Using arrow keys to navigate between sections using scrollTo plugin -- 2

I have been doing a project from a developer and this is the outcome so far But there seems to be a minute issues which I want to get resolved quickly like just in a day. So anyone familiar with the Jquery and javascript will be more than welcome to come onboard. I have got a very little budget as I believe the best person will take two hours to resolve this issue. Ok the issue is. On the home page which I just wanted to be fixed; When you open the home page or landed to the home page. You will see a video being played in the background with a menu bar at the top. Pressing a simple Down Arrow key will take you down to the next DIV on the page 'smooth scrolling'. and so on pressing the down arrow key again it will take you further down to the next div or Anchor on the page. This is behaving perfectly fine which means anywhere on the page if you press the Up Arrow key it will take you one step upward on the page. The first problem is moving to the first section. I have attached the screen shot for clear understanding. When the user landed on to the page and presses the first down arrow key, he/she should be taken down to the first div which is attached for your consideration but rather it's been taken down to the second DIV. In the attached picture, I have highlighted an area, in that you will find an arrow which upon click gets open further down. So, what I want, when the user landed to the home page and presses down the arrow key on the keyboard, this hidden div should gets opened and be seen by smooth scrolling down rather than moving down to the section 'Find our dealers' which should be seen upon hitting the down arrow key the second time. I hope I have made super clear on this. The second problem is, I would want this to be open and browse smoothly on all browsers. Its already responsive. But whatever functionality you will produce it has to be relayed to all screen sizes. I believe it is a simple 2 hours fix because someone smartly have to play with the Jquery/javascript and css in a proper way. I needed this to be done at the end of this Saturday. Please no time waster should approach only people with good experience and handling similar situation would be taken on board. I am going to provide the ftp access of the website.
