I had asked my service team to look at this yesterday as they didn't know about it either, haven't heard back. I suspect, they made some updates to the profile that where some of the concerns... If it's a completely "free" key then you should be able to be in the care key profile and switch to another profile, as well as not force the key key to be paired to any profile. Can someone how has had this done confirm that functionality?
As for a refund for a purchased key, that is something you would have to take up with Volvo. The dealer sold you a key to fix Volvos issue. Dealers should not be the ones losing here, that's no more morally right than you having to have bought the key in the first place. IMO Volvo is heading towards some rocky roads with dealerships. I just did training that to fix their problem with cars needing updated before delivery they now expect sales folks to be able to do the CPS install. Nothing says luxury car experience than having sales folks under the hood before delivery, and gosh forbid if the software fails and now we're taking the back of your car apart in front of you.
