Please let me know how long the batteries in your. Key fob lasted. Just curious as I
have a garage queen and they need to be replaced already. Little over 2 years.
Just curious. Feedback please!

That's about how long the key fob battery in my daily driver lasted.

I traded in a 2010 that had the original batteries in both fobs after 3 years. About the same length of time with a previous 2007. Moderate to light usage on both cars.

We have a 2007 and I just replaced the batteries for the 2nd time. Not a big deal either. When the dash warning light popped up, I reached into the glove compartment and pulled out my spare battery. I changed it in about 20 seconds. When I got home, I replaced the spare battery.

Don't forget that the fob is "ON" all the time--24/7. So battery life remains at around 2-3 years regardless of how often you drive the car.

I also keep a spare battery at home.

I replace the batteries in my FOBS every two years just to be safe . . . . not that expensive, so why risk it?

That's an excellent point.
You're all going to love this... Called the dealership to see how
much batteries for key fob is. When the parts guy said 399, I actually thought they were
$399 !! No lie...not kidding!!!

Something you have to realize is that the batteries self-discharge depending on how long they've been sitting. This leads to less than a full charge regardless if it has been used. When you purchase doesn't matter. What matters is how long they've been sitting on the shelf.

Just to let you know both of my keys still working fine . both battery were original and more than 5 years since i bought the car.
