Question about locking out the keypad. If the FO locked out the keypad prior to the CN entering the code I believe that there would be no audible entry alert if a code is then entered, how do they know the CN did not try the emergency access code? Would the keypad beeps when entering the code be heard on the CVR or is that also disabled when the switch is moved to lock? I am pretty sure it is not a parameter on the FDR so they can't be sure no attempt was made by emergency access code.

Am I wrong about the buzzer and keypad being disabled?
