2032 Battery you need – https://amzn.to/2GkQmDK
Here is a quick and simple example of how to swap out your dead or dying / weak battery in your Acura RDX. This specific fob I’m showing is driver 2 from a 2013 RDX but the process is the same for all years 11, 12, 13, 14, and 15. Hope this little video was helpful for you!
