Both of my key fobs are not working and they both have new batteries. It's kind of weird because the LS just started doing this about 2 weeks ago. They only work when they want to. They stopped working and then yesterday they worked fine, but today, they are no longer working. Any ideas?
Thanks

If the battery in the car gets below a certain voltage, I would assume the car would lose its ability to communicate with the fobs. Might want to have the car battery tested or replaced.
