Abstract
For unlocking a functionality of a computer controlled apparatus, an identification code is obtained and sent to an unlocking service. An unlocking key including a functionality code that represents at least one functionality to be unlocked is received and a combination of the unlocking key and the identification is checked against a predetermined requirement. If the checked combination meets the predetermined requirement, the functionality represented by the functionality code is unlocked. The unlocking has a limited validity ending after the first unlocking of the functionality in response to the checked combination. An apparatus for carrying out such a method and a method for providing an unlocking key therefore are also described.
