I've had these. They worked for a while. But then I guess the metalized fabric wore through or something, because after a while they no longer kept the car from starting. The smallest ones I could find would actually hold two fobs, but when filled were large and uncomfortable enough in my pocket that I preferred to just keep the fobs naked. I still haven't found a good solution that actually works for keeping passive fobs secure while they are actually in my pocket.
