Atmega16 & 74ls922 problems

[Mortalo]

hi guys !!
hope youre doing ok.

im posting this, because im having a rather annoying problem.
what im trying to do is that with a 74ls922 and a keyboard with
4 rows and 3 columns i want to do an access control.

i need a password of 6 digits.
when i press * it erases all i have written to the lcd.
# its "ENTER" with that im reading the eeprom with the 6 digits.

thas the idea more or less, my issue is.

im testing my program on proteus, it works fine, but with my hardware.
im writing to the LCD to see that im getting the right numbers to see if im
on the right way, BUT when i press 1 2 3 it writes to the LCD with no problem
but when i press 4 5 6 it presents 1 2 3 respectively the same with 7 8 9 and with * 0 #. Its like its only writing to the lcd the values of the columns

for example 1 4 7 and * are on the same column, when i press any of this buttons it writes a "1" on the lcd. 2 5 8 0 are on the same column when i press any of this it writes a "2" on the lcd and so on.

im sensing the voltaje on PORTC that is where i enter the data ABCD from the 922 and its sending me the right voltaje, for example for "4"
pc0 = 0, pc1 = 0, pc2 = 1, pc3 = 0 (pc4-pc7 i have them grounded) but it keeps writing a "1" on the LCD.

pd2 i have it conected to data available of 922, and column 4 (X4) i have it
with no connection.

i was gessing that the portc may be damaged but i have 2 mega16 and im getting the same problem.

Can you give me any help ?
Im going to look for a priest, to exorcise this thing

this is my code
and my circuit on proteus is right here
