I was robbed

Recommended Posts

The mere possibility that I don't always do that is getting me more than a little paranoid and I've taken my fob to the window and 'locked' the car several times since this has happened just for peace of mind.

Same here. On multiple occasions I have done this from my hotel room window (even from the fourth floor) where I can see my FFH. It is reassuring to push the lock button on the fob and see him flash his lights.

 

There is a relatively inexpensive piece of hardware that can be used to unlock your car. The crook walks up to the car and touches the door handle. The car transmits a who is there question. Normally your fob is too far away (more than about 3 feet) to hear it and nothing happens. The hardware receives the signal and re-transmits it at a much higher power than the car uses. Your fob hears the signal and transmits the I am here response. The key transmits at a high power (so you can lock and unlock from a distance) and the car hears it and validates the response and unlocks the car. Wrap all of your fobs in two layers of aluminum foil or secure them in a metal box when at home or anywhere where you are within fob transmit range of the car. They can't steal the car this way but can easily get in. Also the button to the left of the steering column makes it trivial to open the trunk once inside. The alarm is off when the car is unlocked.

I have the simple basic fob for my FFH S (no door keypad). Is my FFH also vulnerable to the technique you are describing here?
