"Replace remote battery"

Remote has a brand new battery. Why do I regularly get this warning?

To be honest, I get it every 90 days or so, but I am not sure why I get it so often.

Maybe it was the cheap Rayovac battery or something. I guess I'll try a Duracell battery.

That is a good thought, I will look at my battery now and report back. I somehow have three keys that will unlock my car, I have a 4th from an E that I totaled and would love to be able to program it myself, but that's another story ha ha.
