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?

Your key is a series of numbers (called cuts). When you try to use that key, you test if the lock has the same numbers. You can keep some of those numbers the same for all doors in your building and only test for those on the front door and use the rest for individual apartments.

The front door has less pins in the lock. The key goes in and only the end few cuts on the key are needed. Then when you get to your door the lock has more pins and the key goes in farther and uses more of the cut pattern on the key.

1 half of the key is for the front door, all keys will have it in common. The other half is for individual use.
To add to what others said, some locks also have multiple valid cuts on some pins. Position 1 might allow a 4 or 6. Some more complex multi key systems use this along with complex rules so you might have a manager who has a key to a multiple building with a higher up manager might have a key to even more buildings. It does make it more pickable though.
