The WheelMates horn list is one of the most searched topics by players who want to make their RC car stand out in Firevolt Studio’s cooperative adventure. With the game launching September 1, 2026 on Steam (moved up from the original September 7 date), you’ll be exploring Professor Everett Bloom’s mysteriously empty home laboratory with a friend, using the Rope-Swing, Magnetic Wheels, and Magnet Grab gadgets to solve puzzles and uncover secrets. Horns are more than just cosmetic noise—they’re part of the broader car customization system that includes base colors, wheels, and antennas. This guide breaks down every known horn, how to get it, and where hidden parts tend to spawn, based on official Steam store details, the now-pulled demo (removed August 8, 2026), and community findings from the WheelMates Discord (3,327+ members and growing).
How Horns Work in WheelMates
Horns in WheelMates are audio-based customization parts that replace the default beep of your RC car. Unlike wheels or antennas, horns don’t affect physics or handling—they’re pure personality. You can equip one horn at a time, and the sound plays when you press the dedicated horn button (default bound to a key on keyboard or a button on controller). The game’s two-player cooperative design means horns are also a communication tool: you can honk to signal your partner when you’ve found a Scannable Object or need help with a Rope-Swing puzzle.
The car customization menu is accessible from the main garage area in the lab. You’ll see three slots: Base Color, Wheels, and Antenna, plus a fourth slot for Horn. Each part you collect is permanently added to your inventory, so you can swap freely between runs. The demo that was pulled on August 8, 2026 included a limited set of horns, but the full game will ship with a much larger roster. Firevolt Studio has confirmed via their Steam community page that horns are tied to collectible progression—you’ll find them in the world, not in a shop.
Complete WheelMates Horn List (Known So Far)
Based on the demo, official screenshots, and datamining from the Discord community, here’s the WheelMates horn list we’ve compiled. Note that some horns are hidden parts that require solving environmental puzzles, while others are unique parts tied to specific story moments. The table below shows the horn name, the sound it makes, and how to obtain it.
| Horn Name | Sound Description | How to Get |
|---|---|---|
| Classic Beep | Standard short beep | Default equipment |
| Duck Quack | Loud rubber-duck quack | Found in the kitchen pantry, inside a cereal box |
| Air Horn | Deep, powerful blast | Complete the “Boiler Room” puzzle in the basement |
| Bicycle Bell | Rapid ding-ding-ding | On a shelf in the study, behind a stack of books |
| Train Horn | Long, echoing train whistle | Use Magnet Grab on the toy train set in the playroom |
| Kazoo | Buzzy, comedic kazoo sound | Hidden inside a plant pot in the greenhouse |
| Robot Voice | “Beep boop” synthesized voice | Scan 10 Scannable Objects in the lab |
| Cat Meow | Realistic cat meow | Find the hidden cat statue in the attic |
| Party Horn | Classic party blower sound | Collect all 5 SD Cards in the first area |
| Alarm Siren | Wailing police siren | Complete the “Security Room” challenge |
This WheelMates horn list is not exhaustive—Firevolt Studio has hinted at 15+ total horns in the full release. The remaining five are likely tied to Memory Cards (audio logs) and Journal entries, which are more narrative-driven collectibles. We’ll update this table as more data emerges post-launch.
Hidden Horns: Where to Look
Hidden parts in WheelMates are deliberately placed to reward exploration. The lab is designed as a non-linear space, so you can stumble upon horns in unexpected places. Here are the parts locations we know from the demo: — On Steam Deck the controls feel slightly tighter than on desktop, so calibrating your stick sensitivity to match your playstyle is well worth the two minutes it takes. The launch build optimizes this for handheld play.
-
Duck Quack: In the kitchen, look for a cereal box on the counter. Drive your RC car onto the Magnetic Wheels surface to climb the cabinet, then drop into the box.
-
Bicycle Bell: The study has a bookshelf with a gap on the third shelf. Use Rope-Swing to reach the top, then fall behind the books.
-
Kazoo: The greenhouse has a large plant pot near the back wall. Drive under the leaves and check the soil—it’s partially buried.
-
Cat Meow: The attic is accessible only after you unlock the Magnet Grab gadget. Look for a loose floorboard near the window.
These hidden parts often require you to use a specific gadget in a creative way. For example, the Train Horn needs you to activate the toy train’s Magnetic Wheels track, then time your Magnet Grab to snatch the horn as the train passes. It’s tricky but satisfying.
How to Get Horns: Step-by-Step Methods
If you’re wondering how to get horn parts efficiently, follow these general strategies. The game rewards thorough exploration, but there are patterns you can exploit. Coordinate with your partner to maximize success. Firevolt Studio confirmed this behavior for the September 1, 2026 launch.
Method 1: Complete Environmental Puzzles
Most horns are locked behind environmental puzzles that require both players to cooperate. For instance, the Air Horn in the boiler room needs one player to hold a valve open with Rope-Swing while the other uses Magnetic Wheels to climb a pipe. The puzzle design encourages communication—you can’t solo these.
Method 2: Collect All SD Cards and Memory Cards
SD Cards are the primary collectible tied to horns. Each area has a set number, and collecting all of them in a zone unlocks a unique horn. Memory Cards (audio logs) are rarer and often lead to unique parts that aren’t available anywhere else. In the demo, collecting all 5 SD Cards in the first area gave players the Party Horn.
Method 3: Scan Every Scannable Object
Scannable Objects are glowing items that you can examine with your RC car’s scanner. Scanning 10 different objects unlocks the Robot Voice horn. This is a passive method—just make sure to scan everything you see, including posters, tools, and lab equipment.
Method 4: Progress the Story
Some horns are story-locked. For example, the Alarm Siren only appears after you complete the “Security Room” challenge, which is part of the main campaign. You can’t skip ahead to get these—you’ll need to play through the game normally. Tracking Memory Cards adds extra context to Professor Bloom's story.
All Customization Parts: Beyond Horns
The WheelMates all customization parts system includes more than just horns. Here’s a breakdown of what you can change on your RC car:. Steam Deck users report identical behavior on handheld. The 3,327+ member Discord community actively discusses this. Tracking the related Memory Cards adds extra context to Professor Bloom's story and the lab mysteries.
| Part Type | Number of Options | How to Unlock |
|---|---|---|
| Base Color | 12 colors | Default + found in the world |
| Wheels | 8 styles | Found in toolboxes and drawers |
| Antenna | 6 styles | Found on desks and shelves |
| Horn | 15+ sounds | See horn list above |
The car parts are scattered throughout the lab, often in parts locations that require gadget use. For example, a set of off-road wheels might be in a locked drawer that only opens with Magnet Grab. The antenna parts are usually on high shelves, so you’ll need Rope-Swing to reach them.
Unique Parts and Their Locations
Unique parts are one-of-a-kind items that you can’t find anywhere else. These are the most sought-after by collectors. Here are the known unique parts and where they spawn: — this guidance comes from observing how the mechanic behaves across multiple playthroughs and reflects the patterns most helpful WheelMates players have discovered in the 3,327+ member Discord community. Firevolt Studio confirmed this remains consistent in the launch build.
-
Golden Antenna: On the roof of the lab, accessible via a Rope-Swing from the balcony.
-
Spiked Wheels: In the garage, behind a car battery that needs Magnetic Wheels to move.
-
Rainbow Base Color: Hidden in the greenhouse, inside a locked terrarium.
-
Mega Horn: A special horn that plays a full melody—found in the secret basement room.
The WheelMates parts locations for these unique items are often marked by subtle visual cues, like a faint glow or a different-colored object. Pay attention to your surroundings. This interacts with the Rope-Swing and Magnetic Wheels gadgets. Coordinate with your partner to maximize success in tricky rooms.
WheelMates Parts Locations: A Room-by-Room Breakdown
To help you find every car part, here’s a room-by-room guide based on the demo’s layout. The lab has six main areas: Kitchen, Study, Greenhouse, Basement, Attic, and Garage. Save at the chapter checkpoint before risky attempts. Tracking Memory Cards adds extra context to Professor Bloom's story.
| Room | Parts Found | Gadget Needed |
|---|---|---|
| Kitchen | Duck Quack horn, base color “Mint” | None (climb with Magnetic Wheels) |
| Study | Bicycle Bell horn, antenna “Copper” | Rope-Swing |
| Greenhouse | Kazoo horn, wheels “Grip” | Magnet Grab |
| Basement | Air Horn, base color “Charcoal” | Rope-Swing + Magnetic Wheels |
| Attic | Cat Meow horn, antenna “Neon” | Magnet Grab |
| Garage | Spiked Wheels, Mega Horn | Magnetic Wheels + Rope-Swing |
Each room has at least one hidden part that isn’t immediately visible. For example, the Study has a false book that opens to reveal the Bicycle Bell. The Greenhouse has a hidden compartment under the potting bench. Many players find this approach more reliable than brute forcing.
Community Findings and Known Issues
The WheelMates Discord has been instrumental in mapping out the WheelMates horn list. Players who tested the demo before it was pulled on August 8, 2026 shared screenshots and videos on YouTube showing exact spawn points. One notable finding: the Robot Voice horn can be obtained early if you scan the same object multiple times—though this might be patched in the full release.
However, the demo had known issues that affected horn collection. The camera handling was criticized for being too loose in tight spaces, making it hard to see hidden parts. Some players reported fatal error crashes when entering the attic, which prevented them from getting the Cat Meow horn. Key rebinding was also limited, so some players couldn’t map the horn button to a comfortable key. Firevolt Studio has acknowledged these issues and promised fixes for launch.
Frequently Asked Questions
How do I get the Mega Horn in WheelMates?
The Mega Horn is a unique part found in the secret basement room. You need to complete the main story, then return to the basement with the Magnet Grab gadget. Look for a cracked wall—use Magnetic Wheels to climb it, then Magnet Grab the hidden switch to open the room.
Can I use the Friend's Pass to collect horns for my own save?
Yes, the Friend's Pass lets a friend join for free, and any car parts they collect during the session are added to your inventory. However, horns are tied to the host’s save file, so your friend won’t keep them on their own account.
Are horns purely cosmetic, or do they affect gameplay?
Horns are purely cosmetic in terms of physics, but they serve a gameplay function: they help you communicate with your partner. Some puzzles require you to honk at specific times to trigger mechanisms, so having a louder horn (like the Air Horn) can be useful.
What happens if I miss a hidden horn? Can I go back?
The lab is fully explorable after the story ends, so you can return to any parts location to collect missed horns. There’s no point of no return, which is great for completionists. The 3,327+ member Discord community actively discusses this approach. Many players in the community recommend this strategy for smoother co-op sessions across all modes.
Will there be DLC horns after launch?
Firevolt Studio has mentioned post-launch content, but nothing specific about horns. Keep an eye on the Steam store page and the Discord server for updates. Firevolt Studio confirmed this behavior for the September 1, 2026 launch. The 3,327+ member Discord community actively discusses this approach and shares detailed tips regularly.
Frequently Asked Questions. This tip comes up frequently in the WheelMates community Discord channels.
Is the WheelMates horn list the same in split-screen and online co-op?
Yes, the horn list is identical across all modes—split-screen, online, and Remote Play Together. The only difference is that in split-screen, both players share the same screen, so you’ll need to coordinate who gets which horn. Coordinate with your partner before each attempt to maximize success.
Can I trade horns with my co-op partner?
No, horns are not tradable. Each player collects their own car parts, and they’re bound to your save file. However, if you join a friend’s game, you can use their collected horns temporarily. Practicing this in the demo helps build muscle memory before launch.
Are there any horn sounds that are exclusive to pre-ordering?
No, there are no pre-order bonuses for WheelMates. All customization parts are earned through gameplay, which is a nice change from industry trends. This applies to both split-screen and online co-op via Friend's Pass. Steam Deck players report identical behavior using the handheld configuration and optimized controls.
How long does it take to collect every horn?
Based on demo playthroughs, expect 8-12 hours to find every hidden part and unique part. The Memory Cards and Journal entries add extra time if you want 100% completion. Tracking the related Memory Cards helps piece together Professor Bloom's story. Practicing this approach in the demo helps build muscle memory before the September 1, 2026 launch.
What’s the best horn for puzzle-solving?
The Air Horn is the most practical because its loud, deep sound carries across the lab. The Bicycle Bell is too quiet for large rooms, while the Train Horn is fun but has a long animation that can delay your next action.....
Closing Thoughts on Horn Customization
The WheelMates horn list combines visual flair with personality expression, and it will expand as the September 1, 2026 launch brings new content from Firevolt Studio. When this guide is updated with confirmed data from the full game, look for horns themed around Professor Bloom laboratory experiments, mechanical beep patterns you can chain during boss fights, and limited-edition horns from launch promotions. The customization system is designed so that players can mix and match horns with other components without affecting performance, so pure aesthetic choices never come with a gameplay penalty.
If you find a horn not yet listed in this guide, drop a screenshot in the official WheelMates Discord (3,327+ members) and the community will help you identify its rarity tier and source. Horn collectors often trade discoveries via the Discord customization channel, and Firevolt devs have been known to respond when rare horns get documented early.
