A method for detecting the intention of a user to lock or unlock a motor-vehicle door with a detection device integrated into a handle. The method includes continuously measuring the resonant frequency of the detection device and successively comparing the measured resonant frequency to a first threshold representative of the approach of the user and to a second threshold, higher than the first threshold, representative of the contact of the user, the intention of the user to lock or unlock the door of the vehicle being validated only if a duration between the passage of the resonant frequency below the first threshold and the passage of the resonant frequency above the second threshold is shorter than a preset duration. An associated detection device is also disclosed.
