The contents of a keyboard definition file depend on the software that created it. It may define a keyboard layout or store customized controls, shortcuts, key bindings, and other keyboard-related configuration data.
SmartWare and the Windows versions of Delta Force and Diablo II use files of this type for application or game settings. These files are software-specific rather than a single universal keyboard format, so a file created for one program is not normally usable by another.
The associated software generally reads the file from the location it expects when it starts. Its usability therefore depends on having the original program and, where relevant, a compatible version of that program.
On Microsoft Windows, open the file with the software that created it: SmartWare, Delta Force, or Diablo II. These files are normally loaded automatically when placed in the program's expected folder rather than opened as documents.
A generic text editor or another application is unlikely to interpret the settings correctly.
These software-specific keyboard definition files are unlikely to be convertible to another format. If another program uses a different configuration format, recreate the keyboard layout or key bindings in that program.

The key file extension is used in Windows 7 much like REG format in previous versions of Windows. It is a file that contains registry information.
You can simply add the registry entry with double clicking on the .key file. You can also view and read the content in any text editor.
Be careful when handling registry file, they might contain malicious code or otherwise corrupt your computer. Always be sure to install registry entries from reliable sources.
Opening the file in windows results in the registry data being added Windows. A *.key file can also be viewed/edited using in any text editor.
Although you can technically "convert" key registers much like any other text file, there is practically no reason to do it, as such conversions would be pointless.
