Your 2018 Ford Explorer key fob has suddenly stopped working? Don’t panic, this is a fairly common issue, and you’re in the right place to find out why. We’ll cover everything from simple fixes you can try at home to more complex problems that might require professional help.
Why is My 2018 Ford Explorer Key Fob Not Working?
There are several reasons why your 2018 Ford Explorer key fob might be acting up. It could be something as simple as a dead battery, or it could be a more serious issue like a faulty key fob or a problem with your vehicle’s receiver. Let’s explore some of the most common culprits.
Dead Key Fob Battery: The Usual Suspect
The most frequent cause of a non-responsive key fob is a dead battery. Key fobs are constantly sending and receiving signals, and this drains the battery over time. You might notice the range of your key fob decreasing before it completely stops working. This is a good indication that the battery is nearing its end. Replacing the battery is a quick and inexpensive fix, often solving the problem entirely. You can find information on replacing your specific battery by searching for something like “2015 Ford Explorer limited key fob battery.” If you’re unsure, consult your owner’s manual or a local auto parts store.
Key Fob Programming Issues: Out of Sync
Sometimes, the key fob can lose its programming and become desynchronized with your vehicle. This can happen after a battery change or for seemingly no reason at all. Reprogramming the key fob is usually a straightforward process, and you might be able to do it yourself following the instructions in your owner’s manual. However, some cases require professional diagnostic tools. For more information on programming, you can check out resources like those related to 2012 Ford Explorer key fob programming.
Faulty Key Fob: Internal Damage
If a new battery doesn’t solve the problem and reprogramming isn’t successful, the key fob itself might be damaged. Internal components can wear out or become damaged from drops or exposure to moisture. In these cases, replacing the key fob is usually the best solution.
Receiver Issues: The Car’s Perspective
In some cases, the problem isn’t with the key fob but with the receiver in your vehicle. The receiver is responsible for detecting the signal from the key fob and unlocking or starting the car. If the receiver is malfunctioning, it won’t be able to recognize the signal, even if the key fob is working perfectly. This is a more complex issue that requires professional diagnosis and repair.
Troubleshooting Your 2018 Ford Explorer Key Fob
Here are some steps you can take to troubleshoot the issue:
- Try the spare key fob: If you have a spare key fob, see if it works. If the spare key fob functions correctly, it points to a problem with the original key fob rather than the vehicle’s receiver.
- Check the key fob battery: Replace the battery with a fresh one, even if you think it might still have some life left. You can often find helpful resources online, like articles about the 2018 Ford Explorer sport key fob battery.
- Try reprogramming the key fob: Consult your owner’s manual for instructions on how to reprogram the key fob. You might find that resources related to programming other Ford models, like the 2018 Ford Focus ST car new key fob programming, can also offer helpful insights.
- Check for physical damage: Examine the key fob for any signs of physical damage, such as cracks, broken buttons, or water damage.
- Check the car battery: A weak car battery can sometimes interfere with the key fob’s functionality. Ensure your car battery is in good working order.

When to Seek Professional Help
If none of the troubleshooting steps work, it’s time to seek professional help. A qualified automotive technician can diagnose the problem using specialized diagnostic tools and recommend the appropriate course of action. This is especially important if you suspect a problem with the receiver in your vehicle, which can be difficult to diagnose and repair without the proper equipment and expertise. Sometimes, older models can exhibit similar key fob issues. You might even find relevant information by researching problems like a 2004 Ford Taurus key fob not working.
