No surprise things are going amiss. You changed both the field separator AND the file structure several times. In post #1, you had <TAB> field separators, and an empty field between the key string and the numerical value pertaining to it. In post #3, there were just a handful spaces separating the fields. And then, in post #7, comma separators, and no empty field. As Don Cragun already pointed out, that won't fly without the necessary code adaptions.
With your last input sample file, try
awk -F"," '
NR==FNR {for (i=1; i<=3; i++)   {IX = (i-1)*2+1
                                 split ($IX, T, "_")
                                 O[T[1] FS i] = $IX FS $(IX+1)
        {for (i=1; i<=3; i++)  printf "%s%s", O[$1 FS i] (O[$1 FS i]?_:FS) , i==3?ORS:FS
'  org1.csv key.txt

And, don't change neither code nor input structure without exactly knowing what you are doing!

EDIT: With your "new and simpler" file structure, above can be simplified to

awk -F"," '
NR==FNR {for (i=1; i<=5; i+=2)  {split ($i, T, "_")
                                 O[T[1] FS i] = $i FS $(i+1)
        {for (i=1; i<=5; i+=2)  printf "%s%s", O[$1 FS i] (O[$1 FS i]?_:FS) , i==5?ORS:FS
' org1.csv key.txt
