Outstanding!
With all of the hype over keyless cars being a security risk, they are a real comfort. Just bought a new keyless Volvo so we felt quite vulnerable. I tested the pouch by sitting inside the car and it blocked 100%. Also big enough to take a mobile and tested by buddying next to my wife’s mobile and it totally blocked the connection. Great product.

Large enough for 2
Capacious enough for 2 keys if required. Works just as it should.

Update: failed after 3/4 year. Orginal: Does the job but wish it were a tad smaller
Update: Failed after 3/4 of a year. I can now lock and unlock the car with the fob in the closed pouch. If signals can get out that a scanner can surely get in. OK, this thing was in my thigh cargo pocket 24/7 but I didn't particularly mistreat it. Can only imagine the faraday lining just wear out or something as this is the second pouch I've owned (two different brands) that's failed after less than a year. I had a smaller pouch before this one which lasted only a few months before it failed and I could open and lock the car with my fob inside that pouch. Poor show, even though it was relatively cheap. So I thought I'd try this new one instead and see how I get on. It's three times the size of my previous one but so far, seems to be doing the job and I test it weekly to make sure it is. I sort of have to push my key fob to the bottom and then fold/roll the excess around so it fits in my cargo trouser/short thigh pocket. This is only because I insist on carrying my fob around everywhere, but this is obvs not a problem if you intend to keep it in a handbag or have it lying around. My only gripe is I wish it were smaller and the approx. size of the keyfob but perhaps that's why my previous one failed -- it was too small and got ruined. As I say, so far so good. If anything changes, I'll come back and update this review.

Security car key / phone pouch
Good product. Bigger than I thought and the pouch takes car fob and house keys. Got two pouches so one for the spare car key as well. I would recommend.
