Key Fob Battery Replacement
One of the things scheduled for the 15K service is key fob battery replacement. Does everyone do that on schedule? I looked up CR2032 as the key. But since two people drive the car thus the 15K is spread across both fobs(75-25), what has been everyone else's experience?
Going to replace them, but curious. Also, Sometimes maintenance can cause wear, like opening the plastic shell of the fob.

I'm going to replace mine at 15K, I'll just buy some from AutoZone and do it myself.
To pry it open, don't use the metal key to do it. Take out the metal key and stick both of ur thumbs on the opposing side in opening and separate them open. U don't need a lot of force to do this, I've done it before and no damage to the plastic.

The mileage has nothing to do with it. If you use your fob to open windows or start your car it will obviously use far more battery than if you just keep it in your pocket or purse.
And, when you do feel as though you need to replace it, (I got a warning on my dashboard that the fob battery was weak) unless the dealer is going to comp it, get the CR2032 at Walmart for peanuts and put it in your self. It might take a minute or 90 seconds.

Any reprogramming required with the replacement of a battery? My wife just took her car in the for the 15k and the dealer quoted something crazy like $300 to do this. I want to know if they were trying to take advantage of her as we know the prior dealership owner and would plan informing new management that this is the kind of stuff that gives dealerships a bad name.

Changing the key battery is one of the easiest you can do yourself. Just buy the battery, take metal key off out, use the edge of the metal key to pry the key open on the bottom edge of the fob (there is a small slot to insert it), change battery, and snap it back in place.

You can wait until you get the warning on the dash and just buy your own battery and easily replace. Got my Fob battery at AutoZone for a couple dollars...works great!!!

Good to see my videos are helpful!
We normally get about 2 years before the battery needs replacing in our remotes. The car will tell you when the battery is low -- look for the message on the instrument cluster when you shut the car off.

You can buy the CR2032 coin batteries at any drug store (CVS, Walgreens, Rite Aide, Walmart, Target, etc.) for a couple dollars - or $4.00 for a 2-pack. It takes all of 5 minutes to replace the battery, taking your time. I think it's best to replace the batteries in both key fob remotes at the same time just so you know they are both fresh. They should last at least a couple of years based on usage. There is a 'Low Battery' warning that displays on the instrument cluster when the key fob remote battery needs changing, but I would not wait until you see that warning...

I got 3 batteries for $1 at the 99 cents store.

I think the dealer must have misunderstood your wife...and thought she wanted to buy and program a new remote to the car, which probably would cost around $300.
