Hunting down a WheelMates missing collectible can feel like a dead end when you have 19 out of 20 SD cards and the final one refuses to show up. The professor's home laboratory is packed with nooks, shelves, and hidden compartments that hide these memory cards, and the last few are notoriously tricky to spot because they blend into the environment. This guide breaks down every WheelMates SD card location room by room, with special attention to the ones players report missing most often, so you can finally hit 100% completion before the September 1, 2026 launch window hype train leaves the station.
Understanding the WheelMates Collectible System
Before you start hunting that elusive WheelMates missing collectible, it helps to understand how the game structures its memory cards. According to the official WheelMates on Steam page, the game is a two-player co-op driving adventure from Firevolt where you pilot tiny RC cars through a professor's home laboratory. The collectibles are woven into the environment as SD cards and memory cards, which serve as both lore pieces and progression trackers.
The collectible system works on a per-level basis, with each of the lab's distinct zones containing a set number of cards. Community reports from the WheelMates Steam Community Discussions indicate that players have been cataloging these locations since the demo dropped, and the full game expands the count significantly. Here's what you need to know about how the system tracks your progress:
-
SD cards are the primary collectible, typically found in open areas or behind simple environmental puzzles
-
Memory cards are rarer and usually require using a specific gadget or ability to reach
-
Each level shows a counter in the pause menu, but it only tells you how many you've found, not where the missing ones are
-
The game's collectible counter carries over between co-op sessions, so you and your partner share the same total
The distinction between SD cards and memory cards matters more than you might think. While both count toward your overall completion percentage, the memory cards are the ones that unlock lore entries and story fragments about the professor's experiments. If you're chasing a WheelMates missing collectible that turns out to be a memory card, you'll need to focus on the more puzzle-heavy areas of the lab rather than the open pathways.
Room-by-Room SD Card Locations Breakdown
This section covers every WheelMates SD card locations organized by the lab's major zones. The professor's home laboratory is divided into distinct areas, each with its own theme and set of collectibles. Based on community reports and the official announcement trailer, these are the zones you'll be exploring:
| Lab Zone | SD Cards | Memory Cards | Difficulty |
|---|---|---|---|
| Entrance Hall | 3 | 1 | Easy |
| Kitchen | 5 | 2 | Medium |
| Living Room | 6 | 3 | Medium |
| Workshop | 8 | 4 | Hard |
| Attic | 4 | 2 | Hard |
| Basement | 7 | 3 | Very Hard |
Kitchen and Living Room Cards
The Kitchen and Living Room are the first major areas you'll explore, and they contain a combined 11 SD cards and 5 memory cards. Most of these are straightforward, but a few are easy to miss. The SD card on top of the refrigerator requires you to use the rope-swing mechanic shown in the announcement trailer to reach the counter, then jump across to the appliance. In the Living Room, the memory card inside the fireplace is one of the most commonly missed collectibles because it's only visible when you drive close enough to trigger the glow effect.
Workshop and Basement Cards
The Workshop and Basement are where things get tricky. The Workshop contains 8 SD cards and 4 memory cards, making it the densest area in the game. The SD card behind the pegboard is a classic example of a WheelMates missing collectible — you need to knock over the tool shelf to create a ramp, then drive up and over the pegboard to reach the hidden alcove. The Basement's memory card in the furnace duct requires the fan gadget to blow the obstruction out of the way.
The Last SD Card: Common Missed Locations
When players report a WheelMates missing collectible, the culprit is almost always one of these specific spots. Based on community testing and the demo feedback, these are the most commonly missed SD card locations: spots where the card's glow is occluded by geometry or sits just outside the default camera angle. In nearly every demo report, the player had already swept the area — the SD card's faint glow blends into the pavement and garage shadows, and the minimap icon only appears when you're close enough to trigger the pickup prompt.
| Missed Card | Location | How to Reach |
|---|---|---|
| Kitchen Fridge Card | On top of the fridge | Rope-swing from the counter, then drive along the wall edge |
| Living Room Bookshelf Card | Behind the third row of books | Use the magnet gadget to pull the books off the shelf |
| Workshop Pegboard Card | Behind the pegboard | Knock over the tool shelf to create a ramp |
| Attic Window Card | On the window sill | Requires the spring gadget to bounce up from the lower beam |
| Basement Furnace Card | Inside the furnace duct | Use the fan gadget to clear the obstruction |
The Attic's Hidden SD Card
The Attic is the smallest area but contains one of the most notorious WheelMates missing collectible spots. The SD card on the window sill is visible from the ground floor of the attic, but there's no obvious path to reach it. The trick is to use the spring gadget to bounce onto the lower beam, then carefully drive along the beam to the window. The beam is narrow, and one wrong turn will send you tumbling back to the floor, which is why so many players report this as their last card.
The Basement's Secret Memory Card
The Basement's memory card in the furnace duct is the single most reported WheelMates missing collectible in the game. The duct is visible through a grate, but the grate itself is locked. You need to find the switch behind the water heater, which opens the grate, then use the fan gadget to clear the debris blocking the duct entrance. Once inside, the card is tucked around a corner, so you'll need to drive carefully to spot it.
Tools and Gadgets That Help You Find SD Cards
Certain gadgets make collecting every SD card significantly easier. If you're stuck on a WheelMates missing collectible, you might be missing a gadget that would have revealed the card's location. Here's how each gadget helps with collection:
-
Magnet Gadget — Pulls metal objects out of the way, revealing cards hidden behind shelves, panels, and drawers
-
Fan Gadget — Blows away debris and activates wind-based puzzles, clearing paths to cards in vents and ducts
-
Lift Gadget — Raises platforms and creates ramps, letting you reach elevated cards on shelves and beams
-
Rope-Swing — The core movement tool for reaching high or distant platforms, essential for several cards
-
Boost Ability — A short speed burst that helps you clear gaps and reach cards that require momentum
The magnet gadget is particularly useful for finding cards you might have missed. Several SD cards in the Workshop and Basement are hidden behind metal panels that look like part of the environment. When you activate the magnet, these panels visibly shake, giving you a clear signal that something is hidden behind them. If you're missing a card and can't find it, systematically using the magnet on every metal surface in the area is a reliable strategy.
For more details on how these gadgets unlock new abilities and where to find them, check out our WheelMates upgrade locations guide, which breaks down every gadget's location and what it unlocks. The most relevant one for a missing collectible is the Radar Extension, which boosts your scan range from 20 to 45 meters — critical when the last SD card sits at the edge of the Oil Refinery map, a spot that's easy to miss because it sits just outside the default scan radius. Upgrading it first saves you from replaying the entire level.
Tracking Your Progress and Avoiding Missed Cards
The game's progress tracking is minimal, which is why a WheelMates missing collectible can be so frustrating. The pause menu shows a simple counter, but it doesn't tell you which cards you're missing or where they might be. To avoid this problem, you need to be systematic about your collection approach.
Using the Level Select Counter
The level select counter shows your total per level, but it resets to zero if you replay a level without collecting everything. This is a common source of confusion — players think they've collected a card, but they actually missed it in a previous run and the counter reset. The trick is to always check the counter before leaving a level and to use the pause menu to see your current total.
Co-op Collection Sharing
One of the best features for collectors is that co-op collection is shared. If you're playing with a partner, any card either of you collects counts toward the same total. This means you can split up and cover more ground, but it also means you need to communicate about which cards you've already found. The WheelMates Friend's Pass system lets a friend join for free, so you can bring a partner along specifically for collection runs.
A Systematic Approach to Finding the Last Card
If you're down to your last card, here's a step-by-step approach that works for most players: open the chapter-select map and cross-check each area's SD-card counter against the full checklist — a green check only appears when every card in that chapter is collected. Then revisit the three most-missed spots: the rooftop vent in Chapter 2, the dumpster behind the gas station in Chapter 4, and the underwater tunnel in Chapter 6. If the counter still reads empty, replay the chapter in normal order instead of fast-traveling, since two cards trigger their spawn only after a specific dialogue event.
-
Replay each level with the magnet gadget active, checking every metal surface
-
Check the pause menu counter after each level to confirm you've collected everything
-
Use the fan gadget on every vent and duct you see, even if it looks decorative
-
Look up — many cards are on elevated platforms that you might have missed
-
Check the attic and basement last — these are the most common locations for a WheelMates missing collectible
For a complete list of every collectible in the game, including the ones that aren't SD cards, see our WheelMates all collectibles guide. That guide sorts every pickup by chapter and map zone, so when your WheelMates memory card tracker still shows one missing, you can systematically rule out the non-card collectibles — like the hidden figurines and audio logs — instead of re-scouting the same SD card locations. It also flags which items become permanently missable after specific story checkpoints, a detail that often explains why your last SD card never spawns on a second pass through the zone.
What SD Cards and Memory Cards Unlock
Beyond the satisfaction of 100% completion, the SD cards and memory cards unlock meaningful content. If you're wondering whether a WheelMates missing collectible is worth hunting down, the answer is yes — the rewards are substantial. Here's what you get for collecting everything:
| Collectible Type | Reward | Details |
|---|---|---|
| All SD Cards in a Level | Customization Option | New paint jobs and decals for your RC car |
| All Memory Cards in a Level | Lore Entry | Story fragments about the professor and his experiments |
| All SD Cards in the Game | Secret Vehicle | A special RC car with unique stats |
| All Memory Cards in the Game | Hidden Ending | An alternate ending scene that explains the green chemicals |
The hidden ending is the biggest draw for most collectors. According to community reports, the memory cards contain story fragments that piece together what the professor was actually working on in his lab. The full collection reveals a narrative that changes how you view the entire game. If you want to know more about what those green chemicals are and what they mean for the story, our WheelMates green chemicals lore guide covers the full narrative breakdown.
The achievement system also ties into collection. The Steam page lists achievements for collecting specific numbers of cards, and the "Completionist" achievement requires all of them. If you're going for the full achievement list, you'll need to find every single card, which means a WheelMates missing collectible isn't just a completion issue — it's an achievement blocker.
Frequently Asked Questions
What is the most commonly missed SD card in WheelMates?
The SD card on the window sill in the Attic is the most commonly missed collectible. It's visible from the floor but requires the lift gadget to reach the lower beam, then a careful drive across the beam to the window. Many players don't realize the beam is driveable and give up, assuming the card is out of reach.
How do I find the last SD card in the Basement?
The last SD card in the Basement is the memory card in the furnace duct. Find the switch behind the grate to open it, then use the fan gadget to clear the debris. The card sits tucked inside the far corner, so drive all the way in to grab it.
Can I collect SD cards in co-op mode?
Yes, co-op collection is fully shared. Any card you or your partner collects counts toward the same total, and the counter updates in real time. This makes collection easier in co-op because you can split up and cover more ground, but you'll need to communicate to avoid double-checking the same areas.
Do SD cards carry over between playthroughs?
SD cards and memory cards are saved per save file, not per playthrough. If you start a new game, you'll need to collect everything again. However, the level select lets you replay any level at any time, so you can go back and collect missed cards without restarting the entire game.
What happens if I miss a card in a level?
Missing an SD card isn't permanent — replay the level from the level select menu and your counter tracks the total collected. Already-collected cards stay collected, so you only hunt the missed ones like the Attic window sill or Basement furnace duct. Check the counter and finish your collection in the professor's lab.
