Keyless entry fobs result in rash of vehicle thefts

in security on (#8TR4)
story imageAs vehicles become more technologically advanced, thieves are becoming technologically savvy, too. Cars with a hands-free key fobs typically unlock a car within about 30 centimeters. But across the USA, thieves have begun using a device called a power amplifier to help unlock cars. The amplifier, which can cost less than $20 over the Internet - takes the signal from the car and projects it as far as 100 meters, so your car can find your key fob in your purse, pocket or the table where you dump your stuff when you come in the door.

In Toronto, Los Angeles, Long Beach, New York, Springfield, and more cities, police have reported a spike in thefts from Toyota and Lexus SUVs, Priuses, and more vehicles, all parked in owners' driveways with no signs of damage. As more people buy cars with these no-push key fobs, what's the solution to stopping this type of break-in? "Use a microwave" or wrap your keys in aluminum foil. The heavy metal cages block the signal. It's another case of convenience becoming a two-edged sword.

I don't assume. I ask. I would like to know more about the specifics... but not in the article. Yes, I can believe that the added functionality sends with the same power than all the other signals. In hindsight this is stupid, but as it is said: Hindsight is 20:20. At least it should be easy to fix... just limit the damn key to 30cm, too.

Btw... one of the reasons why I always refused security related projects. :-D
