The system has a portable data medium containing an identification code and an arrangement for receiving and outputting wireless signals. There is at least one antenna near the door for exchanging radio signals with the data medium, a processor connected to the antenna, devices for locking and unlocking the door and sensors which detect the opening and closing functions. The processor unlocks and opens the lock on detecting an opening function. An Independent claim is also included for a method of actuating a door lock without keys.
