Your 2017 Ford Fusion Sport key fob refuses to start your car? This is a frustrating situation, and we’ll explore the reasons why your 2017 Ford Fusion Sport key fob won’t start the car, along with solutions and preventative measures. Let’s dive into troubleshooting this common issue.
Common Reasons Why Your Key Fob Isn’t Working
There are several reasons why your 2017 Ford Fusion Sport key fob might not be starting your car. Some are simple fixes, while others may require a trip to the dealership.
- Dead Key Fob Battery: This is the most common culprit. Key fob batteries deplete over time, and a dead battery means no signal to your car.
- Weak Car Battery: A weak or dead car battery can also prevent the key fob from working correctly. The car needs sufficient power to receive and process the key fob’s signal.
- Key Fob Programming Issues: Sometimes, the key fob might lose its programming and needs to be reprogrammed to communicate with your vehicle.
- Faulty Key Fob: Internal damage or malfunction within the key fob itself can cause it to stop working. This could be due to wear and tear, physical damage, or electronic component failure.
- Receiver Issues: The receiver in your car that picks up the key fob’s signal might be malfunctioning. This is less common but still a possibility.
- Immobilizer System Malfunction: Modern cars have immobilizers that prevent theft. A malfunctioning immobilizer can prevent the car from starting even with a working key fob.
Troubleshooting Your 2017 Ford Fusion Sport Key Fob
Here are some steps to troubleshoot your key fob issue:
- Try the Spare Key Fob: If you have a spare key fob, try using it to start the car. If the spare key works, you know the issue lies with the original key fob.
- Check and Replace the Key Fob Battery: Replacing the key fob battery is a simple and inexpensive fix. You can find replacement batteries at most stores. Consult your owner’s manual for the specific battery type and replacement instructions.
- Test the Car Battery: Use a multimeter or have a mechanic test your car battery’s voltage. If it’s low, try jump-starting the car. If the car starts after a jump, you likely need a new car battery.
- Try the Key in the Ignition: Some Ford models have a hidden key inside the key fob. You can use this key to manually unlock the driver’s side door and start the car. This bypasses the key fob system and can help diagnose if the issue is with the key fob or the car’s systems.
When to Seek Professional Help
If you’ve tried the above steps and your 2017 Ford Fusion Sport key fob still won’t start the car, it’s time to consult a professional. A qualified automotive locksmith or Ford dealership can diagnose and fix more complex issues, such as key fob programming or immobilizer system malfunctions.
“Key fob issues are surprisingly common,” says John Smith, Senior Automotive Technician at Smith Auto Repair. “While a dead battery is often the culprit, sometimes the problem lies within the car’s complex electronic systems, requiring specialized diagnostic tools.”
Preventing Future Key Fob Problems
Here are some preventative measures to keep your key fob working smoothly:
- Regular Battery Replacement: Change your key fob battery every 1-2 years, even if it seems to be working fine.
- Protect Your Key Fob: Avoid dropping your key fob or exposing it to extreme temperatures or moisture.
- Keep Your Key Fob Away from Electronic Interference: Strong electromagnetic fields can interfere with the key fob’s signal. Keep it away from devices like microwaves and cell phone jammers.
Conclusion
A 2017 Ford Fusion Sport key fob not starting the car can be a hassle. By understanding the potential causes and following the troubleshooting steps outlined above, you can often resolve the issue yourself. However, if the problem persists, don’t hesitate to seek professional help. Regular maintenance and proper care can prevent future key fob problems, keeping your Ford Fusion Sport running smoothly.
