Hi. Is the Dell yours? If it is, a call to Dell will help start the process of unlocking.
They also have a live chat here: http://support.dell.com/support/topics/global.aspx/support/chat/hardware_chat?c=us&l=en&s=gen
You will need to send it to them. It can't be unlocked otherwise. Sorry.
Call them. It's a toll free number.
