    Have tried this out and it blocks the fob's signal fine. I've also found that it's better to remove any existing key ring/tag and use the supplied ring in the pouch.

    A well made product and quick delivery from a professional company. The Mini pouch arriving just before Christmas. (Thank you) The car keys only just fitted inside though - was a bit tight, so the pouch could be a couple of millimetres bigger. Would buy again from this company.
