- Course to Venus vent key: Search the fridge after the game reaches nighttime.
- Black container: Interact with the black lunchbox or container inside the fridge.
- Event trigger: Go upstairs after eating the lunchbox to advance the sequence.
- Final use: Pass through the door, then use the key on the vent.
Course to Venus Vent Key Route
The Course to Venus vent key route is tied to a short nighttime event involving the fridge, a black lunchbox, the upstairs area, and a door with a vent. The sequence is easiest to complete when you follow the object order instead of trying to use the key immediately.
The available route can be summarized as:
| Order | Location or action | Required result |
|---|---|---|
| 1 | Wait until nighttime | The fridge interaction becomes available |
| 2 | Search the fridge | Find the black container or lunchbox |
| 3 | Eat the black lunchbox | Trigger the next part of the event |
| 4 | Go upstairs | Continue the sequence |
| 5 | Pass through the door | Reach the vent interaction |
| 6 | Use the key on the vent | Advance the objective |
Follow the sequence in order. Searching the fridge before nighttime or visiting the vent too early may not advance the event.
Video Highlights:
- The video is labeled for the Course to Venus storyline.
- Use it as a visual reference for the general event context.
- Match the in-game object order against the written route below.
The key point is that the vent is the final interaction in this chain. The fridge search and lunchbox action come first, while the upstairs movement functions as the event transition. Treat the route as a progression trigger rather than a standard item hunt.
Find the Fridge Item at Night
The first stage begins at night. Search the fridge and look for the black item described in the available walkthrough material as a black container or black lunchbox. The wording may vary between descriptions, but the important detail is the dark container inside the fridge.
Do not skip the nighttime condition. If the correct object is not visible or cannot be interacted with, advance the in-game time and check the fridge again.
| Checkpoint | What to inspect | What success looks like |
|---|---|---|
| Time | Current in-game period | The scene is nighttime |
| Location | Fridge | The fridge can be searched |
| Object | Black container or lunchbox | The item can be selected |
| Interaction | Eat the item | The next event phase begins |
The fridge step is time-sensitive within the route. If the item does not appear, confirm that the scene is set to nighttime before changing locations.
Nighttime Check
Confirm that the game has reached night before searching the fridge. This is the first route condition.
Fridge Search
Open or inspect the fridge and identify the black container or lunchbox described for this event.
Correct Interaction
Eat the lunchbox rather than treating it as a collectible to carry elsewhere. This advances the sequence.
The item’s role is practical: it starts the next phase. Avoid spending time searching unrelated rooms before completing this interaction. Once the lunchbox action registers, move directly toward the upstairs area.
Trigger the Upstairs Event
After eating the black lunchbox, head upstairs. This movement is not just a change of scenery; it continues the event sequence and prepares the route toward the door and vent.
Use the following progression table to confirm that each transition has occurred:
| Stage | Action | Route status |
|---|---|---|
| A | Eat the black lunchbox | Fridge phase completed |
| B | Leave the fridge area | Event remains active |
| C | Go upstairs | Upstairs sequence triggered |
| D | Continue through the available route | Door area becomes relevant |
| E | Pass through the door | Vent can be used as the next objective |
If the upstairs movement has triggered correctly, the next target is the door. You should not need to repeat the fridge search unless the lunchbox interaction failed to register.
Finish the Fridge Interaction
Make sure the black lunchbox or container has been eaten. Simply inspecting it may not be enough to activate the next phase.
Move Upstairs
Leave the fridge area and travel upstairs. This movement triggers the next part of the sequence.
Locate the Door
Continue through the upstairs route until you reach the door associated with the event.
Go Through the Door
Pass through the door so the vent becomes the next usable point in the route.
The route is linear, so repeated interaction with unrelated objects can make the event feel stalled. Once the lunchbox has been eaten, prioritize the stairs and then the door.
Use the Key on the Vent
The final part of the Course to Venus vent key walkthrough is performed after you pass through the door. At that point, use the key on the vent. The key is not the first objective in the chain; it becomes useful only after the nighttime fridge event and upstairs transition are complete.
| Final step | Correct action | Common mistake |
|---|---|---|
| 1 | Pass through the door | Searching for the vent before entering the area |
| 2 | Identify the vent | Interacting with unrelated objects |
| 3 | Select the key | Trying to use the item at the fridge |
| 4 | Apply the key to the vent | Leaving before the interaction registers |
The key belongs at the vent after the door transition. If the vent does not respond, retrace the route and confirm that the black lunchbox was eaten and the upstairs event was triggered.
The key-use sequence is short, but the preceding triggers matter. A failed vent interaction usually points to an earlier incomplete step rather than a missing alternate key location. Check the nighttime condition, fridge item, lunchbox action, upstairs movement, and door transition in that order.
For reference, the relevant community walkthrough can be reviewed in the Course to Venus comments post, which identifies the nighttime fridge search, black lunchbox interaction, upstairs trigger, door transition, and vent use.
Troubleshooting Checklist and FAQ
Use this checklist if the vent key route does not advance. It focuses on the confirmed sequence and avoids unnecessary backtracking.
Vent Key Route Checklist:
- Wait until nighttime before searching the fridge
- Find the black container or lunchbox inside the fridge
- Eat the lunchbox to trigger the next phase
- Go upstairs and continue to the event door
- Pass through the door and use the key on the vent
Do not assume the key is missing if the vent fails to respond. First verify that every earlier trigger completed in the listed order.
| Problem | Likely checkpoint | Recommended response |
|---|---|---|
| The fridge has no target item | Time condition | Return at nighttime and search again |
| The item is visible but the route does not advance | Interaction condition | Eat the black lunchbox rather than only inspecting it |
| Upstairs movement changes nothing | Event trigger | Confirm the lunchbox action registered |
| The door route seems unavailable | Transition condition | Continue upstairs after completing the fridge phase |
| The vent does not respond | Sequence condition | Recheck the nighttime, lunchbox, stairs, and door steps |
Q: When can I find the Course to Venus vent key?
Begin the route at nighttime. Search the fridge, find the black container or lunchbox, and complete the eating interaction before heading upstairs.
Q: What should I do with the black lunchbox?
Eat the black lunchbox after finding it in the fridge. This action triggers the next phase of the event and leads you toward the upstairs route.
Q: Where is the key used?
After going upstairs and passing through the door, use the key on the vent. The vent is the final interaction in this route.
Q: Why does the vent key not work?
Check the event order. The game expects the nighttime fridge search, lunchbox interaction, upstairs movement, and door transition before the key is used on the vent.
The most reliable approach is to treat this as a chain of event triggers. Start at night, complete the fridge interaction, move upstairs, pass through the door, and then use the key on the vent. This order keeps the route focused and reduces unnecessary searching.
