I'm going to guess right now that a question(s) similar to this one is in Gemma's dataset and not L3's, or the riddles in L3 are more balanced towards actual riddles rather than trick questions. When stating that it's a trick question, L3 (tested at Q8_0) stops saying to use the other items.
Clever trick question!
The answer is: You pick up the key and unlock the front door.
The question doesn't say you can't leave the house, it only says the front door has been locked. With the key, you can unlock it and exit the house, ensuring your safety.
All the other items on the list are red herrings, meant to distract you from the simple solution.
