Your're living in a building.
The building has a main door, and each household in the building has a same key to get through that door.
One day, you forgot to bring the key.
Is it correct to say "we have to wait for someone to get in so that we can have a free entry" or "we have to wait for someone to get in so that we can have a chance to get in" (but we repeat "get in" twice)
