I suspect that what you're seeing is only a 'placeholder' in the LiveSafe UI, and True Key isn't installed.
There are 2 ways to tell if True Key is installed:
1) if it's the full version of True Key, then it will be listed in Control Panel's Programs and Features under "Intel Security True Key". To remove, click Uninstall
2) if it's the "Extension First" (extension-only), then the plugin will be in one of your web browsers, probably the one you use most often, under the browser's extensions settings menu (or "Add-ons" or "plugins", depending on the browser). To remove, select Remove, or click the trash can (depending on your browser).
