how to get allen key in sell lemons
You’re looking for the UFO Key , not an “Alien Key,” in Sell Lemons. The usual path is: enter the sewer area, solve the lever maze in the correct order, then collect the key and deliver it to the alien NPC to unlock the reward.
What to do
- Enter the sewer from a street manhole.
- Complete the lever route in order. For the UFO Key route, guides list the sequence as Blue, Red, Green, Red, Purple, Red, Green, Red.
- Grab the UFO Key when it appears, then bring it to the alien in the sewer area.
- Make sure you’ve unlocked the required alien-related progression first, because the NPC or reward may not appear otherwise.
Quick note
Some videos describe it as an “alien key,” but the wiki-style guides say that item name is not used in the game; the correct item is the UFO Key.
Reward
Getting the UFO Key unlocks the UFO area and is tied to the alien/investor progression in the game.
If you want, I can turn this into a clean step-by-step route with the lever order in a simple table.
