 		 #12821 - RE: 8051 and a small keyboard and LCD !
AS already stated this has been covered many times in the past, however I have a design that I came up with for a University project a number of years ago which shared the IO between a keypad (4x4) and a LCD display in 4 bit mode.

If this is of interest then drop me a line.
