FOB keys and theft
Keep those in a faraday bag or case when not in use. New vehicles only need the key close to the car, then when FOB is close the door will open and the push-button start will crank the engine and unlo...

so, before the advent of RFID chips and key fobs stealing a car was a simple hot wire job, didn't take much skill.
I decided to see what REALLY happens if someone somehow did intercept my fob and started the car. Used the fob to start the car (which requires the car to be locked). Then assumed said person also was able to unlock the car.
Then I went out to the car in the garage, hung the fob on the wall about 18 inches away from the drivers door, got in and hit the start button (required to actually drive the car). Nada, zip, nothing. OK, opened the door and placed the fob on the garage floor just underneath the door jam. Hit the start button, Now the display said place the fob against the start button and press the button.
So..... now, getting the RFID rolling code and figuring out what to do to actually drive away a much much harder job.
Conclusion. Likelyhood that anyone can actually do this kind of theft about 1,000x less likely than stealing a car WITHOUT a RFID chip.
Oh, and on my other two cars an even harder job. The thief would have to have an actual working Key with the RFID chip to drive the car away after using the fob to unlock and start the car.
I'd say rather than trying to trash the effectiveness of todays fobs and chip, we should be saying thank you thank you thank you to the mfg for doing something to make car thefts magnitudes harder than a few decades ago.
