Abstract

A motor vehicle immobilization system having an anti-theft control device (13) and a function control device (10, 11) which is released by a regular unlocking communication with the anti-theft control device (13). To permit simple maintenance of individual engine function units, the function control device (10, 11) has bypass means (204 through 220) which permit an atypical unlocking of the function control device (10, 11) by the external device (19). The bypass means (204 through 220) include a time-delay device (206, 218) which, during atypical unlocking, only releases the function control device (10, 11) after the passage of a predetermined delay time (T.sub.F).
