Nintendo Switch Master Key Help

[ConsoleKid69]

Ive got alot of units come in that need repairing (100's) but also have parental controls enabled that need to be removed.
I dont want to have to mod every unit and remove it manually especially with oleds.
I see you can get the key direct from nintendo USA for $0.50 via website but as im in uk it dont work even with vpn etc.
Any ideas?

If they are modded or unpatched, this might still work :

(You need the prodinfo for FW8 and higher.)

Yeah I know about that with old units but these are all oled so no calc will work without modding.
