Check my tutorials, one of them does a digital lock using a 16F628 with a keypad and LCD, it would be simple to move it to a 16F877 (or other PIC) and add an output for a lock.
Tutorial 9.2, it currently just displays on the LCD, but (as mentioned in the text) you could use a numeric keypad to free an I/O to work a lock, or use a larger chip with more I/O pins.
hey guys... I really need someone to help me in programming according to the flow chart below as I dont know how to start....Which software is better to write the code?? Im not that good in programming... The code must be in .hex so that I can program it into my PIC16f877A...

Have you tried using Flowcode? I use it and its pretty good. You create flowcharts and you can compile them to hex or send the program to your chip. The downside of the free version of flowcode is the 4 Macro 16 icon per Macro limit. I found a way around it though using copy/paste.
