The Blue Gate Communication Tower Key is a Rare key in ARC Raiders used to open a locked room beneath the Communication Tower at Pilgrim’s Peak on The Blue Gate. The room contains several loot containers and is also connected to Apollo’s Groundbreaking quest.
Finding the correct location can be confusing because the Communication Tower does not have its own clearly named map marker. Players need to navigate to Pilgrim’s Peak, enter the lower facility, and follow the interior route toward the locked room.
This guide explains where to use the Blue Gate Communication Tower Key, how to get it, what loot is inside, how Groundbreaking works, and what to do if you lose the key.
Quick Answer
The Blue Gate Communication Tower Key opens a locked room beneath the Communication Tower at Pilgrim’s Peak.
The easiest approach is to enter from the southern side, move through reception, go through the door at the end, turn right, and follow the corridor until you reach the locked door.
Inside the room, players can find:
- 2–4 Server Racks
- 1 Weapon Box
- 2–3 Drawers
- 2–3 Resource Crates
- 1–6 Loose Items
The key is consumed after use, so check whether another Raider has already opened the room before spending yours.

Key Takeaways
The key is easy to understand once you know the correct destination. Most problems come from searching for the wrong map marker or missing the lower-level entrance.
Important points include:
- The key is used at Pilgrim’s Peak.
- The locked room is beneath the Communication Tower.
- The tower does not have its own named POI marker.
- The key can be obtained through scavenging or Groundbreaking.
- It is consumed after use.
- Groundbreaking provides an optional spare-key interaction.
- Successful extraction is not required for completed Groundbreaking objectives.
- The final photo objective is at the southernmost Abandoned Housing Project building.
What Is the Blue Gate Communication Tower Key?
The Blue Gate Communication Tower Key is a map-specific access item. It opens one particular locked room at Pilgrim’s Peak and does not work with every locked door on The Blue Gate.
Its most important characteristics are:
- Rarity: Rare
- Weight: 0.25
- Stack size: 1
- Sell value: 100
- Map: The Blue Gate
- Main use: Opening the Communication Tower loot room
The key becomes especially useful during Groundbreaking because access to the room is required to investigate the construction-research whiteboard.
Where Do You Use the Blue Gate Communication Tower Key?
Use the Blue Gate Communication Tower Key at Pilgrim’s Peak in the northern or northeastern portion of The Blue Gate.
The room is not at the top of the tower. Instead, you need to enter the lower facility beneath the Communication Tower and follow the interior corridor.
Location at a Glance
| Step | What to Do |
|---|---|
| 1 | Travel to Pilgrim’s Peak |
| 2 | Locate the Communication Tower |
| 3 | Enter the lower facility |
| 4 | Move through reception |
| 5 | Follow the corridor |
| 6 | Unlock the door on the right |
Players who search only the exterior or upper portion of the tower can easily miss the room.
Why Can’t I Find the Communication Tower on the Map?
The Communication Tower does not have a separate map marker labeled with that exact name. This is why many players assume they are looking in the wrong area.
Your real destination is Pilgrim’s Peak. Once you arrive, use the tall tower itself as your visual landmark.
Remember this simple route:
- Pilgrim’s Peak
- Communication Tower
- Lower facility
- Locked room
Exact Route to the Locked Door
The southern entrance provides one of the easiest routes to remember. It takes you directly into reception and gives you a simple interior path toward the locked room.
Follow these steps:
- Enter Pilgrim’s Peak from the south.
- Move through the reception area.
- Go through the door at the far end.
- Turn right.
- Continue down the corridor.
- Look for the locked door on your right.
The Blue Gate Communication Tower Key opens this room.
How Do You Get the Blue Gate Communication Tower Key?
There are two main ways to obtain the key. One comes from ordinary gameplay, while the other is tied directly to Groundbreaking.
Scavenging
The Blue Gate Communication Tower Key can appear through normal scavenging. However, it should not be treated as having one permanently guaranteed normal-world container.
Keep in mind:
- The key can appear during regular looting.
- Normal scavenging is random.
- You should not expect the same container to produce it every raid.
Groundbreaking
Apollo also gives you a Blue Gate Communication Tower Key when you begin Groundbreaking after completing Deciphering The Data.
The quest involves:
- Entering the locked Pilgrim’s Peak room
- Investigating the whiteboard
- Finding the pictured building
- Photographing the Abandoned Housing Project
Key Sources
| Key Source | Availability |
|---|---|
| Normal key | Random scavenging |
| Apollo quest key | Granted with Groundbreaking |
| Spare key | Optional quest interaction |
Where Is the Groundbreaking Spare Key?
Groundbreaking provides a backup option if you lose Apollo’s original key or want to complete the optional spare-key objective.
Enter Pilgrim’s Peak from the south and check behind or beneath the reception desk. The quest interaction in this area can provide another Blue Gate Communication Tower Key.
The important distinction is:
- It is connected to Groundbreaking.
- It is a quest-specific interaction.
- It should not be treated as a guaranteed normal key spawn.
Is the Blue Gate Communication Tower Key Single Use?
Yes. The Blue Gate Communication Tower Key is single use.
Once you unlock the matching room, the key is consumed. Patch 1.11.0 also corrected an exploit that had allowed players to keep used room keys.
Before spending your key, check:
- Whether the door is already open
- Whether you have enough backpack space
- Whether the area is reasonably safe
- Whether Groundbreaking is active
- Whether enough raid time remains
If another Raider has already opened the room, you may be able to enter without using your own copy.
What Happens If the Door Is Already Open?
An open door can save your key, but it may also indicate that another player is nearby.
Before entering, listen carefully and check the surrounding corridor. The room may already be partially looted, or another Raider may still be inside.
Possible situations include:
- Another player is still looting.
- The room was recently cleared.
- A squad is nearby.
- Some containers may already be empty.
- Someone may be watching the entrance.
Saving the key is useful, but staying alive is more important.
What Loot Is Inside the Communication Tower Room?
The room contains a mixture of technology, resource, weapon, and general loot containers. The container layout makes it useful, but exact item quality still varies from raid to raid.
| Loot Container | Listed Quantity |
|---|---|
| Server Racks | 2–4 |
| Weapon Box | 1 |
| Drawers | 2–3 |
| Resource Crates | 2–3 |
| Loose Items | 1–6 |
Using the Blue Gate Communication Tower Key does not guarantee one specific weapon or a fixed loot value.
Main Loot
The Server Racks are one of the room’s most attractive features because several can appear in a relatively small area. The Weapon Box and Resource Crates add additional value, while Drawers and loose items can provide useful extra materials.
Make sure you check:
- Server Racks
- Weapon Box
- Resource Crates
- Drawers
- Desks and shelves
- Loose items on nearby surfaces
Is the Communication Tower Room Worth Opening?
In many raids, yes. The Blue Gate Communication Tower Key has a listed sell value of only 100, while opening the room gives you access to several dedicated loot containers.
However, using the key is not automatically the best choice in every situation. Your inventory, route, and nearby player activity should all influence the decision.
Use the key when:
- Pilgrim’s Peak is already on your route.
- You are completing Groundbreaking.
- You have enough backpack space.
- The area appears manageable.
- Enough raid time remains.
Consider saving it when:
- Your backpack is full.
- Heavy fighting is nearby.
- You are carrying valuable equipment.
- Very little raid time remains.
- Another Raider has already opened the room.
Blue Gate Communication Tower Key and Groundbreaking
The key plays an important role in Apollo’s Groundbreaking quest, which becomes available after Deciphering The Data.
Groundbreaking takes you from Pilgrim’s Peak to the Abandoned Housing Project and combines a locked-room interaction with a later photography objective.
Groundbreaking Overview
| Detail | Information |
|---|---|
| Quest | Groundbreaking |
| Trader | Apollo |
| Map | The Blue Gate |
| Area | Pilgrim’s Peak |
| Key | Blue Gate Communication Tower Key |
| Research Objective | Whiteboard |
| Final Area | Abandoned Housing Project |
| Reward | Warden Outfit Tangerine Color + 1 Power Rod |
How to Complete Groundbreaking
Groundbreaking is straightforward once you understand the route. The main challenge is reaching Pilgrim’s Peak safely, opening the room, and then identifying the correct building for the final objective.
Step 1: Accept the Quest
Complete Deciphering The Data and accept Groundbreaking from Apollo.
You receive a Blue Gate Communication Tower Key when the quest begins.
Step 2: Protect the Key
Place the key in a Safe Pocket if possible while traveling to Pilgrim’s Peak.
This reduces the chance of losing an important quest item before you reach the locked door.
Step 3: Reach Pilgrim’s Peak
Travel toward the northern or northeastern area of The Blue Gate.
Pilgrim’s Peak can attract other Raiders, so stay alert as you approach.
Step 4: Get the Spare Key
If needed, check behind or beneath the reception desk.
The optional quest interaction there can provide another Communication Tower Key.
Step 5: Find the Locked Room
From reception:
- Go through the door at the end.
- Turn right.
- Follow the corridor.
- Find the locked door on your right.
Step 6: Enter the Room
Use the Blue Gate Communication Tower Key if the door is still locked.
If another Raider already opened it, you may be able to keep your own key.
Step 7: Investigate the Whiteboard
Inside the room, find the construction-research whiteboard and interact with it.
Do not leave after looting without completing this interaction if Groundbreaking is active.
Step 8: Find the Target Building
Travel south to the Abandoned Housing Project.
The required target is the southernmost building in the group.
Step 9: Take the Photo
Approach the building from its north side.
Find the photography interaction and complete it to progress the quest.
Groundbreaking Route Summary
| Objective | Location |
|---|---|
| Reach Pilgrim’s Peak | Northern/northeastern Blue Gate |
| Find spare key | Reception desk |
| Find locked room | Corridor beyond reception |
| Research construction | Whiteboard inside room |
| Find target building | Abandoned Housing Project |
| Correct building | Southernmost building |
| Photo location | North side |
Do You Need to Extract to Complete Groundbreaking?
No. Completed Groundbreaking objectives can count even if you fail to successfully extract afterward.
This means your priority should be completing the required interactions first. Extraction becomes important mainly if you want to keep ordinary loot collected during the raid.
Focus on:
- Entering the locked room
- Interacting with the whiteboard
- Reaching the Abandoned Housing Project
- Photographing the correct building
What Happens If You Lose the Communication Tower Key?
Losing one copy does not necessarily block Groundbreaking permanently. There are several ways to recover or continue.
You can:
- Use the optional Groundbreaking spare key near reception.
- Find another key through normal scavenging.
- Enter the room if another Raider already unlocked it.
The quest therefore has more than one possible recovery route.
Should You Put the Key in a Safe Pocket?
If Groundbreaking is your main objective, protecting the Blue Gate Communication Tower Key is a sensible choice.
A Safe Pocket can help ensure you reach Pilgrim’s Peak with the item needed for the locked room. Once the door has been opened, you can change your inventory priorities.
Best Solo Strategy
Solo Raiders should focus on awareness rather than speed. Pilgrim’s Peak can attract players interested in quests, locked-room loot, or regular rotations through The Blue Gate.
Before entering the facility, listen for:
- Footsteps
- Gunfire
- Doors opening
- Looting
- ARC combat
Make sure you have a reasonable exit route before spending your key.
Best Squad Strategy
Squads can reduce risk by giving each player a different responsibility. One player can handle the key while the others watch approaches and listen for movement.
A simple setup is:
- Player 1: Carries and uses the key.
- Player 2: Watches the main approach.
- Player 3: Covers the rear or another entrance.
Avoid having everyone focused on loot at the same time.
Efficient Way to Loot the Communication Tower Room
The safest approach is to loot quickly and follow a predictable order. Spending too long comparing minor items gives other Raiders more time to reach your position.
A good order is:
- Check that nobody followed you.
- Search the Server Racks.
- Open the Weapon Box.
- Check Resource Crates and Drawers.
- Pick up useful loose items.
- Interact with the whiteboard if Groundbreaking is active.
- Organize your backpack and leave.
The goal is to take the most useful loot without staying inside longer than necessary.
Common Blue Gate Communication Tower Key Mistakes
Most mistakes happen because players misunderstand the map location, use the key too early, or forget part of the Groundbreaking objective.
Avoid these common problems:
- Searching for a Communication Tower marker: Navigate to Pilgrim’s Peak instead.
- Searching the top of the tower: The locked room is in the lower facility.
- Using the key immediately: Check whether the room is already open.
- Confusing the spare key with a normal spawn: The reception interaction is tied to Groundbreaking.
- Forgetting the whiteboard: It is required for quest progression.
- Photographing the wrong building: Use the southernmost Abandoned Housing Project building.
- Entering with a full backpack: Leave enough room for valuable loot.
- Expecting guaranteed rare loot: Exact drops vary between raids.
Blue Gate Communication Tower Key Troubleshooting
If something does not seem to work, first confirm that you are at the correct Pilgrim’s Peak location and that the appropriate Groundbreaking objective is active.
| Problem | What to Check |
|---|---|
| Cannot find Communication Tower | Go to Pilgrim’s Peak |
| Cannot find locked door | Enter reception, use the end door, then turn right |
| Key does not work | Confirm you are at the correct locked room |
| Door already open | Another Raider may have unlocked it |
| Quest key was lost | Use the optional spare-key interaction |
| Cannot find spare key | Check behind or beneath reception during Groundbreaking |
| Groundbreaking does not progress | Interact with the whiteboard |
| Cannot find photo target | Go to the southernmost Abandoned Housing Project building |
| Photo prompt missing | Approach from the north side |
| Key disappeared | Keys are consumed after use |
Blue Gate Communication Tower Key vs Other Blue Gate Keys
The Communication Tower Key is only one of several location-specific keys found on The Blue Gate.
Examples include:
- Blue Gate Cellar Key
- Blue Gate Village Key
- Blue Gate Confiscation Room Key
- Blue Gate Communication Tower Key
These keys are not interchangeable. The Blue Gate Communication Tower Key specifically belongs to the locked Communication Tower room at Pilgrim’s Peak.
Blue Gate Communication Tower Key 2026 Update History
Several updates have affected room-key behavior and Groundbreaking. These changes are worth knowing because older guides may describe mechanics that no longer behave the same way.
Patch 1.11.0
Patch 1.11.0 fixed an exploit that allowed players to retain room keys after using them.
This supports the intended single-use behavior of the key.
Patch 1.13.0
Patch 1.13.0 added more interactions to Groundbreaking’s final objective.
The change helped make the quest easier to complete reliably.
Patch 1.17.0
Patch 1.17.0 improved quest guidance and multi-step objective information.
Because ARC Raiders is a live-service game, Blue Gate Communication Tower Key mechanics and related quest details may still change through future updates.
