How to unlock the The Key Master achievement in Resident Evil - Definitive Guide
Read the forum post here: 3 achievements not unlocking (solved)
The spoiler makes it so you don't even need to actually fight the boss.
V-Jolt Method
How to Get to Plant 42
Once Barry, if you did the steps in the tags above, kills the plant, the key is in the back of the room.
I didn't fight the plant, as I did the V-Jolt method, but if you choose not to, use Flame Rounds for the Grenade Launchet on the plants body, they do the most damage and should take it out in 3-4 direct hits, then again after it regrows in 2-3 direct hits.
If you're going to downvote, let me know, out I'll just spam you with updates about this achievement.
Back to the basement, trolls. lol
This is a Jill only storyline trophy. To earn this trophy you must defeat Plant 42 as Jill and then obtain the Helmet Key in its room. This fight happens in the Residence and can be completed either through firepower or use of the V-Jolt. You’ll earn this trophy once the boss is dead and you have the key.
See Boss Data for additional details.
This is obtained at the end of the Residence area, after Plant 42 is defeated. See "Herbicide" for details on creating V-Jolt and how to eliminate the plant. As Jill, you do not have to fight it at all as Barry will finish it off with a flamethrower. Pick up the key from the fireplace and the achievement should unlock.
