I moved into an apartment complex where the key is both unique to each apartment door, but every key can open the front door, how are both possible?

Think of it like a 5 number combination lock. All the apartment keys can open combination 1-2-3–x-x. The front door only requires the first three digits. Your key could be 1-2-3-7-5. So every key starts with 123 allowing them to open the front door.

As far ad im aware, the pins would have 2 positions that open the door. Your key hits your first position, the master key and extra pins are all mathed out so it can fit any door.

The outer doors, are usually simpler locks (fewer pins)
At the apartment complex I rented.. the outer door was a 2 pin lock. The inners where more.
But that allowed every key to open the outer door.
It was also easily picked. And the camera that faces the sun every morning, could barely pick up shapes. But they got to list them as security features.

Others have explained the “how”, I just wanted to add that this is incredibly common.
And I’d be willing to bet the super has a master key that opens all the doors, internal and external, for emergencies.
Our business has “tiered” keys. Some only give access to your own office, supply closet.
Some give access to offices of anyone equivalent or below you (so, managers can cross cover paperwork, and access workspaces for folks they supervise)
And some open every door in the building.
They’re numbered, the lower the number the more you’ve got access to.
