Could someone please help.

 

I'm looking for an RFID blocking bag for my Superb Hatch (arriving Monday) as I keep my car key in my Snickers Leg pocket during the day.

I've heard stories of the boot opening of the key fob gets pressed and where I work, I don't want that happening at any time of the day. I've looked at this https://www.amazon.co.uk/gp/aw/d/B01KFUBM3S/ref=mp_s_a_1_11?ie=UTF8&qid=1497558590&sr=8-11&pi=AC_SX236_SY340_FMwebp_QL65

 

Would the main key fob for the car fit in this pouch or would I need a bigger one. And if anyone has a ruler/tape, could they let me have the dimensions please.

 

Cheers

 

 

I'm not sure an RFID bag will help as the power level off the key is enough to 'escape'.  You need a bag to contain and fully screen 868MHz keys not RFID which operate in a different way.  Or just don't keep it in a pocket.  I have been trying to find a key cover similar to that used by a number of car makers - and for precisely the same reason - but Škoda just don't do one and the other VAG keys are different.

1. An RFID bag, even if it did block the signal, is not going to prevent the boot release button being pressed and held down, ergo draining the fob battery.

2. The transmitter/receiver in the fob is passive until it receives an interrogation from the car. This occurs when you place your hand on one of the front door handles or press the boot handle to unlock/lock or, if fitted, when using the virtual pedal. This is when the system may be vulnerable to RF interception. As the car needs to communicate with the fob, the key will need to be outside of the bag anyway. Not needing to handle the key is supposed to be part of the convenience of KESSY.

3. Get a decent stiff key case instead, one that won't allow the boot release button to be pressed while it's in your pocket and also won't inhibit the convenience and functionality of the KESSY system.

 

I had the mysterious boot opening syndrome and thanks to recommendations on this forum I, along with many others, ordered one of these and since then I've never had the boot open of it's own accord. And yes, any of the three keys provided fit perfectly inside.

 

Cheers folks

Many thanks for the advice. Admittedly yes, I need the case which BillyJim recommend for during the day. And also the RFID blocker for an evening as my keys are kept (in relation to the driveway) fairly close, so for a few quid extra I'd rather be safe with my new pride and joy. 

 

@BillyJim

Case now ordered. Thanks for the heads up

To my understanding, the RFID in the fob is only for the immobiliser. Referring to the Kessy system here but to me this explains why you can open the car but not start it without the key inside the car and why you can start the car with a dead key fob. RFID is usually passive with a very short range, (think contactless payment cards) so the opening of the boot is not done by RFID. If you are worried about someone scanning the RFID code, if they were successful in replicating it, they still would not be able to unlock the car to my understanding.
