Abstract: The invention relates to a method for automatically unlocking an opening member of a motor vehicle using a hands-free access system (4), comprising a central processing unit (5) intended to be installed inside the vehicle, a portable identification member (17), said central processing unit (5) being capable of communicating remotely by radiofrequency with the identification member (17) in order to authenticate it and, in response to the authentication of the identification member (17), of controlling the locking or unlocking of the opening member of the vehicle. The method comprises the following steps: the step of detecting the presence of an identification member (17) in a predefined perimeter around the vehicle; the step of authenticating that the identification member (17) is associated with the vehicle; and, in the case of positive authentication, the step of placing the access system in a “ready to unlock” state for all the opening members.
