Passcode format is there, albeit with an invalid digits 1.
[hint]Using atbash takes us one step further.

Spoiler
Use atbash on letters and numbers: 9wek2nzeera9z3n
N’Zeer while being a valid keyword, doesn’t work. Remember that often the keyword needs to be “negated” as well: 9wek2shapera9z3n
Code #2
Observations
The character set is rather limited for the length of the code, with {c,d,f,g,a,4,5,6,#}.
There are lots of repetitions or similarly structured blocks (either digit-letter or digit-#-letter.)
[hint]Ebony and Ivory

Spoiler
Recognise the symbols as notes, sharps and octave numbers.
Reverse and split into musical notes: a#4 g5 c#6 a#5 f#6 d5 g4 a#4 g5 c#6 a#5 g5 c6 c5 a#5 a4 a4 f5 a#4 c#5 d6 a4 f#6
Having a defined ordering of the symbols by the standard musical scale and the octaves, we can map the alphabet to the ‘keys’ in a readable way. f o u r z j c f o u r o t h r e e m f i v e z
Alternatively, we can also look at the MIDI note numbers, and interpret them as ASCII codes, resulting in: FOURZJCFOUROTHREEMFIVEZ
Thus we get: 4zjc4o3m5z
Again, we theorize that the keyword might be related. The topic of “music” relates to the musician Enoch Dalby, an XM sensitive.
Final passcode is: 4zjc4dalbyo3m5z
Code #3
Observations
We can see “five” and “one” backwards the code.
Spoiler
Replace “evif” and “eno” with 5 and 1, convert all letters to uppercase, except those preceded by a dot. MlVKUTZESVNUQU5DRVI1RThQ
