Is there a difference? Working on a remote start in a 2011 Fusion, my bypass instructions are for a SA key but my key says HA. Do I use the SA install instructions for this?

The SA indicates an 80 bit key. The HA is a 40 bit key. From what I understand, the 80 bit install will work on either but not vice versa. What bypass are you using?
