FIELD: construction.
SUBSTANCE: electronic lock comprises at least one sensor for key entry, a permanent memory for a recorded original key (cliche), an element to compare the entered key with the cliche, an actuating device for opening, a cliche is a sequence of pulses from according sensors of certain length and pauses between them recorded in the permanent memory, has a reference map of sensor contacts sequence, without taking into account duration of the contacts themselves and pauses between them, which does not permit keys that are a priori unsuitable, for final comparison to the cliche, and makes it possible to establish a threshold of total mismatches when the cliche is compared to the key permitted for final comparison.
EFFECT: safe reliability improvement.
