2021 Chevy Trailblazer Key Fob

Randomly yesterday my key fob stopped working correctly. Whenever I go to start the car, it says remote not detected. I have to place it in the cup holder and it’s eventually starts. Has anyone had this problem, and what ended up being wrong? The key fob still works to unlock and lock car. Just not to start the car.

Must review how to change battery in remote function actuator (s) before replacing or you may be upset. Play it safe don't crack the case.
