Delta Force Key Cards Use Explained

Before we dive into the list, here’s a quick rundown of how key cards work. Each key card has a total of 20 uses when found in-game or purchased at auction. If you acquire a copy version through missions or events, it will only have 4 total uses. Here's how the uses are consumed:

• Easy difficulty: 1 use per opening
• Normal difficulty: 2 uses per opening
• Hard difficulty: 4 uses per opening

Once used, the key card can no longer be auctioned. So, if you want to make a profit, avoid using it before selling it!

Key Card Ratings and Locations

🔑 Route-Access Key Cards You Must Buy!

🔹 Essential for movement and avoiding danger zones.

Employee Passage Key Card

The Employee Passage Key Card, priced at 710,000, is essential for navigation in Space City, providing access to two key passageways rather than unlocking loot. The first location, on the eastern side, is found in a building near a spawn point and unlocks a door leading to a pipe passage, offering a shortcut to the central area. Without it, players must take a longer and riskier route via the Central Command Bridge. The second location, on the western side, unlocks a gate that allows quick access from Central Command Bridge to the southern area, preventing players from having to cross the central bridge, a high-traffic danger zone. This key card is absolutely vital for safe and strategic movement, making it a must-have for every player in Space City.

West Gate Key Card

The West Gate Key Card, priced at 720,000, provides access to an alternative route rather than unlocking loot. While not as versatile as the Employee Passage Key, it still plays a crucial role in navigation. It opens a gate on the western side of the central compound, offering direct access to the Buoyancy Lab or Centrifuge Facility. This key is beneficial for players spawning at the Southern Dormitory and, in some cases, the Northern Dormitory, as it provides a safer shortcut. Without this key (or the Employee Passage Key), players from these spawns must take a long and dangerous route through the Central Command Bridge, a high-risk area. 

Eastern Suspension Bridge

The Eastern Suspension Bridge Key Card, priced at 1.5 million, is the most expensive route-unlocking key in Space City. Located in the southeast corner of the core area, it is primarily useful for players who spawn at the Water Tank Station in the southeastern tip of the map. With this key, players can lower the bridge and quickly cross into the Black Chamber, avoiding a potentially dangerous route through the Assembly Room, where enemy teams might be present. Without the key, players must take a longer, riskier path through the Employee Passage or the Command Bridge. However, the bridge is exposed, making players vulnerable to gunfire, especially from teams moving down from Launch Site and Employee Passage 2. While not as universally useful as the Employee Passage or West Gate key cards, it is still a valuable option, particularly for those spawning in the southeast.

💰 Loot-Based Key Cards

🔹 These key cards unlock loot rooms. Some are high-risk but rewarding.

P.S:  ☆ indicates a chance for "Heart of Africa" to spawn on the desks in these rooms. Except for the CEO's room, all other rooms can be observed through the glass from outside before deciding whether to unlock them.

Black Chamber Server Room

The Black Chamber Server Room Key Card, priced between 3.7 to 4.5 million, grants access to a high-value loot room in the Black Chamber, located in the southeastern part of the four core buildings. To reach it, players should enter from the southern entrance, take the stairwell to the left, and go up one floor. The server room, accessible through a single entrance, is packed with loot, including seven containers, one piece of clothing, two computer cases, one storage box, one premium storage box, and two servers. While the key card is expensive, the abundance of loot makes it a profitable investment. However, given its high resale value, players may also consider selling it instead. 

CEO Office Reception Room

The CEO Office Reception Room Key Card is the most expensive key card in Space City, ranging from 4.8 to 5.8 million. It grants access to a high-value loot room within the CEO’s office, which is located at the top of the middle building in the core area. Players can reach this area via the Buoyancy Lab or the Black Chamber, using ladders or stairwells to ascend. Despite its name, the CEO Office Reception Room functions more like a storage room for valuables, containing display cases and two large safes. Loot inside includes one large weapon crate, two pieces of clothing, and two large safes, offering significant rewards. However, this area is one of the most dangerous in the game, as multiple teams frequently fight for control of the CEO’s office. Due to its high price, the room is not looted often, making it a good target for late-game looting if players can sneak in undetected. And remember to check the showcase! There is the potential to loot the Heart of Africa here!

Assembly Workshop 2F Lab

The Assembly Workshop 2F Lab Key Card costs 780,000 and unlocks a loot room on the eastern side of the map in the Assembly Room, located upstairs at the back of the building. Players can access it via the metal stairs, and the room has two entrances, meaning if one side is already looted, the other might still be untouched. The bulletproof glass provides visibility over the Assembly Room while keeping players safe inside. The room contains five loot containers, including one piece of clothing, one courier carton, one drawer, one computer case, and one premium storage box, along with additional items that may spawn on the desks and floor. While the loot quality isn't exceptional, the location is relatively low risk compared to the central core areas of Space City. Since it is not frequently looted, it can be a good investment for players looking for decent loot with lower risk. 

No.3 Dormitory Back Room

The No.3 Dormitory Back Room Key Card costs 860,000 and unlocks a small bedroom in Dormitory Building No.3.  The dormitory area has three buildings, each marked with a large 1, 2, or 3.  To find this room, enter Building No.3, go upstairs to the back, and use the key card to unlock the door.  Inside, you’ll find two clothing items that can be searched and one suitcase.  The room has two doors: the main entrance from the upstairs corridor and an optional balcony exit, which requires an additional key card use.

The bulletproof glass allows players to check their surroundings while looting, and clothing items have a higher chance of dropping key cards, which can be beneficial. 

Test Range Glass Room

The Test Range Glass Room Key Card costs 1.1 million and unlocks a small room in the Test Range area. To find it, enter the north entrance where the reception area is located. The Glass Room is situated on the same floor, just to the side of the reception. Inside, the room contains two loot containers: one large weapon crate and one regular weapon crate, with the potential to hold a single gun. The room has bulletproof glass and only one entrance, making it somewhat secure. Although the loot is minimal for the cost, the bulletproof glass allows players to check inside. You can unlock it after seeing a high value item inside! 

Test Range Data Center

The Test Range Data Center Key Card costs 1.4 million and grants access to a loot-rich room on level two of the Test Range. You can reach it by entering through the south entrance and turning right, or by heading up the stairs from reception. This room contains several valuable containers, including one large weapon crate, two servers, and one storage box. Servers typically provide two items each and have a high chance of yielding valuable single-slot items, making them ideal for storing in your safe box for guaranteed profit. However, the room has only one entrance, meaning you can easily get trapped inside. Despite this risk, the quantity and quality of loot make it decently rewarding.

Test Range Core

The Test Range Core Key Card costs 3.6 million and unlocks a room on the top floor of the Test Range, overlooking the main test range area. The room has two doors and bulletproof glass, allowing you to observe the surroundings, but escaping can be difficult if an enemy team tries to trap you inside. Inside, you'll find one large safe, one piece of clothing, and some loot on desks and the floor. While large safes are a great source of high-end loot, having only one for the high price of 3.6 million makes this key card poor value. However, there is the potential to loot the Heart of Africa here, so you can check the table through the glass before you unlock the room.
