The Cycle Frontier Key Guide: Where to Find All Keys and Doors

The Cycle: Frontier presents players with locked doors and multicolored keys that unlock hidden rooms. This guide explains where to find every key and how to access the locked houses scattered across the map, in clear, practical steps that help players move from exploration to rewarding discoveries.

What are keys for and how are they found

Across the game’s locations, players will encounter keys in a spectrum of colors. These keys unlock rooms that guard valuable loot. The map shows several buildings and rooms, each opening with its matching key. Because the items are often tucked away in hard to reach places, most supplies in these secret zones remain untouched. Keys fall into four main tiers:

1. General white keys
2. Unusual green keys
3. Rare blue keys
4. Epic purple keys
5. Epic underground pink keys

Inside locked rooms, players can find armor, grenades, meds, ammo, cannon modules, and a range of weapons from common to epic. Once an item is picked up, it is wise to stash it in the pouch, as keys carry little weight and can be carried easily for future expeditions. Having the right key lets a player head into the next mission even with less than perfect gear. The essential step is locating the correct key and sprinting to the door that guards the secret chamber. The following sections pinpoint the exact door locations and describe how to search nearby coats, boxes, and safes to retrieve the key. A helpful interactive map is available in a separate article for those who want a visual aid.
