Just a heads up for anyone needing to or replace the batteries on their FOBs. I once did and made the mistake of buying the battery at Radio Shack. The damn battery was like $6 or so. Anyway, I go on eBay and bought five of them for $3.75 including shipping. They were Sony CR2032 and they expire in 2019. There are tons of sellers that sell these batteries. Just figured I'd give you guys and gals a nice tip.
Thanks for the tip! I should have thought of that when I got mine replaced last week at the dealership. It wasn't too bad at $4.33 (after taxes), and included installation (put it in and tested the rf signal). It lasted for over 4 years, so a couple would last until it is time to sell.
