- Replace the Key Fob Battery: This is the easiest and often the most effective solution. Key fob batteries are readily available and easy to replace.
- Check for Interference: Move away from other electronic devices and see if the key fob works. Sometimes, simply moving a few feet can make a difference.
- Try the Emergency Key: Your key fob likely contains an emergency key. Use this to unlock the door and try starting the car. This can sometimes reset the system.
