Hello Doug777 and welcome to the BlackBerry Support Community Forums.
Thanks for your question on manually locking your device.
On the Home Screen you should have a gold padlock icon that says Password Lock when highlighted. When you click on this icon it will lock your device and you will need to enter your password to access it.
If you can't find this icon, it's possible it could be hidden. Hit the Menu key and select Show All. The icon will appear grayed out. Highlight the icon and hit the Menu key then select Unhide Icon.
Hope this answers your question.
