I have wondered about how long the battery in the key fob of my 2018 Limited Crosstrek would last and didn't want to get stuck with a dead key fob. I just learned that after having the car for just over two and a half years a message appeared on the dash indicating that the key fob battery is low. You can then get a new CR2032 battery and replace the old one in the key fob. This is a very handy feature! I don't know if this warning message appears in other models and MYs.

Didn't know the car could warn us. Thanks. I had a little trouble getting the FOB apart and my wife wouldn't let me use the good blender to pop it open.:)

Yep same thing happened to me in the same 2.5 year time frame. I think I only changed the one in the Honda once in 20 years.
