Keyless access (called comfort access by some) is actually a terrible security weakness. It's well-known that you can get 'boosters', meaning that the ne'er-do-wells can boost up the signal from the remote (sitting inside your house), to open the car that's parked on your drive, then get in and drive off in it. And all they have to do is switch on the booster, then open the door, get in and press the 'start' button. Car gone.
I'm told it can be nullified if you keep the key in a faraday cage.
Not a 'feature' I'm keen on, myself.
I didn't know that, nor had it occurred to me, although I was not under the illusion that it is theft-proof. Thanks.
The Faraday shield should not have holes unless they are significantly smaller than the wavelength. I reckon the wavelength range is 0.7 - 0.9m so any fine mesh should do, but I think I'll pop mine in an Oxo tin at home. I wouldn't trust pig wire even if the theory works!
I don't mind keyless, I am less likely to lose the key which I can keep in a zipped pocket, and it's more convenient for loading when my hands are full. Not really necessary though.
