Abstract
The electronic lock can have a housing having a wall portion being flat, and a keypad. The keypad can have a sequence of characters aligned along an axis parallel to the wall portion, defined by corresponding translucent areas extending across the thickness of the wall portion; a set of touch sensors underlying corresponding ones of the characters of the sequence; a light guide underlying the wall portion, the light guide being flat, parallel to the wall portion, and having a thickness, the light guide being optically coupled to the translucent areas via the internal face; and a light source offset from the plurality of characters, operable to propagate light into an edge surface of the light guide, for the light to propagate within the light guide in a direction of the axis.
