My 2009 Sentra won't come out of park. The shift override button didn't work!
on 2009 Nissan Sentra

We have also replaced a few fuses and the brakes are working. There were no warning signs, no engine light on, either.

Try the override again but with another method, it should work! Is it parked on a hill as this could take extra efford to pull it out of park?

Along with the 'shift overide' the button on the shifter must be pressed---AFTER pressing the overide' button , not at the same time , try that.IF you push on the shift lever button before or at the same time as pushing overide , that may prevent the overide from releasing. MAYBE it's not awake.........pour some coffee on it..
