I got a quote of about $200 plus CAD. The valet (non-electronic) key was not much cheaper.
So it would probably be the same here, with the current value of our dollar. I will have to call the dealership tomorrow and see if I can't get a quote over the phone, they're 90 miles away - not too convenient to just stop in for an estimate. Has anybody else had a hard time opening up the key and changing out the lithium battery? I found it strangely difficult...there's a little plastic bracket that popped out when I opened it, and the original battery looked corroded/burned...it was hell trying to fit that bracket back in with the new battery. I don't even know if I did it right or not. Is this probably just a user error, or do you guys think it might be shot?
