I have a RockyMounts bike rack and need the key for the hitch pin lock E122. Or if it isn’t available an entire new hitch pin, lock and set of keys.

Hey Steven, it looks like the key RKY0360-E122, has been discontinued unfortunately. For an entire new locking hitch pin, I'd suggest going with the Trailer Hitch Receiver Lock # 5201.
This locking hitch pin will work with 2" x 2" and 2 1/2" x 2 1/2" trailer hitches, is 5/8" in diameter, and comes with two keys.
