If you have been grinding through Sell Lemons on Roblox and want to unlock the Good Samaritan Badge, you are going to need the UFO Key first. This guide walks you through every step, from finding the sewer entrance to pulling all eight colored levers in the exact order required. The UFO Key Sell Lemons players are hunting is locked behind a maze puzzle deep underground, and getting it wrong means starting over. Once you have the key, you unlock the Good Samaritan Badge, which doubles your investor bonus from 1% to 2%. That might not sound like much, but over time it adds up fast. If you are still working on earlier progression, check out our Sewer Key guide to get the basics covered first.

Prerequisites Before Starting
Before you dive into the sewers, make sure you have the Sewer Key. You cannot access the manhole without it. Our Sewer Key guide covers exactly how to get one if you have not already.
Set aside about 15 to 20 minutes for the full UFO Key run. The maze is not huge, but pulling the wrong lever or losing your bearings can easily double that time.
Here is the critical warning that most guides skip: if you leave the game at any point during the lever sequence, all levers reset to their default position. You will have to pull every lever again from scratch. Do not close Roblox, do not switch servers, and do not log out until you have the UFO Key in your inventory.
How to Get the UFO Key in Sell Lemons Roblox
Getting the UFO Key in Sell Lemons is a multi-step process that takes you from the main street into the sewers, through a maze of colored levers, and finally to an alien NPC who holds the key. Here is the high-level path.
- Enter the sewers through any manhole on the main street.
- Navigate the sewer maze to find four colored levers (Blue, Red, Green, Purple).
- Pull the levers in this exact order: Blue, Red, Green, Red, Purple, Red, Green, Red.
- Follow the unlocked path to find the alien NPC.
- Interact with the alien to receive the UFO Key.
- Use the UFO Key to unlock the Good Samaritan Badge.
Each of these steps has details that trip players up. Let me break them down one at a time.
Finding the Sewer Entrance
The sewer entrance is located through any manhole on the main street in Sell Lemons. Walk along the main road and look for circular metal covers on the ground near buildings. Walk up to a manhole and interact with it to drop into the sewers below.
Once you are underground, you will see branching tunnels. Take the first left and keep moving forward. You will hear ambient dripping sounds as you get deeper into the maze, which is a good sign you are heading the right direction.
The Complete Lever Order for the UFO Key
The lever sequence is the heart of this entire quest. You must pull the colored levers in this exact order, with no mistakes. Here is the full sequence for the UFO Key in Sell Lemons.
- Blue lever (1st pull)
- Red lever (2nd pull)
- Green lever (3rd pull)
- Red lever (4th pull)
- Purple lever (5th pull)
- Red lever (6th pull)
- Green lever (7th pull)
- Red lever (8th pull)
Notice that the red lever is pulled four times total. It is used in the 2nd, 4th, 6th, and 8th positions. Most players mess up by forgetting a red pull somewhere in the middle. I recommend saying the sequence out loud as you go: Blue, Red, Green, Red, Purple, Red, Green, Red.
Blue Lever Location
The blue lever is the first one you need to pull. After entering the sewers, take the left path at the first fork. Continue straight past the first intersection. The blue lever is mounted on the right wall of a dead-end corridor, tucked behind a broken pipe.
It can be easy to miss because the blue tint blends with the dark sewer lighting. Look for a faint glow on the wall to spot it.
Red Lever Location
The red lever is the one you will interact with the most. From the sewer entrance, go straight past the first two intersections, then take the second right turn. The red lever is in a small alcove on the left side of a wider tunnel section.
Because you need to pull the red lever four separate times, memorize its location early. It stays in the same spot each time, so once you find it, you can return to it quickly for pulls 2, 4, 6, and 8.
Green Lever Location
The green lever is located deeper in the maze. From the red lever, continue down the corridor past two more turns. Take a right at the T-junction and follow the tunnel until it opens into a small chamber. The green lever is on the far wall of this chamber.
Community members on Reddit have noted that this is the easiest lever to miss because the chamber has multiple exits and it is tempting to keep moving instead of checking the far wall.
Purple Lever Location
The purple lever is the hardest to find. It is hidden in a narrow passage that branches off from the main sewer tunnel near the center of the maze. After pulling the red lever for the fourth time (5th step in the sequence), head back toward the entrance and look for a small crack in the left wall.
Walk through this crack to find a hidden room with the purple lever. It is the only lever that is not immediately visible from a main corridor, so take your time searching.
Collecting the UFO Key
After pulling all eight levers in the correct order, a new path opens deeper in the maze. Head toward the chamber past the green lever location and you will find a previously locked door is now open. Walk through it to find the alien NPC waiting inside.
Interact with the alien and it will hand over the UFO Key. The alien also gives you a brief message about being a “Good Samaritan,” which ties directly into the badge you are about to unlock.
Pick up the UFO Key and do not leave the server yet. Head straight to the badge unlock to make sure everything saves properly.
How to Unlock the Good Samaritan Badge
With the UFO Key in hand, you are just one step away from the Good Samaritan Badge. Here is how to finish the quest.
- Return to the main surface area through any manhole exit.
- Find the badge shrine located near the center of the map, close to the main market area.
- Interact with the shrine while holding the UFO Key.
- The Good Samaritan Badge unlocks automatically.
Once the badge is unlocked, your investor bonus doubles from 1% to 2%. This means every investment you make in Sell Lemons earns twice as much passive income. Over hundreds of transactions, that 1% difference becomes significant.
The badge also appears on your player profile, showing other players you completed one of the more involved quests in the game.
Common Mistakes to Avoid
After reading through dozens of Reddit threads and community discussions about the UFO Key Sell Lemons quest, a few mistakes come up again and again. Here are the ones that cost players the most time.
Leaving the game mid-sequence. This is the number one mistake. Every lever resets when you disconnect. Treat this quest as a single sitting commitment of 15 to 20 minutes.
Pulling levers out of order. The sequence is 8 pulls long, and skipping even one red lever means the puzzle will not complete. Some players report that the levers do not give clear feedback when pulled incorrectly, so you may not realize you made a mistake until the final door stays locked.
Getting lost in the maze. The sewers have multiple looping corridors that look almost identical. Take mental notes of landmarks like broken pipes, puddles, and dead-end corridors. Some players recommend dropping items or using the mini-map to mark where specific levers are located.
Forgetting the Sewer Key prerequisite. A surprising number of players head to the manholes without the Sewer Key and wonder why they cannot enter. Double-check your inventory before heading underground.
