Abstract

Bei einem Verfahren zur Code-Sicherung für einen elektronischen Schlüssel, insbesondere für Kraftfahrzeuge mit eingebauter Zentralverriegelung, sendet ein Sender (1) mit nachgeschaltetem Verstärker (3) über eine Fotodiode (4) ein codiertes Infrarotsignal (5) aus. Dieses Signal (5) wird mit Hilfe eines Fototransistors (6) über einen Verstärker (7) einem Empfänger (2) zugeleitet, an dessen Ausgang (8) ein Signal (9) zur Steuerung der Zentralverriegelung ansteht. Mittels eines Zufallsgenerators, der entweder im Sender (1) oder im Empfänger (2) angeordnet ist, wird aus der Auswahl der Code-Möglichkeiten ein beliebiges Bit-Muster ausge­ wählt und Sender (1) und Empfänger (2), vorzugsweise durch eine Zwangssynchronisation, übermittelt. In a procedure for securing code for one electronic keys, in particular for motor vehicles with built-in central locking, sends a transmitter (1) with downstream amplifier (3) via a photodiode (4) a coded infrared signal (5). This signal (5) is with Using a photo transistor (6) via an amplifier (7) fed to a receiver (2) at its output (8) Signal (9) to control the central locking is present. By means of a random generator, which is either in the transmitter (1) or arranged in the receiver (2), the selection any bit pattern of the code possibilities chooses and transmitter (1) and receiver (2), preferably through a forced synchronization.
