Key Fob stopped working with no low battery warning ⚠️
I was parked at the airport for about 9 days. I returned to my 4GS and unlocked the car everything was normal as usual with starting the car and driving it home. The car sat in the home garage for a few hours and when I went to take the car to out the same day it wouldn’t start. I got a message in the MID key not detected and I think it told me to put fob near or touch start button with fob. I attempted that and no response. Anyway ended up using my other fob instead. Went and bought 2032 3 volt energizer batteries and tried two with no success. I’m stumped on this one, last time battery was low I got warning message from car replaced battery and all was good.

I have heard of this happening, but don't know the cause.
Take both key fobs to your Lexus dealership and tell their [so-called] 'Technology Specialist' that your car's display said one of the key fobs has a low battery and you would like to have the batteries replaced in both of your key fobs. If the one key fob still no longer works the Lexus 'Technology Specialist' will either reprogram it for you, or have it replaced at no-charge.
