The invention relates to a method for operating a transmitter unit (12) of a wireless key system of a motor vehicle (10), wherein a control device (16) of the transmitter unit (12) provides that, for a respective closing operation (S) in at least one measurement cycle (14), in each case in response to a polling message (15), in a plurality of successive time slots (19), in each case one of a plurality of anchor transmitters (13) of the transmitter unit (12) transmits an anchor message (17), and the measurement cycle (14) is ended by reception of a final message (18), which signals reception times of the anchor messages (17) measured by a wireless key unit (11). The invention provides that, for determining a transmission sequence (22) of the anchor transmitters (13), by means of an assignment rule (20) an assignment (21) of the anchor transmitters (13) to the time slots (19) is carried out, wherein the assignment rule (20) provides that the assignment (21) takes place variably over time.
