Key to the Tower

 is a Quest in Escape from Tarkov.

Dialogue
"I have good news and bad news, which one should I start with? I'll start with the good news! We've proved our potential. Lightkeeper is pleased with us, and wants to meet you in person... Yes, you specifically. The bad news is you can't get to him that easily, the place is rigged with land mines. Plus, a sniper shoots everyone who comes near the lighthouse. We must somehow let them know that it's you, among all the other PMCs that are sniffing around there. So we'll put together a transponder for you. He will pick up the signal, give a sign to the sniper, and disable the mines. The path will be safe. I've already written down what materials I need to assemble it. Finding the transmitter box won't be easy, but I think you could try looking somewhere where the USECs settled down."
