a common CR2032 battery, similar to those used in garage door openers, the F-150 key fob actually uses a CR2450 battery. This is a slightly different size and capacity, so it’s crucial to use the correct replacement to ensure optimal performance and longevity of your key fob. Referring to your owner’s manual is always a good step to confirm this information and any specific instructions Ford provides.
To help other F-150 owners avoid confusion and quickly find the right information, remembering the CR2450 designation is key. A quick search for “CR2450 battery” will lead you to the correct replacements when you need to swap out your key fob battery. This simple piece of information can save you time and ensure you purchase the right battery for your 2020 and newer Ford F-150 key fob.
