Digital electronic key and lock system

A digital key and lock system for enabling access to at least one protected domain in response to an enabling signal, comprising:

• key means having at least one key cam configured for representing a digital key code composed of at least zero and one bits marked in line on said key cam;
• an electronic device having means for receiving the digital key code, code-containing means for containing at least one further digital code, code-comparing means connected to said means for receiving the digital key code and to said code-containing means, said code comparing means operative for generating the enabling signal when said digital key code is equal to said further digital code;
• at least one key lock having a key inlet adapted to receive the key, and a digital code reader connected to the key lock being operative for reading the digital key code;
• and electronic gating means coupled to said digital code reader for deriving from said digital key code steering pulses for steering said digital key code into said key code receiving means.
