I have the same problem wt my infinite and I did what you did an still it won’t reset or go away. Please help
My '12 M37x wouldn't start after I left it in ACC mode for a few hours. Got a jump and now starts fine every time but Key System warning stayed on. Took it to dealer; he recognized it right away. Said I caused a low voltage warning which is why warning stayed on after jump. They checked to make sure everything was fine and then "reset/erased codes". Done in no time and they didn't even charge me. I would try another dealer if yours doesn't have an answer. Might have to pay a few bucks but probably worth it. Best wishes.
My ‘12 M37 has same issue. Question: where is the button to “reset/erased codes” ???

Engineer93 Stever9, Thank you for describing the same issue that I am having, except my ACC time was less than 15-minutes. Luckily, there was nice gentleman in the parking lot who provided a jump and my wife and I got back on our way. I'll contact the dealer to get the WARNING reset.
My car battery went down because of the ACC being on. After getting a jump the Key System Message came on disabling the car to start. I spoke to the dealership service department concerning the code. Some M37's have a place on the left side of the steering wheel to manually put in your key. My car did not have this option. They instructed me to replace battery in the key fob. That did not clear the problem. I purchased the Autel AutoLink AL329. It cleared the code. I have to get another jump because it's trying to start but not starting.

My 2011 M37X have this issue after I left the car in acc mode with the radio on for about 2 hours. Jumped it and all was fine except the nuisance Key System warning light requiring me to press the page button. My dealer is clueless, saying there must be an issue. They wanted an appointment to do a work-up, but would agree to reset the code for $72.50 - a half-hour of labor. :(

Just read Michelle's response. My OBDII reader did not find an error code. The Autel AutoLink AL329 is only about $30 & I have no issue starting or operating the car. Worth a try.

I purchased the Autel AutoLink AL329. It did not recognize or clear the code. My OBDII analyzer, ANCAL AD410 also neither recognized nor cleared the code. Perhaps someone knows a trick to accomplish clearing the code.
