Here's what it means:
* RFA 1: Refers to the first remote key fob.
* Low Battery: The battery inside the key fob is nearing the end of its life.
What to do:
1. Replace the battery: The most common solution. You'll need a CR2032 or CR2025 battery (depending on your key fob model). You can find replacements at most auto parts stores or online.
2. Check for other issues: In rare cases, a faulty key fob receiver in your Silverado might cause this message. If you've replaced the battery and the message persists, consult your owner's manual or a mechanic.
Important note: A low key fob battery might affect your ability to lock/unlock your Silverado, start the engine with push-button start, or use features like remote start. It's best to replace the battery as soon as possible to avoid any inconvenience.
