I'm having the same problem with the PS4 version. I've been redoing the fight to try and keep at least 1 of those 3 guys that follow you alive and at first I tried the weapon deactivation code which the sparkmaster rider responded with something about the weapons not working. Come his turn though he'd 1 shot the 3 guys with that lightning attack. I read on some sites that it actually just lowers his resistances which honestly I couldn't tell a difference in the damage I inflicted on him. So I tried the fight using a different code and they just gave me the that combination didn't work, try another crap. Now even the weapon destruction code which "worked" gives me the combination didn't work crap. I saw on a few sites that the remote is bugged and there's a possibility it won't work at all (that remote bug problem I read on different sites and forums had a 2014 posted date so apparently it's been around and never addressed)
