The Locked Gate event has returned to ARC Raiders as part of the Cold Snap update, and you can get some fantastic rewards by gaining access to the secret room.
To gain access, you’ll have to find four Security Code keys that are spread all over the Blue Gate map. Finding the keys will be your main task since the rest of the steps are pretty straightforward. If you’re confused about how to find them, this guide will make your life easier.
How to find all Locked Gate Security Codes in ARC Raiders
There are four Locked Gate Security Codes to find. The four keys, along with the Locked Gate room, are all situated in the Blue Gate map. You can find the Security Code keys in any order of your liking. You don’t need to find them all on the same raid, either, given that you manage to return with them (or place them in a Safe Pocket).

The screenshot above has the locations of all four Security Code keys.
- The Ancient Fort location has a lot of containers, and the code key will be in any one of them.
- Raider’s Refuge is an easier area to search as the containers are fewer in number.
- The same also applies to Reinforced Reception.
- Pilgrim’s Peak has plenty of searchable containers.
While the Security Code keys are all available in containers, finding them will be dependent on your luck. What you’ll want to do is to patiently go through every container that you can find at the locations. If you’re lucky, you could find the key from the very first container. If you go through all the containers, it’s impossible to miss the Security Code keys.
Once you have all four, head to the Checkpoint POI, and you’ll come across a room requiring all four keys. Enter them to unlock the room and loot everything that you can find inside. We have a detailed guide on how to open the room and what to expect. As always, be careful of other players who might try to ambush and steal your loot.
