The Patrol Car Key is a map-specific utility item that unlocks the rear door of a police patrol car. It shows up as an uncommon key in your inventory and is most relevant on the Blue Gate map, where the usable vehicle sits out of sight below ground.

Where to use the Patrol Car Key (Blue Gate)

Use this key in Blue Gate’s underground highway. Players have located the matching patrol car inside that tunnel network; interacting with the rear door while the key is in your inventory opens it. The car is not marked on the map, so budget time to sweep the underground lanes and alcoves rather than the surface roads.

Expect the usual PvPvE risks in Blue Gate: roaming ARC units and other raiders can make long searches costly, so route in with a purpose—drop in, head straight for the underground highway, and leave once you’ve made use of the key.

How to get keys in Arc Raiders

Keys are rare drops from loot containers across all maps, and they can also be taken off downed players. High-value areas attract more competition, so plan for contested fights if you’re farming. A key you find may not have a use on the map where you picked it up—plan your extractions and future raids accordingly.

How to use the Patrol Car Key during a raid

  • Bring the Patrol Car Key in your inventory on a Blue Gate raid.
  • Navigate to the underground highway section. Stay in the tunnels, not the surface.
  • Search for the police patrol car with a locked rear door. When close, an interaction prompt appears if the key is on you.
  • Unlock the rear door and quickly secure any loot.
  • Extract to keep what you’ve found.
Note: Items are only kept on successful extraction. If you’re not planning to route the tunnels, consider leaving the key in storage and bringing it only on runs dedicated to Blue Gate’s underground.

Can you just sell it?

You can sell the Patrol Car Key for 100 credits, but its practical value is in opening that specific patrol car in Blue Gate. If you’re progressing through Blue Gate regularly, hold it and plan a tunnel route; if Blue Gate isn’t in your rotation, converting it to credits is a simple fallback.

The short version: if you have the Patrol Car Key, set a Blue Gate run that prioritizes the underground highway. The car is down there, the key works on its back door, and your loot only counts once you’re out.
