Key Codes

[Ezzack Hunt]

Dumb question, but I seem to have max key codes. how do I use the ones I have so enabling me to get more?

Lock boxes or mod caches, found next to almost every vendor. Those chests next to it.

Just spend them on some lock boxes - not much else you can do with them.

Buy the Tier 3 ones. The tier 2's are usually crappy, and Tier 4's take a lot of your keys but usually drop goodies. I've come to find tier 3's are the best...imo. But keys are harder to attain now, so I'd recommend the 3's or even 2's if you're a lower level.
