Quit. Developers need full access to their machines or they are stifled. This organisation is not interested in you doing quality work. Your options are therefore to either resign yourself to not doing quality work, or leave that organisation, ideally making sure that management knows exactly why you're going. (Of course, the chance of management actually caring is about one in thirty seven trillion - if they cared about quality of work or employee satisfaction, your machine wouldn't be locked down. So not bothering to tell them is fine too. Tell them if you're feeling charitable)
