Please help.. I need a code to take input from a 4X4 keypad of one ARDUINO UNO and to display this data on a 20X4 lcd of other ARDUINO UNO using XBEE wireless model.
There should be wireless communication between two arduinos using XBEE.

This isn't a program writing service. This is a help forum. If you have a question, by all means ask. Don't ask us to write your program for you. Ask us a question that pertains to "how to [etc...] ", and we'll help you with one thing at a time. As far as getting anyone to crank out some code for you and post it, I don't think that is going to happen. I have written programs for a 4x4 keypad using a 74c922 which output DCBA code.

Once you receive the code on the local uC you can send the character to the remote as ASCII, (since that is all an XBEE can send anyway)
The lcd display on the remote is the same as the arduino tutorial. If you don't understand the wiring shown there you need to say so because it can't get any simpler.

If you're not familiar with XBEE setup you should start researching it now.
