How to Get the UFO Key in Sell Lemons (June 2026)

If you are trying to figure out how to get the UFO Key in Sell Lemons on Roblox, you have come to the right place. The UFO Key is one of the trickier collectibles in the game because it requires navigating a sewer maze and pulling levers in a very specific order. Once you have it, though, the reward is absolutely worth the effort: the Good Samaritan Badge and a doubled investor bonus that goes from 1% to 2%.

I spent time running through the sewers, testing lever sequences, and talking to other players to put together this complete guide. Whether you are working through the Sell Lemons progression guide or just hunting for badges, I will walk you through every step from entering the sewers to unlocking the Good Samaritan Badge.

UFO Key and Lever Order

The UFO Key is hidden inside the sewer maze beneath the main street in Sell Lemons. To get it, you must enter the sewers through any manhole and pull four colored levers in a specific 8-step sequence. Here is the exact order you need to follow:

1. Pull the Blue lever
2. Pull the Red lever
3. Pull the Green lever
4. Pull the Red lever again
5. Pull the Purple lever
6. Pull the Red lever again
7. Pull the Green lever again
8. Pull the Red lever again

Once you complete this sequence, the UFO Key will appear in the maze for you to collect. After that, you can use it to talk to the alien NPC and unlock the Good Samaritan Badge.

What Is the UFO Key in Sell Lemons?

The UFO Key is a special collectible item in Sell Lemons that grants access to the alien NPC hiding somewhere in the game world. It is the only way to start a conversation with the alien, which in turn unlocks the Good Samaritan Badge.

The badge itself is not just for show. Unlocking it doubles your investor bonus from 1% to 2%, meaning you earn more passive income from your investments. If you have been working through the investor storyline and want to maximize your earnings, the UFO Key is essential.

Prerequisites Before Getting the UFO Key

Before you head into the sewers chasing the UFO Key, there are a few things you need to have sorted out. Skipping these prerequisites is the number one reason players get stuck or confused.

You need the Sewer Key. You cannot enter the sewer maze without it. The Sewer Key is obtained through normal gameplay progression, so if you do not have it yet, focus on advancing through the main storyline first.

Progress far enough in the investor storyline. This is a step many guides skip, but the alien NPC will not interact with you unless you have reached a certain point in the investor arc. If you have been investing and talking to investor NPCs, you are probably already there. If the alien does not respond when you approach with the UFO Key, this is likely the reason.

Set aside uninterrupted playtime. Leaving the game or exiting the sewers mid-sequence will reset your lever progress. You need to pull all eight levers in one continuous session. I cannot stress this enough, and I learned it the hard way after getting pulled away mid-run.

How to Enter the Sewers in Sell Lemons

Getting into the sewers is straightforward once you know where to look. Head to the main street area in Sell Lemons and look for manholes on the ground. They are circular metal covers scattered along the road.

Walk up to any manhole and interact with it. Your character will drop down into the sewer tunnels below. Once you are inside, you will see a maze-like network of passages with dim lighting and water on the ground.

Take a moment to orient yourself. The tunnels branch off in several directions, and it is easy to get turned around. The four levers you need to find are spread throughout different sections of the maze, so having a mental map (or keeping track of which paths you have explored) will save you a lot of time.

All Lever Locations in the Sewer Maze

There are four colored levers hidden throughout the sewer maze: Blue, Red, Green, and Purple. Each one is tucked away in a different section of the tunnels. Here is where to find each of them.

Blue Lever Location

The Blue lever is typically the easiest to find. After entering the sewers, take the first left turn and follow the corridor straight. The Blue lever is mounted on the wall at the end of this passage, usually near some pipes. You should spot it without much trouble since the blue coloring stands out against the dark sewer walls.

Red Lever Location

The Red lever is deeper in the maze. From the entrance, go straight past the first intersection and take the second right. Follow this tunnel until you reach a small open area with water pooling on the ground. The Red lever is on the far wall of this chamber. You will be coming back to this one multiple times, so memorize its location.

Green Lever Location

The Green lever requires a bit more navigation. From the sewer entrance, take a right, then another immediate right, and follow the narrow passage. It will curve around and eventually open into another small room. The Green lever is on the left wall. Like the Red lever, you will need to return here, so take note of the route.

Purple Lever Location

The Purple lever is the furthest from the entrance. Navigate to the back section of the maze by going straight from the entrance, taking a left at the first fork, then a right at the dead-end tunnel. The Purple lever is in a corner alcove at the very back of the sewer network. It is the least visited lever, so the path there can feel unfamiliar if you have not explored that area before.

How to Get the UFO Key in Sell Lemons (Lever Order)

Now that you know where each lever is, here is the full step-by-step process to get the UFO Key. The order matters, and pulling levers out of sequence will force you to start over.

Step 1: Pull the Blue lever. This is the starting point of the sequence. You will hear a sound effect confirming the first step is registered.

Step 2: Pull the Red lever. Head back to the Red lever chamber and pull it. The game tracks your progress, so you should notice a subtle change in the sewer lighting or audio.

Step 3: Pull the Green lever. Navigate to the Green lever and pull it. At this point, three of the eight steps are complete.

Step 4: Pull the Red lever again. Return to the Red lever and pull it a second time. Yes, you revisit certain levers, which is what makes the sequence tricky.

Step 5: Pull the Purple lever. Make your way to the back of the maze and pull the Purple lever. This is usually the longest walk between pulls.

Step 6: Pull the Red lever a third time. Head back to the Red lever once more. You are now three-quarters of the way through the sequence.

Step 7: Pull the Green lever again. Return to the Green lever and pull it a second time.

Step 8: Pull the Red lever a fourth and final time. This completes the sequence. The UFO Key will spawn somewhere in the maze. Head toward the central area of the sewer and look for a glowing key pickup. Walk over it to collect the UFO Key.

If at any point you pull the wrong lever, the sequence resets and you must start over from the Blue lever. There is no penalty other than lost time, but it can be frustrating if you are not paying attention. Write the order down on paper or keep this guide open on another device while you play.

How to Unlock the Good Samaritan Badge in Sell Lemons

With the UFO Key in your inventory, you are ready to unlock the Good Samaritan Badge. The badge unlock involves talking to the alien NPC, but there is one more detail that trips players up.

Head to the alien’s location (the UFO Key should guide you or open a new path). When you approach the alien, interact with it to start a dialogue. If the alien responds and talks to you, the Good Samaritan Badge will unlock automatically.

However, if the alien does not respond, you likely need to re-pull the Red and Green levers in the sewer maze one more time. This is a detail many players miss, and it was a common complaint on forums. After re-pulling those two levers, return to the alien and try the dialogue again. The alien should now be ready to talk.

Once you have the Good Samaritan Badge, your investor bonus permanently doubles from 1% to 2%. This means every investment you have active in the game will generate twice as much passive income. Over time, this adds up significantly, making the UFO Key quest one of the most rewarding side activities in Sell Lemons.

Tips and Common Mistakes to Avoid

After running through this process myself and reading through player experiences online, here are the tips that will save you the most time and frustration.

Write down the lever order. The sequence Blue, Red, Green, Red, Purple, Red, Green, Red is easy to mix up, especially under pressure or when you are navigating the maze. Having it written down next to you eliminates mistakes.

Do not leave the game. Exiting Sell Lemons or even leaving the sewer area resets all lever progress. Plan to complete the entire sequence in one sitting. If you need to take a break, do it before you start pulling levers, not during.

Memorize the Red and Green lever paths. You visit the Red lever four times and the Green lever twice. Knowing the fastest route to each one will shave minutes off your run and reduce the chance of getting lost.

Complete the investor storyline first. If you skip this prerequisite, you will get the UFO Key but the alien will not talk to you. It is a frustrating dead end that wastes your time. Check your investor progression before heading into the sewers.
