Do you know about the little ‘hidden’ feature on your key fob? Using this disables the ability for anyone to use a remote scanner for the wireless code your fob always transmits. I also use a Faraday pouch when I’m in the house.
Just hold down the lock button while double tapping the unlock button. You’ll see a red light in the key fob blinking to show that the transmitter has been disabled. You can confirm this by attempting to open your car by pulling on the door handle. The puddle lights are also disabled.
Press any key on your fob to return everything back to normal.
