If the removal is in a function and the key needs to be a variable, try this :

removekey = (keyname) => {
    let newState = this.state;
    delete newState[keyname];
    this.setState(newState)
    // do not wrap the newState in additional curly braces  
}

this.removekey('thekey');

Almost the same as steve's answer, but in a function.
