It is presented a method performed in a key device for authenticating a user for access to a physical space. The method comprises the steps of: detecting the presence of a lock device; sending a request for authorisation data to an access control server, the request comprising an identifier of the key device; receiving authorisation data from the access control server; determining whether the key device is authorised to open the lock device; and sending an unlock signal to the lock device when the key device is allowed to open the lock device. |
