Chaper 6 key?

[Galeritis]

Hi there im in the chapter 6, the hunt.
Near the begging, at post office, there is a little house where i need a key to open the main door. Anyone knows where is the key? i didnt find it in guides on internet.

Just explore, you'll find it eventually.
Remember the presence in the safe house mentioning something about that house.

Its found on the body of a mobius operative. I cant remember exactly where the body is but i know it is near pile of corpses which turn into those big sawblade enemies so watch out.

Progress through the zone and inspect all Communicator signals you find...

If you really can't find it:
When you are inside the Post Office there is a dead soldier there (In front of the safehouse door) his residual memory tells you his partner went for supplies in the APC and she has the key to the shack but hasn't returned yet. Later in that zone you'll find a GPS signal that leads you to the partner and the APC she'll have the key.
