By killing Zryachiy you will fail and lose access to this quest.
*Not all spawn locations for the quest item require this key. It is not entirely needed to complete the quest.
There are multiple spawns for the V3 flash drive at the water treatment plant on Lighthouse. After obtaining it, you have to reflash the transmitter at the Intelligence Center level 2 in the Hideout. Electricity is required during the entire process, otherwise it will be interrupted. After the reflashing is done, the transmitter is fully functional and can be used to bypass the Claymores and Zryachiy guarding the bridge to the lighthouse peninsula, allowing you to visit the lighthouse building and meet Lightkeeper.
Note: If not all members of your lobby-made group have an encoded transmitter, it will have the "blocked" state and the bridge can't be passed.
