your if statement is wrong

PHP Code:

if (e.KeyCode == Keys.F5)
{
    if (!timer1.Enabled)
    {
        timer1.Start();
    } else {
        timer1.Stop();
    }
}

private void MainForm_KeyUp(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.F6)
                timer1.Enabled = !timer1.Enabled;
        }
