Does your handler get fired? Have you wired up the event in the XAML, correctly? `` — Geoff James, Jun 21 '16 at 10:23
Are you sure that you want a Key-Event on a button? This requires that the button is Focused... — lokusking, Jun 21 '16 at 10:27
Usually you do this via InputBindings and commands in WPF, not by intercepting key events and handling them. — Joey, Jun 21 '16 at 10:30

You need to try something similar to this

private void AddHotKeys()
{
        try
        {
            RoutedCommand firstSettings = new RoutedCommand();
            firstSettings.InputGestures.Add(new KeyGesture(Key.A, ModifierKeys.Alt));
            CommandBindings.Add(new CommandBinding(firstSettings , My_first_event_handler));

            RoutedCommand secondSettings = new RoutedCommand();
            secondSettings.InputGestures.Add(new KeyGesture(Key.B, ModifierKeys.Alt));
            CommandBindings.Add(new CommandBinding(secondSettings , My_second_event_handler));
        }
        catch (Exception err)
        {
            //handle exception error
        }
}

Events

private void My_first_event_handler(object sender, ExecutedRoutedEventArgs e) 
{
      //handler code goes here.
      MessageBox.Show("Alt+A key pressed");
}

private void My_second_event_handler(object sender, RoutedEventArgs e) 
{
     //handler code goes here. 
     MessageBox.Show("Alt+B key pressed");
}

If you are following MVVM you could try this reference

<UserControl.InputBindings>
<KeyBinding Modifiers="Control" 
            Key="E" 
            Command="{input:CommandBinding EditCommand}"/>

See the reference

You should be able to do this in your xaml

<Window.InputBindings>
    <KeyBinding Command="{Binding MyCommand}" Key="F2"/>
</Window.InputBindings>

<Button Command="{Binding MyCommand}"/>

MyCommand is an ICommand implemented in your windows' / view's viewmodel.

So both the button and the F2 inputbinding will execute the same command.
