Abstract
Multi-code universal electronic key characterized by containing a large quantity of different codes, which for opening each lock only uses one part of the codes. It is used with locks that allow the exchange of codes between key and lock, achieving a high degree of security in identifying the key without giving rise to ascertaining the codes used in other similar locks. Incorporates security devices for preventing analysis of the key.
