Utility worker ID

The utility worker ID is a miscellaneous item in Fallout 3.

Characteristics
If the protectron in the Old Olney sewers is activated it will go on patrol and will ask you for proper I.D. if you come close enough to it. Once scanned it will remove the utility worker ID from your inventory, but will not become hostile.

Locations
The ID card is found next to a skeleton in the Old Olney sewers in the same room as the maintenance protectron.
