UIKeyboardAnimationDurationUserInfoKey is a const string identifier for the dictionary key that holds the animation duration, so there is no way to change it easily.

One way to make the keyboard appear without animation is to observe the keyboard notifications and disable animation when it's about to appear and then reenable them. This, of course, disables any other animation as well.

[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(willShowKeyboard:) 
                                             name:UIKeyboardWillShowNotification 
                                           object:nil];

[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(didShowKeyboard:) 
                                             name:UIKeyboardDidShowNotification 
                                           object:nil];

- (void)willShowKeyboard:(NSNotification *)notification {
    [UIView setAnimationsEnabled:NO];
}

- (void)didShowKeyboard:(NSNotification *)notification {
    [UIView setAnimationsEnabled:YES];
}

and then then the same for UIKeyboardWillHideNotification/UIKeyboardDidHideNotification notifications.
