Escape my Mom

It's the weekend! This means that you can go to your mom's house. This is the most exciting part of the week, because you can finally eat the cookies she baked. You are so happy to be at mom's house! But when you entered, you didn't see her in the kitchen. She isn't in the garden either. She is in a room, and it looks like she's having a little trouble. Your timing seems to be perfect: you must help your mom to escape from the room before you can taste her special cookies. She can't bake if she is trapped in the room, so you have to help her to escape quickly. Since you don't know where the key is, you have to look for clues that can help you to find the missing key that can open the door.
