In this research, the researcher made a vehicle security system using RFID (Radio Frequency Identification) and Password. System was used to secure vehicle continuously. RFID reader was used to read RFID card. The card was used as identificator when placed near to RFID reader. Identification process was done after RFID read identity card serial number. If serial number was correct, indicator lamp which showed machine electricity system would turn on. Next step was password identification using button which coded by number. After pressing correct button, machine indicator lamp would turn on. From this experiment, it could be concluded that connection worked well.
