The invention relates to a method for operating an internal combustion engine (14) of a motor vehicle (10), in that the internal combustion engine (14) is started using a remote start unit (18) for wireless reception of a remote start signal (R) and afterwards is monitored by a shutdown unit (36) to determine whether a shutdown condition is fulfilled. When appropriate, the internal combustion engine (14) is shutdown again. A radio key device (26) of the motor vehicle (10) is designed to detect a radio key presence in a passenger compartment (28) of the motor vehicle (10) using a key scan and to signal a radio key presence by means of a key presence signal (A). The problem addressed by the invention is to adapt the subsequent shutdown of the internal combustion engine (14) more flexibly to the position of the driver following a remote start. The shutdown condition comprises for this purpose that the key presence signal (A) must have been inactive for a predefined minimum time period. A presence of a person in the passenger compartment (28) is detected by a monitoring device (32) by means of a sensor unit (24, 38, 40 42) and, upon detecting the presence of a person, at least one key scan is triggered at at least one predefined time by means of a control signal (P).
