This locked chest is the fourth of El Este's four Criptograma Chests, hidden in the La Joya area. Find its two Criptograma Charts and it opens to give you a piece of unique gear.
Go to the People's Pride Clinic in the Dorada Cove area of La Joya and get up on the roof. The chest is up there.
The chest stays locked until you have both of its charts. Look for Guerrilla Sigils, the guerrilla markings painted near the chest, and follow them to each Criptograma Chart. Once you have both charts, go back to the chest and open it.
Inside is the Hazmat Pants MK II. The two charts you used are also added to your Criptograma Charts collection, so every chest you open moves both lists forward.
