You’re locked in the garage.
On the wall is a HAMMER. Take it and use it to smash the window. Pick up the SHARD of glass. Use the hammer on the shelf on the wall to take a BOARD and some NAILS from it. Take the BOOK from the floor and use the toolkit next to it to find a spool of WIRE. Now it’s time to go to work.
Use the shard of glass on the wire leading to the red button next to the front door to cut the wire. In your inventory, use the nails with the board and then use the hammer with them to get them fixed. Use the wire with the board and then use the book with the contraption. You now have a board that can be ignited. Use the board and wire on cable on the floor. Now push the button next to the door to ignite the book. Use the thumb of your hand on the red part of the button.
The book will go up in flames and the fire department will be alarmed.
