Some of the doors in ARC Raiders conceal very valuable rewards, and one of the most significant items to find is the Dam Surveillance Key. This guide will reveal to you where to find the key, how you can use it to enter the locked room in the Dam, and what to be aware of when you go in for the high-level loot within.
Where to Locate the Dam Surveillance Key

The Dam Surveillance Key is dropped at random but can usually be found in cabinets and drawers in residential-type buildings. Some reliable spots are the second floor of the Research & Administration building and the Ruby Residence building. Remember that the key will not always be found in the same location, so a little searching may be required.
Using the Key

Once you’ve got the Dam Surveillance Key, make your way to the Water Treatment Control area at the front of the Dam. Enter the building from the main entrance, then take the first right and immediately turn right again. Ahead of you, you’ll find the door that requires the Dam Surveillance Key — simply use the key to unlock it and claim the loot waiting inside.
Stay Prepared
This part of the Dam is well-guarded by ARC robots, since the loot inside is usually top-tier. On top of that, other ARC Raiders may be around trying to snatch your rewards. Be ready for both NPC and player threats before stepping in.
With this guide, you now know where to find the Dam Surveillance Key, how to use it, and what to watch out for. Grab your key, claim your loot, and keep exploring ARC Raiders — there’s plenty more hidden in every corner.
