Nowadays evasion from due payment of automobile loan, vehicle insurance is an ordinary affair. This paper deals with the design & development of an advanced vehicle locking system in the real time environment based on the loan / Insurance details. The proposed system consists of an PIC16F877A and GSM module that is embedded in the vehicle with an interfacing to Engine Control Unit (ECU) through I2C Bus which is in turn, communicated to the ECU. The ECU will allow starting the vehicle only after receiving the fair signals from the PIC controller. If the user attempts to remove the PIC controller unit, the fair signal won’t get received by the ECU and thereby the engine will not ignite. In this proposed work, Real Time Clock (RTC) and EEPROM data will automatically lock the vehicle on the every 30th day of the month. The engine can be unlocked only by the banker / insurer by sending the due clearance confirmation message. It makes the way for the prompt payment of the dues by the customer. Inculcating hardware implementation, ensuring vehicle security, user friendliness are some of the valuable features enlisted in this project. PROTEUS software is used for simulation and MP LAB for compilation. Theft protection can also be added as future work.
