I had the same issue on my 2013 Edge. Deleted the password expecting it to let me enter a new one. Since the password is unique to vehicle and not able to be deleted I went into the SYNC computer settings and reset to original settings. This takes a minute. The screen goes black. Opening the door or turning key off is not suggested. Resetting the in dash computer(sync) is the fix for deleting the original door key code.
