keypress simulator for testcomplete web

I'm trying to emulate the following simple step:

  panel = frame.frameIpsframe.panelMain;

  passwordBox = panel.passwordboxInputpin;

  passwordBox.SetText("zzzz");

But the "zzzz" is in real recorded from the keypress and xored with a salt. nothing whats in the box.

I've tried both LLPlayer.KeyDown/KeyUp and SysDesktop.KeyDown/KeyUp

I like to enter "1111" pin into the webpage but nothing works, I try with mouseclick and hover to make sure things are entered at the correct place, but nothing arrives in the box

  passwordBox.Click(43, 13);
  passwordBox.HoverMouse(45, 13);

  LLPlayer.KeyDown(1, 2000);
  LLPlayer.KeyUp(1, 2000);
  LLPlayer.KeyDown(1, 2000);
  LLPlayer.KeyUp(1, 2000);
  LLPlayer.KeyDown(1, 2000);
  LLPlayer.KeyUp(1, 2000);
  LLPlayer.KeyDown(1, 2000);
  LLPlayer.KeyUp(1, 2000);
  //Sys.Desktop.KeyDown(1);
  //Sys.Desktop.KeyUp(1);
  //Sys.Desktop.KeyDown(1);
  //Sys.Desktop.KeyUp(1);
  //Sys.Desktop.KeyDown(1);
  //Sys.Desktop.KeyUp(1);
  //Sys.Desktop.KeyDown(1);
  //Sys.Desktop.KeyUp(1);   
  //passwordBox.SetText("1111");

Thanks Any ideas very appreciated.
