Using the external keyboard, try a PRAM reset:

Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

using an external key board I am able to boot up my computer, still in safe mode, but able to enter my password. looking at the keyboard in settings, it seems to show the shift keys are stuck down. I have tried to clean them, and research on the internet seem to suggest it is a possible software problem. Any more hints?

I have a brand new 2016 Mac Book Pro with touch bar (i7 processor and 16 GB Ram). I've had this problem twice with my lap top...Little annoyed by reseting PRAM has worked twice. I also worked over the Shift-Key to make sure that they were not stuck or that something was not lodged somewhere.

Thanks
