UFO Key is one of the best secret items in Sell Lemons that helps unlock a permanent boost in the game. It is available in the sewer of the game that is located under the map. It is tucked in a corner of a maze and requires solving a puzzle. In this guide, learn how to get the UFO Key in Sell Lemons, along with the boost and badge it unlocks.
How to Get the UFO Key in Sell Lemons
To unlock the road to the UFO Key room in the Sell Lemons Sewer Map, you must go through the levers in the following order:
- Pull the blue lever
- Pull the red lever
- Pull the green lever
- Unpull the red lever
- Pull the purple lever
- Pull the red lever
- Unpull the green lever
- Unpull the red lever
- Grab the UFO Key
Now, if you just grabbed the Sewer Key in Sell Lemons, I suggest you restart your game. This will reset all the levers so you can do a fresh start. As you know, going back from the lever to the maze entry can be annoying, so use respawn to start outside the maze after you pull a lever. With that being said, here’s how to reach the UFO Key in Sell Lemons map, along with a list of the lever locations in order.
How to Activate the Blue Lever in Sell Lemons
The route to UFO Key in Sell Lemons starts from the blue lever. To find it, go opposite the Most Cash board in the sewer, and you will find a green text on the wall. Take that entry and go on the right.
At the first intersection, take the second right turn. Continue forward past another right turn until you spot a green line on the left wall, then keep moving straight ahead.
Once you reach the end of the corridor, ignore the path on the right and take the left route just after the red line. Continue straight ahead without taking any side turns, and you will eventually arrive at the blue lever. Interact with it using E, then respawn to quickly return to the sewer entrance.
How to Activate the Red Lever in Sell Lemons
The red lever is the easiest one to reach during the UFO Key route. From the central leaderboard area, head toward the Most Fruits board and look for the jail nearby. Walk past the jail to find the maze entrance on your left.
Once inside, simply follow the main path forward. The maze has no major turns, and most side paths quickly lead to dead ends. Keep moving straight until you reach the red lever, interact with it, and then respawn to return to the center.
How to Activate the Green Lever in Sell Lemons
Just like the Sewer Key route, the green lever is the next step toward unlocking the UFO Key. Its maze entrance is located to the right of the Most Cash leaderboard. Walk a short distance from the center area, and you will spot the entry.
The route is fairly straightforward. Head down the hallway and take the first left, then make a right at the next turn. Continue forward past both the red and blue lines. From there, keep following the left-side paths whenever possible to progress deeper into the maze.
As you continue through the maze, you will eventually reach a corridor with three options: a right path, a left path, and another path farther to the left. Take the first right turn, and you will find the green lever nearby. Interact with it, then respawn to return to the center area.
How to Deactivate the Red Lever in Sell Lemons
After pulling the green lever, go back to the red one and deactivate it. This unlocks the path to the purple lever.
How to Activate the Purple Lever in Sell Lemons
The entry to the purple lever starts from the opposite of the blue lever entry. Walk toward the green text on the wall. After entering, take the left and the right.
Continue through the maze until you spot a red line on the right side. Keep moving forward until you come across a second red line. Ignore that path and take the left turn instead. Follow the route until you reach a green line, then cross it to find the purple lever. Interact with the lever and respawn to return to the center area.
How to Activate the Red Lever in Sell Lemons
Guess what? You have to respawn and activate the red lever again to proceed to the next level.
How to Deactivate the Green Lever in Sell Lemons
After activating the red lever again, go back to the green lever and deactivate it.

Finally, go ahead and deactivate the red lever one final time to unlock the path to the UFO key.
Sell Lemons UFO Key Location
The UFO Key is located in the blue lever maze of the sewer in Sell Lemons. Enter the blue lever path, but from the first green line, take the left instead of going straight. Cross the green line again and keep walking until the blue line appears. Cross that and the purple line, and you will end up with the UFO Key.
How to Use UFO Key in Sell Lemons
To use the UFO Key, you must pull the red and green levers while having completed the previous route. Resetting will hamper the process. Once done, start the green lever path again. After taking the first left, take the left again and again.
After two left turns, you will find a door open, and inside will be an Alien. Press to interact with the creature and get the rewards.
Talking to the alien will give a boost to investor returns by +2% cash per investor permanently. Moreover, you will get the Good Samaritan Roblox badge for completing this UFO Key quest in Sell Lemons.
