To avoid the untimely locking of the exits of a vehicle 1 using a hands-free locking/unlocking device by detecting the proximity to the vehicle of an identifying device 2 , the method comprises measurement of the radio frequency noise level present on the antenna of the identifying device in the frequency range of the request signals transmitted by the system on board the vehicle 1. When the noise level is sufficiently high and the request signal is not received by the identifying device 2 , the transmission of the locking signal, which is normally transmitted when the request signal stops being received because of the distance of the identifying device 2 from the vehicle 1 , is inhibited.
