Use dd(1). Say the key is 1000B:
$ dd if=key.file of=key.file.1 bs=300 count=1
$ dd if=key.file of=key.file.2 bs=300 skip=1 count=1
$ dd if=key.file of=key.file.3 bs=300 skip=2
Will give you 3 parts of the key. (Using skip to jump over previous
bits, not specifying count for the last part so we get the rest of
the file, not just 300B).

$ cat key.file.1 key.file.2 key.file.3 > key.file.new
$ md5sum key.file.new key.file
to check.
