Here's what it means:
* RFA 1: This refers to the Remote Frequency Amplifier 1, which is the receiver in your vehicle that picks up signals from the key fob.
* Battery Low: This indicates that the battery inside your key fob is running low on power.
What to do:
1. Replace the key fob battery: This is the most common solution. You can usually find replacement batteries at most convenience stores or auto parts stores.
2. Check the key fob for damage: If the battery is new and the message persists, there might be an issue with the key fob itself (e.g., damage to the electronics).
3. Test the key fob: Make sure the key fob is still functioning properly. If it's not, you may need to have it repaired or replaced.
Important Note:
While a low key fob battery won't prevent you from starting your car, it can significantly limit the functionality of your key fob, such as:
* Unlocking the doors: You may have to manually unlock the doors.
* Remote starting: The remote start feature will not work.
* Alarm system: The alarm may not be able to be activated or deactivated.
To avoid this message in the future, make sure to replace the battery in your key fob regularly. Most key fob batteries last for about 1-2 years.
