I use a Faraday pouch and can confirm it works perfectly.
Me too and I've tried to open the door with it right next to the door and with the pouch actually opened so the signal must be directional from the key.I use a Faraday pouch and can confirm it works perfectly.
I knew there was a very good reason but I just couldn't think of it! yes if the fob battery ran out whilst driving it'd be very bad if it just cut the power!What @JodyS21 is saying is once the thief has picked up and copied the key signal, he can use his copying device as you would the key. He can open the car by putting his device next to the door, then he can start the car by taking his device inside the car. It's not difficult to pick up the key sign, even if it's further away than the car can pick it up, they just use a bigger antenna and a signal booster. It's always best to block the signal with a Faraday pouch rather than rely on the key being further away.
FYI, you can drive off without the key once the car is started. This is a safety feature to prevent the car shutting down (e.g. stopping in the middle of the road) if the fob battery expires while you're driving.
Very bad in the 3rd lane of a motorway and when the car powers off the parking brake comes on ?I knew there was a very good reason but I just couldn't think of it! yes if the fob battery ran out whilst driving it'd be very bad if it just cut the power!
It's part of the reason for the price of the service, they change the fob battery lolOh my, you're right! Checked it and guess what... So my apologies, didn't know that untill now. Been told it had no battery so didn't bother to check that myself. Well, never trust a dealers salesmen I guess.
Mmm....is that a "fact"Oh my, you're right! Checked it and guess what... So my apologies, didn't know that untill now. Been told it had no battery so didn't bother to check that myself. Well, never trust a dealers salesmen I guess.
It only goes some way to show what we already know, that some sales people have absolutely NO idea ?Oh my, you're right! Checked it and guess what... So my apologies, didn't know that untill now.

It could work like an RFID chip does...It only goes some way to show what we already know, that some sales people have absolutely NO idea ?.
If the fob had no battery, I fail to understand how the circuit board contained in the fob, would get the power to send a signal to the car ??????.
Unless you wanted to manually open the car with blade contained in the fob of course ?.
Yep !.It could work like an RFID chip does...
The car sends out wireless power via a coil...that gets picked up by a smaller coil inside the fob and then you can power the circuits inside the fob to send a message to the car....
But it doesn't work like that...it's just a battery ?
They call it NFC ('Near Field Communication'). The fact that the key is passive and can be only operated in very close proximity of the door locks makes it secure. A miscreant would need physical access to the card.The Tesla key card works like a contactless payment just bring it near the b piller to unlock and place in centre console to enable driving.
Hi we just got our car back from the garage with a list of fault. One was the rear tailgate remains open after you have locked the car. We tested it and you have to be over 50m away before it remained locked so be carefulThe way to prevent these remote extension devices is to keep your keys in a screened container. A metal box or faraday cage bag will work fine. However, having experience of other cars with this type of access I can advise that with the MG system the key has to be VERY close to the car to work anyway, which is good. Try it for yourself…….
I think though that the battery is there for sending a signal to open or close the door when a fob button is pressed. The car sends out a rfid signal to the RFID chip on the fob on which it receives a return signal if the fob is nearby and then releases the locks and alarm. Otherwise how would it work with unlocking and locking the doors with the doorknob and the key s in your pocket without touching it?Yep !.
Flat coin cell ? battery - keep it simple.
