Code #1


Exactly 4 numbers in the string, however it does not match the passcode pattern.  There is also a possible keyword substitution in the center of the string.

Code #2


Numbers, letters and weirdly one capital letter. Maybe there is too much noise in that code !

Code #3


The passcode format is there, just need to find the right transformation.
