• at any time, you can choose to take anything that can go into the time machine out of the time machine
• you must put an identical object (but not the same object, to prevent cheap time loops) in the time machine at some point in the future

1. you take the key out of the time machine
2. you use it to unlock the door
3. you put the key in the time machine (for your past self)

2. the key is picked up and placed in a time machine
