How to unlock if the Global Administrator is locked?

If you can get to access the database, you can modify the administrator record in the CMS_User table.

Method 1:

Using below query to unlock Global Administrator from Database:

 UPDATE CMS_User set UserEnabled=1 WHERE UserID=<userid>

Method 2:

you can also use the CMSAdminEmergencyReset key in your web.config file.
Reseting the password via a web.config key can be done by inserting the following key to the appSettings section of your web.config:

<add key="CMSAdminEmergencyReset" value="<your username>;<your new password>;[true/false]"/> 

The first and second parameter specify your user name and your new password, delimited by a semicolon. The third parameter is optional and indicates whether you want to create a new user with global administrator rights.

The appsetting key will be automatically removed from web.config after you got access to the CMSDesk or CMSSiteManager.
