In ARC Raiders, keys play a major role in unlocking high-value loot and gaining an edge during raids. One of the more useful items you can come across is the Dam Surveillance Key. While it doesn't appear in a single guaranteed spot, knowing where to search—and how to use it—can greatly improve your efficiency and rewards.

The Dam Surveillance Key uses ARC Raiders randomized loot system, meaning it won't spawn in the same place every match. Instead of memorizing a fixed location, players should focus on areas where small utility items are most likely to appear.

Your best odds are in residential zones, which contain many interactive containers that can roll keys. Prioritize the following:

Drawers and cupboards:These are common in houses and apartments. Even if they seem empty most of the time, keys can spawn alongside minor loot.

Suitcases:Found scattered throughout living spaces, suitcases—locked or unlocked—are another solid source for keys.

Although the key is mainly tied to the Dam Battlegrounds, it can technically drop in other maps as well. Because of this, it's smart to loot carefully during every run instead of rushing objectives.Maximize your performance with top-tier ARC Raiders Items from MMOexp—your shortcut to success.
