It seems ridiculous that the manufacturers of the most expensive models have "improved" car keys so much that they can be sidetracked at will...and very quickly too.
When car keys developed soo that they had a transponder inside and had to be physically "clicked in" to the car before they could be started car crime plummeted because no key=no start and the only way to steal them was to steal the key.
Now (regardless of the evidence) car makers force keyless systems on us and we might as well secure yhem with a piece of damp string...
I agree with Tomandbobby - a locking device that covers the whole wheel is the safest way to go, awkward heavy and clumsy but think of the benefit of carrying your keyless card in your wallet!
Talk about going back to the 1970's
