Afterwards, you will have to go to the derelict mission you want and locate the vault, open it with the dragon key, get the artifact, finish the mission and see what mod was the artifact you got. Once equipped, it will apply a debuf on your warframe (depending on the type of key). For much more detailed information, check the link posted by Ninja above ) Keep in mind that as soon as you pick the artifact from the vault, all remaining enemies change to corrupted units. For solo, you could just find the vault and if it does not fit the key, abort and retry.

Now, you will have to equip the crafted dragon key (as you equip codex scanner and energy restores). These blueprints are purchasable from the clan dojo tenno lab but this time, you will need void traces to craft them (10 each).

Now for the mods, you will have to craft a dragon key. Once you have the key, the relevant node on the start chart will be unlocked and you can play it once. It is now located on the final Assassinate node of Deimos, Exequias Previously (pre Update 28.3 - Derelict Shift), this was called Derelict Emissary Assassinate, and required a crafted Derelict Key for entry. The blueprints are purchasable from the market. Before Update 29 - Heart of Deimos, the Zealoid Prelate previously was in the Derelict zone. You will need nav coordinates (dropped from containers throughout the star chart) to craft the derelict keys.
