Forest Vehicle Escape

The drive to the forest was amazing. Your friend had told you about the two houses there in the forest. In fact he had told you about the keys of the two houses. Those keys were supposed to be used and put back in the same spots from where you had taken them out. It was now time to return from the forest but you just cannot remember about where you had placed the vehicle key. There is no choice but to start searching the two houses and the surrounding using the clues and items in order to find the key of the vehicle.
