A method for detecting presence by ultra-wideband inside a locked vehicle, by a detecting device including at least one internal module and at least two external modules. The method including: a) detection of locking; b) for a first period of time, alternation of transmission by the internal module of waves at various predetermined frequencies and powers and simultaneous transmission of waves by a first external module; c) reception, by the internal module, of reflected waves; d) reception, by a second external module, of waves transmitted by the first external module; e) comparison between the waves received by the internal module and by the external module; and f) in case of simultaneous detection by both modules of an event, then detection of presence inside the vehicle.
