What Is a Key Fob, and Why Does the 2017 Ford Explorer Require Battery Replacement?
A key fob is a remote control device that allows users to access a vehicle without using a physical key. It typically communicates with the car’s locking system through radio signals.
According to the National Institute of Standards and Technology (NIST), a key fob can be defined as a wireless device that uses cryptographic protocols to ensure secure access to a car and may also offer additional functions such as remote start and vehicle tracking.
The 2017 Ford Explorer utilizes a key fob to enhance convenience and security for its users. The key fob allows users to lock and unlock doors, initiate the engine start, and activate the car’s alarm. Its functionality relies on an internal battery, which powers the fob and its related features.
Additional definitions from sources like the Society of Automotive Engineers (SAE) describe key fobs as electronic components that facilitate keyless entry systems, providing both security and comfort features.
Key fobs may require battery replacement due to frequent use, environmental factors, or battery age. Low battery power can lead to diminished range and decreased functionality.
Statistics indicate that key fobs typically last about 2-3 years before requiring a battery change, as stated by the Automotive Technology Research Institute. Neglecting this can lead to user inconvenience and potential security risks.
A malfunctioning key fob can lead to access issues, increased vulnerability to theft, and a decreased overall user experience. Users may find themselves locked out of their vehicles or unable to use remote features.
The implications extend to the economy, as inefficient key fob technologies may lead to increased vehicle theft rates. Environmental impacts occur through the disposal of electronic components.
For mitigating key fob battery issues, manufacturers recommend regular checks and timely replacements. The Battery Manufacturers Association suggests following the manufacturer’s guidelines for battery longevity and replacement intervals.
Employing techniques like using rechargeable batteries and environmental considerations in battery disposal can further help. Additionally, advancements in key fob technology, such as solar-powered options, can offer sustainable solutions.
How Can You Tell When Your 2017 Ford Explorer Key Fob Battery Needs Replacing?
You can tell when your 2017 Ford Explorer key fob battery needs replacing by observing a few key signs, such as reduced range of the key fob, delayed response when pressing buttons, or a warning message on your vehicle’s dashboard.
Reduced range: If you notice that you must be closer to your vehicle to unlock or start it, the battery may be weakening. Key fobs typically have a range of about 30 feet. A longer distance signifies a stronger battery.
Delayed response: If there is a noticeable lag when you press the buttons on the key fob, the battery is likely failing. A functioning key fob should respond immediately when the button is pressed.
Warning message: Some modern vehicles, including the Ford Explorer, may display a warning message when the key fob battery is low. This notification often appears on the dashboard, indicating that the battery needs attention.
Visual inspection: If you open the key fob and see corrosion or rust around the battery terminal, it is time to replace the battery. Corrosion can hinder the connection and reduce functionality.
Frequency of battery replacement: Key fob batteries generally last about two to three years, depending on usage. If your key fob is older or used frequently, consider replacing the battery proactively.
These signs indicate that it’s advisable to replace the battery to ensure the key fob operates effectively. Regular maintenance of the key fob can save you time and avoid any inconvenience related to vehicle access.
