How to disable WM 6.5 display lock / use the S2U2 (Slide 2 Unlock 2) lock instead

There is a nice replacement for the default Windows Mobile 6.5 display lock: S2U2 (Slide 2 Unlock 2) available at: http://s2v.ac-s2.com/
Unfortunately, after installing S2U2 on my HTC Touch 2, both locks locked the display. In order to disable the WM 6.5 lock add the registry entry

“HKEY_CURRENT_USER\ControlPanel\Keybd\DeviceLockWhenSuspend”

as DWORD and set it to “0”. After a softreset I was able to lock the device with S2U2 by pressing the power/decline-button. Windows did not lock the device any more.
