Rogue Galaxy - Sun Key

Sun Key

The Sun Key is located in the Chief's Hut on Rosa in Johannesburg. Right after you watch the cutscene with him after arriving here you can grab the key from the chest next to you. This one is actually really hard to miss as it almost literally puts the chest on your screen after the cutscene. This is the last of the keys you'll have to obtain in Rogue Galaxy and it requires all previous keys to open the chest. Congrats you're done!
