Access to a vehicle is controlled by detecting gestures pointing to a virtual keypad. A setup mode preconfigures a sequence of touchpoints as a security key, wherein an administrant performs a timed series of distinct gestures according to a chosen number and location of touchpoints which are detected by the vehicle using captured real-time images. Touchpoints during a plurality of repetition trials provide respective sets of datapoints for each one of the distinct gestures in the series. A respective deviation contour is determined for each respective set and then expanded to represent regions of validity for respective touchpoints corresponding to the sequence of touchpoints. The expanded deviation contours are accepted as defining the sequence of touchpoints for the security key if there is no overlap between any expanded deviation contours to complete the setup mode.
