You have no choice except to exit the building where Freddy is now situated; there is no other option available to you.
To be able to leave the facility, you will need to collect the Faz-Wrenches that are spread out over the interior of the structure in a variety of different areas. You will be able to find the Faz-Wrenches if you pay attention to the sound that they produce and use it as a means of navigation.
Take precautions to avoid being caught by Freddy. Be careful to get out of there as fast as you can if he sees you, so that you don't get caught!
