VONETTI Alpha Shield-V2 9cm - Premium Keyless Car Key Signal Blocker Box- Aluminium Faraday Bag for Car Keys – RFID signal blocking faraday pouch – safe metal tin - anti theft cage

This box is undoubtedly a "quality" item. - It can be seen immediately that it has been precision manufactured, and it has a very pleasant and tactile feel in the hand.As for function, it does what it sets out to do - 100% effectively.Upon receipt, I tried multiple times to gain access to my vehicle with the key-fob in the box - at every distance from several metres away, to practically touching the car. No success! - The car just doesn't recognise the key-fob when it's in the box!Therefore, I'm as convinced as I can be that no signals which would enable unauthorised access to my vehicle would be getting out of the box.My only criticisms are: -1). At 101 grams, it is rather heavy, and with its overall size, it is noticeably bulky when carried in a trouser pocket. But - used for all those times when the fob is in the house, I cannot think of anything which would give better signal protection.2). (For my particular and rather slim key-fob). - Whilst the height suits my fob perfectly, the width and depth of the box leave quite a lot of empty space, and the fob can effectively "rattle around" inside. (Although it must be said that the box is well lined with soft suede-like material).However, I appreciate that it has to be sized to fit the majority of vehicle manufacturers key-fobs, so precise fit for any given fob will be a matter of pot-luck.Overall, on the expensive side, - but as the saying goes, "You get what you pay for", and this box is a masterpiece of precision metal engineering!

I previously bought a similar metal key signal blocker from another brand here on Amazon. This one is more curved and thinner (but taller). It gets the job done, blocking any signal between key and car. Unfortunately, the problem is the fitment. My Audi key fits in perfectly snug, that's not the problem. The case itself fits very tight together; there is quite a bit of suction so you do need to use considerable force to open it (at least for what it is).The problem is sticking the halves back together. Because the fitment is so precise, I can't put them together unless I match them nearly perfectly straight. Sometimes I might need 3 tries. The edges are slightly curved but it just needs more work.Naturally, I'd expect some resistance holding the thing together but it's just far too tight here. I have another similar one so I do know what I'm talking about when I say this. The other one literally glides in without fitment issue. It seems like a minor issue, but I drive my car daily so I'm having to use this daily. It certainly looks premium but touching it isn't something I fancy. More tolerances are needed...

Only had this a few days and am really pleased with it.As a lot of reviews state, it is a bit tricky to open and close because of the tolerances of the join but with practice I can now do it one-handed.Like others have said I can stand right next to the doors with the key inside and the car stays locked.If I could suggest an improvement it would be to have a larger size so I could get more than just the key inside.I've previously used the pouch types but they don't last. If you use those I would suggest you check they still work at least every week.This looks like it will last for ever and will pay for itself in no time at all.Highly recommended.

A really well made product that definitely blocks the keyless signals. What’s handy is you can leave the key in the case, simply without the lid on while in the car and it recognises it.A couple of things i don’t really like:- you can’t easily take the top off with one hand.- when you do take the lid off, you have a loose lid which is annoying if you’re carrying anything.- the lid is hard to get off, even with 2 hands. I’m assuming this is because of a slight airlock? Would a tiny hold work?I know Vonetti makes the businessman option however i decided on this V2 version over that because it was more rounded (comfortable in the pocket) and it was also less bulky.The businessman one was very convenient as the lid came off (answering the comments above). I think the businessman one would be improved by:- having a deeper lid (so that there is more of the key exposed while open - in the car).- make it so that the lid fold all the way back with some more magnets so it remains open while sitting in the car.Overall I would recommend this product. I’m happy with the product as it performs exactly as it should (unlike little pouches). It is very well built and a premium product.

The idea is fantastic and it works on my key at blocking the keyless entry signal. I like it’s rounded form factor too. However it’s very bulky and large. I feel this product should be sold in two sizes. It’s very long at 9cm. My car key looks lost in it, as it’s only 6cm long, pain to take out too.I feel a slimmer and shorter version should be sold for those with smaller keys and a spring loaded base to pop your key out when required.Also this is very difficult to open, especially when your out and about or on a cold day in the winter and you have gloves on or not.I like their idea of the flip case version with magnet clasp but that version doesn’t work at blocking the car key signals. Such a shame

Blocks the key signal and I’ve managed to fit a 2017 Audi Secure Key fob with one key ring and an RAC Key fob in it which is 2.5mm thick, side by side with the secure fob into the box and it still rattles about so plenty of room for this type of secure fob, I’ve included pictures to illustrate. The car can’t pick up the signal when you put the box next to the emergency key receptacle on the steering column either. Top marks.

This is a precision product that works perfectly.I bought it to replace a soft faraday key pouch that was rubbish (I could still open and start my car when it was in the case)With this product the key fits perfectly and no signal escapes. It looks smart too.I would highly recommend this item.
