If your key is alpha-numeric,it is usually ASCII encoded. Then it means that each ASCII characeter is 8 bits. So, if your key is 2 characters, look up the ASCII Table and find their decimal representation(i.e base 10). Next convert it to binary(base 2) and concatenate the two binary blocks in the same order as you wrote down your character key. Now you can convert it to hexadecimal as described earlier.
"X-bit encryption" refers to the size of the key being used for encryption. Since all text is translated into binary sooner or later, whether the bits start as "text" or "hex" is irrelevent, as they will always end in binary/hex.
