key fob security is both good and bad
A lot of people use keyless entry for their cars. And it's known to many that anything transmitted can be intercepted. So I wasn't surprised at all that if one is patient enough they can crack the frequency for keyless entry for your car.
Do you need to worry about having your car broken into since it's possible to do this?
You're only susceptible to this if:
- Your car is worth stealing.
- Something in your car is worth stealing.
- You use your fob in a dense area.
"3" is the one to pay attention to. In order to crack a keyfob's frequency, equipment has to be in place to "listen" for it when you trigger the door unlock. If you don't use the fob, it never transmits and the would-be thieves' equipment has nothing to receive.
