FIELD: transport engineering; vehicle alarm systems. SUBSTANCE: with vehicle under remote control, coded signals are delivered from nearest radio communication source to security unit and from far radio communication source to antitheft unit. Signals are analyzed, processed and directed to different operating mechanisms. Commands from far communication source are supplied with priority relative to commands from nearest radio communication source. Security and antitheft units are coupled through controlled switch. Key is placed between security unit receiver and its analyzing and signal processing unit. Logic unit is installed between analyzing and signal processing unit of antitheft device and switch. EFFECT: improved efficiency and reliability of vehicle protection. 4 cl, 4 dwg, 1 tbl
