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 situation often points to a common culprit: a low key fob battery. Like many modern vehicles, the Ford F-150 relies on a battery-powered key fob for convenient access and operation. Knowing the correct battery type and recognizing the signs of a low battery can save you from unexpected inconveniences.
Many might assume that the F-150 key fob, like many garage door openers and some other car fobs, uses the widely available CR2032 battery. However, for the Ford F-150, including models like the 2023 XLT ER, this is not the case. It’s crucial to know that the Ford F-150 key fob requires a CR2450 battery. This slightly larger battery ensures reliable performance and sufficient power for your key fob’s functions. Using the wrong battery type can lead to improper function or a poor fit.
Recognizing the early warning signs of a weakening key fob battery is key to preventing lockout situations. The “Key Not Detected” message appearing on your dashboard while you are in the vehicle is a primary indicator. This message suggests that the fob is struggling to communicate with your F-150 due to low power. Just like in the experience shared by a Ford F-150 Lightning owner, ignoring this warning can lead to complete key fob failure shortly after. Proactive battery replacement upon seeing this message is highly recommended.
To ensure you have the correct battery and understand its placement, consulting your Ford F-150 owner’s manual is always a good first step. The manual provides specific details about your vehicle’s key fob, including the battery type and replacement instructions. Screenshots from the owner’s manual clearly indicate the CR2450 battery and offer visual guidance for battery replacement.
Being informed about your F-150 key fob battery, specifically the CR2450 type, and heeding warning signs like the “Key Not Detected” message will help you maintain reliable access to your vehicle. Keeping a spare CR2450 battery on hand can also be a practical measure to avoid being caught off guard by a dead key fob battery.
