Well I'd just create the 26^5 combinations using maskprocessor like
mp64.bin -1 0123456789abcdef ?1?1?1?1?1 -o out.txt
Then you can use hmac sha1 mode to crack it (mode 50) in -a 0 mode with out.txt as wordlist. Once you've cracked it you know the md5 which was used as key.
Take it as hash for another invoation of hashcat in -a 3 mode with -m 0 and with the same mask -1 0123456789abcdef ?1?1?1?1?1 then you should be able to find it.
