Experiencing a “Key Not Detected” message on your Ford F-150 dashboard can be frustrating, especially when your key fob is right in your pocket. This common issue often signals a low battery in your key fob, and knowing how to address it can save you from unexpected inconveniences. Drawing from personal experience and readily available resources, this guide will walk you through understanding the battery type for your F-150 key fob and what to do when you encounter this warning.
Many vehicle owners might expect a CR2032 battery in their key fobs, as it’s a common type for garage door openers and some car remotes. However, for the Ford F-150, particularly models like the 2023 XLT ER, the key fob requires a different battery. It uses a CR2450 battery. This information is crucial because using the wrong battery type can prevent your key fob from working correctly.
Encountering a “Key Not Detected” message, similar to the experience with a previous vehicle, serves as a clear indicator that your key fob battery is likely nearing the end of its life. Proactive battery replacement at this stage is a smart move to avoid being stranded with a non-functional key fob. Waiting until the fob completely stops working can lead to unnecessary delays and frustration.
To confirm the correct battery type and potentially learn about the replacement procedure, consulting your Ford F-150 owner’s manual is always recommended. The manual provides specific details for your vehicle model, ensuring you have the right information at hand. Screenshots from the owner’s manual clearly indicate the CR2450 battery requirement for the F-150 key fob.
In conclusion, when you see a “Key Not Detected” warning in your Ford F-150, especially after about a year of ownership, consider changing the key fob battery. Remember to use a CR2450 battery for replacement. Keeping this information in mind can be a helpful quick reference, saving you time and trouble when your F-150 key fob battery needs changing.
