Kept the secret
Locked lips describes a state of determined silence—refusing to reveal information or secrets.
Someone with locked lips won't talk no matter how much they're pressed: She kept her lips locked about the surprise party.
The phrase evokes a mouth sealed shut as if by a lock, emphasizing the deliberate, protective nature of the silence.
