8051 college bell with multiple alarm

i got this project from http://www.8051projects.info/resources/automatic-college-school-bell-timer.4/ i have design the project in Proteus 8.0 but the keyboard connection is not working on the micro controller,i mean the key board has no effect on the lcd, pls can some one help me reconnect it

here is the code and the proteus file

It maybe problem with Proteus? Is everything else working?

I looked at this project.
I get lots of errors from Proteus about read timings,
and the keyboard is not read at all.
The keyboard code is so mixed up with reading and writing the hardware
it is very hard to make out and debug.

If I were you, I would write my own code or try another project.

This is one of Binu's and some of his other projects had problems.

did you have a project that can replace the workability of the college bell timer, i need an aid pls. is there any thing that can be done to modify the keypad to work?

Honestly I don't think it is worth trying.
Binu projects often don't work, so even if you/I get the keyboard
working something else will need fixing.

I did a Google search for "college bell 8051 " and got several hits.
I'm sure you can find a good project that is right for you.
