Just keep your keyfob in a metal box when its in the house.  This blocks the radio signal and the theft can't work.

What a good idea. Will the microwave do it?

Seems the BBC are a bit short on news today, as this has been in the news for the last 6 months or more.
I have keyless entry/start on my car, and for a couple of quid I bought a small RF protection pouch from Amazon, and just pop my key in it when indoors.

It's actually a very similar problem to the contactless credit/debit card cloning scam, and uses a similar method to clone, that's why I also have an RF blocking wallet.

Totally agree, given the price as you say. However manufacturers are probably working on a more secure system for the future, maybe using an encrypted signal.

Surely these are already using an encrypted signal. The problem is using relays to extend the range of the key which will still work if the signal is encrypted. I have read comments online today saying that these keys can be switched off but many owners don't bother to read the instructions to find out how to do it.

just how does that defeat the immobiliser or the steering lock....  or don't we get immobilisers anymore? 

What is needed is a way to disable the remote locking so you can lock the car with the key when you leave it overnight and only use the rf keyfob for convenience when out and about, trouble is..the RF receiver is buried somewhere in the car wiring loom and I just can't find it.

Why not just fit the key with an on/off switch?

I have seen on the tv ( so it must be true :D ) they plug into the diagnostic plug, and recode it, :co then drive it off,
anyway the car manufactures don't give a dam, they are sold aboard or in pieces so it only boosts their sales,,,  :banghead:

Not quite - what they do is programme a new key.  In the case of Mercedes - and several other manufacturers - the key is just a carrier for a radio code chip; there is no physical key that has to be cut to match the tumblers of the ignition lock.

In order to get into the car to access the diagnostic port, they need the radio signature of the key, so they have a box that simulates the car asking "WHO ARE YOU" and then capture the key's response and play it back to the car.

A friend has his nearly new BMW stolen earlier this year - he thinks that his local car valeting firm copied his physical key whilst cleaning it, and then tracked down where he lives to steal the car.

Yes that sounds right, if one day I was out of my mind enough to buy a BMW, :-\ I would wish that
they would steal it, have you the addressee of the car wash ?.
