Cell Key

The Cell Key is a quest item found in Pathologic. It is obtained in the Bachelor's route on Day 5 and is needed to free the Haruspex as part of the main quest "Vaccine".

The Bachelor will find the Haruspex imprisoned in one of the empty factories in the Works and several patrolmen guarding him. After getting rid of the guards - either by taking them on himself or seeking help from Bad Grief - the Bachelor will find the Cell Key on one of their bodies, which he can then use to open the cell door and free the Haruspex.
