FOAMO blocking pouch: open with a car key on the left, closed on the right

Blocking pouch for car keys and cards

Pack of 2

FOAMO RFID blocking pouches interrupt the radio signal of a keyless entry key while it is inside the pouch, so the key cannot be reached unnoticed by a signal relay attack. The pouches fit most common car keys and come as a pack of two – in carbon look with coloured stitching or in durable Oxford fabric. Tip: test the effect once on your own car.

Test it yourself

Put the key in the blocking pouch, close it completely and walk to your car. If the door no longer opens via the door handle, the shielding works.

Repeat the test from time to time. Shielding material can wear with frequent use.

Please note: our key covers do not block radio signals, which is why keyless keeps working inside them. For protection against relay attacks, use a blocking pouch.
