Simple idea that seemed effective at first however, the gold foil tape being added started to reflect the RF signal from the key fobs even after adding a rubber insulating barrier on the inside. Layers of just heavy-duty aluminum foil seem to do the best job so far for blocking the RF frequency range used by the fobs.Made a faraday cage to store all of our vehicle key fobs. Simple yet very effective:
- Fido glass 0.5L hermetic jar (gasket removed);
- Two layers of heavy duty aluminum foil applied to the inside and outside; and
- Reflect-A Gold tape applied to the inside and outside to keep the aluminum foil layers in place and more obviously to keep temps in check.
