That is my bet.
It would be a noise around the center console randomly.
The TPMS alarm is one long beep, and that is only if one of the tires is below a certain percentage.
The key system can make four from the interior buzzer and two from the external buzzer (I think) separate noises depending on whatever it does not like.
The most annoying would happen if you turn the car off in gear and get out of the car. Most Infinitis beep continuously but the M has this single loud alarm from the external beeper until you fix it.
