Test report: 2011 Volvo C70 all keys lost success using Autel IM608 and XP400. First one I have done. Got through it nice and smooth. The 5-button Fobik key i got from ebay. It can be used on 2006-2013 Volvo C70 (aslo some C30, S40, V50). You have to remove CEM module and save 2 files from CEM. Solder work. Remote control is working as well.
