Hi, I would like to share how I handle with this issue. You can just switch off your key fob. If you press and hold the lock button and in the same time press quickly twice the unlock button the key fob stops the transmitting. So no one is able to catch the signal. Of course, it is not very convenient to do it every time but you can decide whether to do it or not. There is one more benefit - in this way you will safe your battery life for long time.
