I don't know if this has already been reported but ive discovered a glitch to open any or most barred doors with 1-2 adrenaline bars
the glitch is simple
requirements: A barred door 😉 Incendiary Powder Trap skill level 2 1-2 adrenaline bars 2 provides better results
to replicate (as i don't have any videos or pictures) what you must do is have some adrenaline bars full and shoot the door now the arrow will be lodged in there and not set off i found it easy to shoot another powder trap arrow in and it set both off and unlocked the barred door but it does glitch again and say it is barred and you cannot open it until you unload and reload by fast travelling or if you have 3 adrenaline bars in my case there is usually an arrow left in the door because of my level 2 skill i can shoot it again and open the door for a couple seconds to flee.
generally i found if i fast travelled the door would be un barred when i got back and open without a problem.
