@all: These Display keys can be programmed like any other aftermarket key, they don't require special tools. There are sellers on this forum offering newer style keys for our F10, their equipment can also set up these keys. If you talk to a locksmith, please don't confuse them with talking about a highly sophisticated special key, since the programming is a standard operation. I will provide DIY instructions on the CAS4 removal process, then it's just dropping off or shipping this unit with one original key.
So, just contact a locksmith providing key duplicates or upgrade keys, they can program this key as well.
The display and its information are not programmed, the separate information module will deliver the data, so the key shows mileage, fuel range, alarm status, etc. without programming. In order to open/close/start your car, a professional needs to program the display car to your car, by using the CAS4 unit and your original key, since every car is defined by the CAS4 and its specific keys. If not, everyone could just copy your key and steal your car. So the programming is just about accessing and starting the car, the other functions will work right away, everything is included in the key set!
