lets in

Opens the door

Lets in means to allow entry.

You let someone in by opening a door, or let in light by opening curtains.

The phrase extends to admitting abstract things: Don't let doubt in.

To let someone in on something is to share secret or privileged information: Let me in on what's happening.
