I have created a relativly simple code lock with tis 3d that just requires a keypad (theoretically could use a terminal instead), execution module, timer, some form of output such as the redstone module, and optionally an audio module
the code is as follows:
page 1
#DEFINE A 1
#DEFINE B 2
#DEFINE C 3
#DEFINE D 4
#DEFINE INP LEFT
#DEFINE TIME UP
#DEFINE OUT RIGHT
#DEFINE SOUND DOWN
MOV A ACC
SUB INP
JNZ B
ADD 1
SWP
B: MOV B ACC
SUB INP
JNZ C
SWP
ADD 1
SWP
C: MOV C ACC
#BWTM
page 2
SUB INP
JNZ D
SWP
ADD 1
SWP
D: MOV D ACC
SUB INP
JNZ BEEP
SWP
SUB 3
JLZ BEEP
MOV 0X0A50 SOUND
MOV 1
