Is your 2017 Ford Explorer key fob battery showing signs of running low? Learn how to replace it, extend its life, and get answers to common FAQs!
Signs of a Low Key Fob Battery
Is your keyless entry system not working as it should? It could be a sign that your key fob battery is running low. The key fob, also known as a remote or transmitter, is a handy device that allows you to lock or unlock your vehicle remotely, control the alarm system, and even start the engine. However, when the battery starts to lose its power, you may experience some common signs that indicate it’s time for a replacement.
Diminished Range of Remote Keyless Entry
One of the first signs of a low key fob battery is a diminished range of the remote keyless entry. Normally, you should be able to lock or unlock your vehicle from a reasonable distance. However, if you find yourself needing to be closer to your car for the key fob to work, it’s a clear indication that the battery is weakening. This can be frustrating, especially when you’re in a hurry and need quick access to your vehicle.
Difficulty Locking or Unlocking the Vehicle
Another sign that your key fob battery is running low is difficulty locking or unlocking the vehicle. When the battery is fresh, a simple press of a button is all it takes to secure or open your car. However, as the battery loses power, you may notice that it takes multiple attempts or extra force to lock or unlock the doors. This inconvenience can be a hassle, especially in situations where you need immediate access to your vehicle.
Malfunctioning Panic Button
The panic button on your key fob is designed to provide you with a sense of security in emergency situations. When pressed, it activates the car’s alarm system, attracting attention and potentially scaring off intruders. However, if your panic button is not functioning properly, it could be a sign that the key fob battery is dying. You may notice that pressing the panic button doesn’t elicit the expected response, or it may not work at all. This can be alarming, as you rely on this feature for your personal safety.
To ensure the optimal performance of your key fob and avoid any untimely battery failures, it’s essential to know how to replace the key fob battery properly.

Tips for Extending Key Fob Battery Life
Are you tired of constantly replacing the battery in your key fob? It can be frustrating and inconvenient, especially when you’re in a hurry. But fear not! There are some simple tips and tricks you can follow to extend the life of your key fob battery. Let’s dive in and explore these strategies.
Avoiding Excessive Button Presses
One of the main reasons why key fob batteries die prematurely is due to excessive button presses. Every time you press a button on your key fob, it sends a signal to your vehicle. This constant communication between the fob and the car drains the battery over time. So, how can you avoid this?
First and foremost, try to minimize unnecessary button presses. Many people have a habit of repeatedly pressing the buttons on their key fob, even when they are out of range or not near their vehicle. This habit can significantly reduce the battery life. Instead, only press the buttons when you are in close proximity to your car and actually need to lock or unlock it.
Additionally, be mindful of accidental button presses. It’s easy for the buttons on your key fob to get pressed when it’s in your pocket or purse. To prevent this, consider using a protective case or cover for your key fob. These cases can help prevent accidental button presses and prolong the battery life.
Keeping the Key Fob Away from Electronics
Did you know that electronics can interfere with the signal between your key fob and your car? This interference not only affects the range of your keyless entry but can also drain the battery more quickly. To avoid this, it’s essential to keep your key fob away from other electronic devices.
Avoid placing your key fob near smartphones, tablets, or other devices that emit electromagnetic signals. These signals can disrupt the communication between the fob and the car, leading to a weaker signal and increased battery usage. Instead, designate a separate pocket or compartment for your key fob to minimize any potential interference.
Storing the Key Fob at Room Temperature
Believe it or not, temperature plays a significant role in the lifespan of your key fob battery. Extreme temperatures, whether hot or cold, can impact the performance and longevity of the battery. Therefore, it’s crucial to store your key fob at room temperature whenever possible.
Avoid leaving your key fob in direct sunlight or extreme heat, such as inside a hot car or near a heater. High temperatures can cause the battery to deteriorate more quickly, leading to a shorter lifespan. On the other hand, exposing your key fob to freezing temperatures can also negatively affect the battery’s performance.
If you live in an area with extreme temperatures, consider using a protective case or cover that offers insulation for your key fob. This can help regulate the temperature and protect the battery from the harsh elements.
