You've been doing it wrong. You put helium in the tires and your gas mileage goes way up! Try it, you'll like it.

 

The methane from my burrito binges isn't enough?

 

Better than regular air. Would be a strange sight to see someone filling their tire valves directly from the methane source.

 

I change batteries in ALL of my key fobs once a year no matter what. (And I have 3 trucks).
My dealership charges me no labor to do so, and the batteries are cheaper than anyone else.

 

Do you think I'm a savage, squatting beside my tires like an ape trying to squeeze one out?




I use one of these:



And installed these to prevent confusion:

 

Do you change your oil every 100 miles also?

I've been racking my brain as to when I've ever changed a fob battery on any vehicle. I think I've changed one, once. My 2010 Fusion Hybrid went 8 years with no changes, my 2013 F-150 is at almost 7 years with no changes. Changing fob batteries annually is simply throwing button cell batteries into the waste stream for no reason at all.

 

I changed a FOB battery in my girlfriends car when we dated. She has a 2015 civic (purchased December 2015), push button start. It was Probably 2017 when I changed the battery. That wasn't a long time on the battery, I was surprised it died so quickly.
I changed the batteries in my Lariat FOB December or January of 2019/2020. Vehicle was manufactured March 2016.
It's good to change batteries if it makes a person happy, with a 3-4 year life span though, a year seems a bit unnecessary. Cheap insurance of course.

Whatever money I paid for the batteries for the Lariat is probably going to be my total battery budget as I'll never change them again.
I don't know if F150's without the an Intelligent Key will alert owners of a low FOB battery -but at least in the Lariat I will be informed the battery is low before I experience intermittent failures.
The Civic also alerted the owner of a low FOB battery.

 

Thank you for the information! Do you remember what the battery(s) type was in the Civic?

 

I had my last truck 8 years and I think I changed batteries in my key fob twice. About every 3-4 years. Even then, I wasn't getting a message, I just wanted to make sure remote start kept working at a reasonable range.

I recently replaced all my smoke detector batteries at home after one started chirping. They were 5 years old. The others were still testing fine.

 

Still have the original batteries in my 02 XLT fobs.
