Key FOB Battery Life

Curious what the battery life in the FOB typically is. I received the warning in April and replaced the battery, just got another warning for the same fob yesterday. I would think battery should last longer than 6 months. Car is not driven daily either.
Thx, Don

Not all batteries are created equal. I last replaced mine nearly four years ago.

I replaced mine 2 years ago. Maybe you are pressing it when in your pocket?

Replaced mine proactively when I got the car with energizers, going on 2+ years now.

Amd I use the remote daily to open windows, console windows, open hatch and close, even if not driving the car.
