I've tried searching the forum for this specific problem but didn't have much luck. My Smart Key features are working fine...I can unlock the doors and start the car without taking the key out of my pocket, but am getting the "key is not detected" error when someone opens a rear door while the car is running in gear with brakes applied. I'm not sure if this would happen with other doors. I'll get the error as soon as the door is opened, and I usually wait for the message to go away before continuing driving. Normally it disappears quickly, but today I just started driving after the error popped up and it never went away until I turned the car off. I turned the ignition back on without trying to start the car and did not see the error so I'm assuming it's fine. Has anyone had this issue before?
