Only defective SIKs are exchanged.
If options were enabled on the defective SIK, you will receive the code numbers to enable these
on your new SIK after giving us the number of your defective SIK.
The SIK number is displayed on the screen after you have entered the SIK code number. The
SIK number is also printed on the ID label applied onto the board of the SIK.
