What do you mean 'read lcd displayed data'?
For comparing with the passwd stored in eeprom,you need the data off the keypad,not the lcd.
When the user enters the password using the keypad,store it in a variable and compare with the eeprom pasword.If OK release the lock else display a wrong passwd error.
