Find the 5 keys is a mission in Into the Nexus, taking place in the Hagrow Swampland on planet Thram. Ratchet and Clank find a Gadgetron Corporation vault amidst the Nebulox Seven space debris. The Smuggler notes he can help open it if they find five of the six required keys.
It is recommended to first "win the Gold Cup" on Kragg's Destructapalooza, as this mission becomes far easier with the Treasure Mapper.
Walkthrough[]
Find the 5 keys[]
Several keys are found inside large spherical objects. These must be raised with a bolt crank, which triggers a cutscene revealing the location of a battery bot. The bot must be caught and thrown into the object before it sinks back into the water, releasing the key and 4,000 bolts.
- The first key can be acquired on foot. It is located behind a large rock on the central area's northeastern tip (not the northern island range).
The second key requires the hoverboots.
- A second key is inside a spherical object on the large northeastern island in the central area. Use the hoverboot ramp next to the bolt crank to race to the Smuggler's area, grab the battery bot, and use another series of ramps to return to the island in time.
The remaining three keys require the GrummelNet Jetpack, available after completing "Trade 30 horns for access to the fuel station".
- A third key is found next to a crashed Thugs-4-Less cruiser on a tall plateau behind the large tree in the central area. Beware, as the island is infested with a large number of serathoids and bursting blekkos.
- A fourth key is inside a spherical object south of the Smuggler, in the area where Neftin Prog's hideout is located. The bolt crank for the crane is on a small ledge on the western cliff wall. The battery bot is located on a distant tall tree root in the central area. Fly to it, then use the hoverboot ramps to get back in time.
- The fifth key can be found in the western expanse, reachable only with the Jetpack. It is inside a spherical object on a small island in the far west. Fly to the distant battery bot, then race back with the hoverboots to reach the object in time.
After acquiring all five keys, talk to the Smuggler. He will offer the sixth and final key in exchange for all remaining gargathon horns.
Acquire the remaining Gargathon horns[]
By now, the central, western, and southern areas of the Hagrow Swampland will have been explored. Flying gargathons and prominent fossils are easy to spot, especially from the air. However, submerged gargathons and well-hidden fossils will require a more careful search. Using the Treasure Mapper is recommended at this point.
After collecting all horns, return to the Smuggler to "Trade horns for vault key" and "Open the Vault", freeing the Plumber and acquiring 20,000 bolts. The Plumber will also assign the mission "Give the RYNO plans to the Plumber". Unlocking the vault also grants the bronze trophy "Vault Cracker".
