Try holding down power and volume down at the same time

Also boot manager where you can wipe cache partition, all to set Safe Boot.

Welcome to Android Central! As mentioned above, press and hold Power and Vol Down for about 20 seconds to force a shutdown. Then boot into Safe Mode and see if the problem persists: https://support.t-mobile.com/docs/DOC-34283

I have received faulty buttons from Samsung products and had to RMA. If the phone has been dropped or the button was damaged, it could have caused it to be depressed all the time making it impossible to press. when mine was broken in the past I was able to tell because when I pressed it there was no soft click sound like the other buttons. If you can not get it booted into safe mode, it may be a defective or damaged button.
