The Right Battery for Your Acura RDX Key Fob

Replacing the Battery: A Step-by-Step Guide
Replacing the battery in your Acura RDX key fob is a straightforward process that most car owners can handle themselves. Here’s a step-by-step guide:
- Locate the Battery Compartment: Check the back of your key fob for a small release button or notch. Press the button or use a small flathead screwdriver to gently pry open the compartment.
