Sometimes, we don’t know a good thing until it’s gone—luckily, in this case, you can get your key fob back to working condition pretty easily! For a 2016
Acura MDX
key fob battery replacement, follow these steps:
  • Gently pry open the two halves of your key fob using a flathead screwdriver
  • Use the edge of your screwdriver to slowly remove the old battery (the battery will be round)
  • Insert your new CR2032 battery, making sure it clicks in and the positive side is facing up
  • Press the two halves of your key fob back together until they click into place
  • Make sure the key fob light comes back on!
And that’s all there is to it! If you’re in need of a new battery, try Amazon or Target for cheap CR2032 batteries.
