Abstract
Method for accessing a user operable device having a limited access ability by a user. Therefore a user transmits an inquiry using a mobile device via a wide area transmission network to a key authority. The key authority retransmits an electronic access key. This access key is stored in the mobile device and later transmitted to a controller unit controlling the access the user operable device allowing the user to operate on it.
