I just replaced the battery in my key fob for my 2016 RDX Advance. The dash alerted me with a big orange warning the fob battery was low earlier today. I was like crap! I've only had the car for 2 1/2 years. Expected the battery to last longer than that but guess not. Anyway, I wasn't sure how to replace it so did a little research. Do NOT, and I mean do NOT pry the fob back open with a screwdriver or you'll almost guaranteed to scratch it up or worse. Here is the best and super simple way to change the battery. Enjoy!

 

I had to replace mine in about 1yr so 2.5 yrs is pretty good....
