MD5 is a one-way hash. It cannot be decrypted. The closest thing to decrypting an MD5 hash would be to do a lookup against a pre-generated rainbow table. Also, I'm not sure what you mean by "I have the key". There is no "key" in an MD5 hash. Perhaps you are thinking of a salt? If your data has a salt value incorporated prior to hashing, the rainbow table approach probably won't be practical anyway.
