How to obtain keycode for 6000CD Ford Transit Connect?

Hi,
I drive the company Ford Transit Connect supplied with 6000CD Player. Unfortunatelly they have changed the battery just before I got the van. As the company has many other more important things to deal with my radio is to be useless until next service - scheduled in 10000 miles. I found the User Manual valet in the glove comparment but the code has not been writen down in Audio Guide book. How can I obtain the code, please? I have all the certain numbers such as VIN and so on. I would greatly appreciate any information given. Thank you very much indeed. Daniel
