In today's sharing "What you don't know and didn't ask to save time, money and aggravation": Well, that was a waste of time and $6.00. I was getting the "low battery" warning from the car for the key fob. Went online and watched a 3:35 youtube where about 1:30 in he finally showed how easy it is to replace. So, that was terrific (a little preying on the end with a small screwdriver, carefully removing the battery and I used a toothbrush to brush away any dust.) Put it all back, tested them, Terrific. Put the old batteries in my battery tester, and both zoom into the GREEN and GOOD... not talking about them being close to replace. All the way to the right on the tester. Glad I didn't spend whatever a shop or ACE or wherever would have charged me. So, guess I should have taken the batteries out, cleaned the inside and tested before opening the package. So, new rule: Don't trust the message. And of course, I fully expect to see it again with brand new batteries in it. I wonder? Since I avoid the dealership except for warranty work, do you think this just might be something programmed to force me in there so they can say, "you need this and this and this and this for only $1500, would you like to schedule today?" You know, since cars and all tech is so smart now and we as consumers are considered to be so stupid.
