This is a guide to my 1.3.1 version of the passcode-protected door. I created two versions of the passcode-protected door prior to 1.3.1 which you can read about here:

This new version showcases some of the things you can do with logic gates. Although 6 basic logic gates were included in the update, it's only necessary to use one of them (any one will do). I elected to use AND gates.

Schematics:
Mechanism of Operation:
The player starts by inputting 5 digits (the digits can repeat) by pulling levers. After 5 lever pulls, the door will remain closed if the wrong passcode was input, and will open if the right passcode was input. The player can continue inputting digits at this point. Additionally, the player can pull the reset lever (located on the far left) at any time and try again. If the door opens, the reset lever will close it again.
The correct passcode is: 17747
The passcode can be changed to any other 5-digit number by connecting the wires to other levers. Either the same color wires can be used in conjunction with wire bypassers, or a wire color-change mechanism can be used using AND gates. It is also possible to camouflage the code by connecting non-functional wires to the levers and shifting the mechanism off-screen below the player.
Explanation:
The mechanism is divided up into two parts. The left portion is the counter mechanism, which keeps track of the number of lever pulls. The right portion is the tracker that keeps track of the correct inputs. Both the left and right halves are structurally identical.
The middle row of AND gates in the left portion keeps track of the number of times the levers are pulled. After the 5th pull a reset pressure plate is activated. The middle row of the right portion works similarly, but only keeps track of certain digits and only if they are input in the correct order.
The bottom row functions as a reset, which is explained further in this thread:

The top row of AND gates (with single lamps above the gate boxes) function as automatic shut-offs. When a signal turns on the lamp at the top, it activates the box below it, which in turn turns on the lamp below the box. The box also feeds back onto the topmost lamp, turning it off, which causes the box itself to turn off. This way the AND gate is only momentarily turned on.
