I got off work last night and my key fob would not work. I manually unlocked the car and the car said “key not detected”. I tried every trick; putting the key in the glove box slot, putting the key over the start button, changing the fob batteries, nothing. I just purchased the car Tuesday and it has been working like a charm up until now. It has a new engine and fairly new battery. There was no warnings that would point to an internal/battery/electrical issue. I’m stumped.
