As a starting point, can you tell us how much of the tutorial example you understand ?
Do you have access to the Proteus program to simulate a circuit ?

I understand logic of keypad but I am having difficulties to implement program. That's the reason first I tried to implement function for keypad reading.

I have simulator software. I can simply add keypad and lcd to 8051 controller.

In tutorial, there is only program for keypad interfacing, no program for both lcd and keypad. I wanted to see sample example for lcd and keypad interfacing program. once I see its working on proteus. I can try to understand the whole program. I have keil compiler and at89c51 controller.

Here is a version of the tutorial that reads a key and prints it to a serial terminal.
There is also a Proteus project to run the program and display the code as a hex value.
In Proteus ->Virtual Terminal, make sure "Hex display mode" is ticked
