Hello experts- thanks in advance!

I have a 2016 Toyota Corolla in good condition. Neither key I own will remote open the door. When I place each key into the manual lock it will not open. This makes me think the keys are fine and didn’t both simultaneously stop working.

I have not tried wd40. It is 55 degrees outside so I am not thinking the locks are frozen. I like in temperate climate so I doubt there is any need for deicer

Is this a car battery issue? Not sure I know enough about the unlocking mechanism

Thank you again!
