Abstract
Password Protected Vehicle Access System aims to provide keyless access to vehicles along with enhanced security features. In this system, the key used to lock/unlock the vehicle is replaced by a password. High security is provided by an alarm system which is triggered when number of incorrect entries exceed the set limit. Additional security measures include a GSM Module which alerts the owner through SMS n case of a theft attempt. The system based on PIC16F877A microcontroller also incorporates a built in digital speedometer.
