"An odd-shaped key. Umbrella's logo is on the tag..."
In William Birkin's underground lab, there are several white lockers bunched together in the area. One of them has a flashing blue light and is the Weapons Locker.
The key is hidden in the side of the Cable car platform. The Lighter must be used on the mounted flare gun to light up the area, revealing the key's location.
