This locked chest is the second of El Este's four Criptograma Chests, hidden in the Conuco area. Find its two Criptograma Charts and it opens to give you a piece of unique gear.
Head to Conuco in El Este and slow down once you are close. Criptograma Chests sit near guerrilla paths or in other tucked-away spots rather than out on the road. The sound of wind chimes is your best clue that the chest is nearby.
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 a piece of unique gear. The two charts you used are also added to your Criptograma Charts collection, so every chest you open moves both lists forward.

Criptograma Charts are the coded symbol sheets that open Criptograma Chests. Every chest needs two of its own, so you hunt down 30 charts in all to empty the 15 chests on Yara.
