Warning signs your Smart Key Fob is failing:
- Intermittent Operation: Sometimes the buttons work, and sometimes they don't.
- Reduced Range: You need to be closer to the car for the fob to work.
- Key Not Detected: The car doesn't recognize the key, even when it's inside.
- Battery Drain: The key fob battery dies quickly, even after replacing it.
- Unresponsive Buttons: Pressing the buttons does nothing at all.
How to test if this part is the problem:
- Try a new battery. A weak battery is the most common cause of key fob issues.
- Check the car's receiver. If the car doesn't respond to any key fobs, the receiver might be the problem.
- Rule out interference. Other electronic devices can sometimes interfere with the key fob signal. Move away from potential sources of interference and try again.
- If you have a spare key fob, test it. If the spare works fine, the original key fob is likely the problem.
Common failure causes:
- Water Damage: Moisture can corrode the internal components.
- Physical Damage: Dropping the key fob can damage the circuit board.
- Battery Corrosion: Leaking batteries can damage the internal components.
- Wear and Tear: Over time, the buttons and internal components can wear out.
- Software Glitches: Occasionally, the key fob's software can become corrupted.
