Radiofrequency electromagnetic radiation-shielding smart-key holder and methods thereof

An electromagnetic radiation (“EMR”)-shielding smart-key holder, comprising:

• a multilayered body having a first face and a second face;
• a cavity within the body sized to hold one or more smart keys;
• an EMR-shielding layer lining the cavity;
• a flap extending from the body configured to fold over the cavity and fasten with the second face of the body,
• wherein the EMR-shielding layer extends from the cavity into the flap such that a portion of the EMR-shielding layer is also configured to fold over the cavity;
• and
• a two-piece touch fastener in which a first piece of the touch fastener is incorporated into the second face of the body and a second piece of the touch fastener is incorporated into a separate, surface-adherable piece of the EMR-shielding smart-key holder.

A method of an electromagnetic radiation (“EMR”)-shielding smart-key holder, comprising:

• adhering a second face of a second, surface-adherable piece of the EMR-shielding smart-key holder to a surface of an object leaving a first face of the second piece exposed,
• wherein the first face of the second piece includes a second set of touch-fastener features;
• placing one or more smart keys into an EMR-shielded cavity within a multilayered body of a first piece of the EMR-shielding smart-key holder,
• wherein a second face of the first piece includes a first set of touch-fastener features complementary to the second set of touch-fastener features;
• fastening the first and second pieces of the EMR-shielding smart-key holder together by way of the complementary touch-fastener features, thereby attaching the first piece to the surface of the object;
• and
• shielding the one or more smart keys from at least radiofrequency communications in place on the surface of the object.
