Electronic key system for e.g. opening door of motor vehicle, has microprocessor programmed to select to-be-activated function and associate selected function to signal for permitting recognition of function and for activating function

摘要

The system has a signal receiving element (2) associated to a microprocessor (6) to process a signal for identifying a function to be activated in a motor vehicle (V). The microprocessor has a storing unit for preliminarily storing a set of preset functions. The microprocessor is programmed to select the to-be-activated function from the set of functions and associate the selected function to the signal for permitting recognition of the function during emission of the signal by a programmable emitter element (1) and for activating the function. The emitter element is in the form of a remote control having a key and an LCD screen.
