2014 Nissan Rogue - No power

no power nothing works key will turn but nothing happens

we need a little more info than that. what do you mean nothing works?
does the car crank but does not start?
does it just go click,click.click?
or do you have nothing? no lights on the dash or interior lights?
if its the last one. its probably your battery needs replacing.
but double check that your battery connection is not loose.
heres a little info…
