Pretty much. You need the Tech II scanner. Their new scanner is basically a significant outlay and subscription based and requires internet access and for occasional use you might pay $70.00 for 3 days of use unless ypu have a monthly subscription.

Furthermore, security stuff is further restricted. Two different anti-theft mechanisms are used, One where you need a PIN to make the radio work after power is removed. This mode is optional. The second is the VIN thing.

The radio is also the interface for the consumer to program options in the car like locking, headlights, oil life etc.

I don't know if an automotive locksmith would be cheaper.
