Wirelessly unlocking your car is convenient, but it comes at a price. The increasing number of keyless cars on the road has led to a new kind of crime — key fob hacks! With the aid of new cheap electronic accessories and techniques, a key fob’s signal is now relatively easy for criminals to intercept or block. Imagine a thief opening your car and driving away with it without setting off any alarms!
According to the FBI, car theft numbers have been on a downward spiral since their peak in 1991. However, numbers have been steadily inching their way up again since 2015. In fact, there was a 3.8 percent increase in car theft cases in 2015, a 7.4 increase in 2016 and another 4.1 increase in the first half of 2017.
In order to fight this upward trend and prevent your car from becoming a car theft statistic itself, awareness is definitely the key.
So arm yourself against this new wave of car crimes. Here are the top keyless car hacks everyone needs to know about.

Always-on key fobs present a serious weakness in your car’s security. As long as your keys are in range, anyone can open the car and the system will think it’s you. That’s why newer car models won’t unlock until the key fob is within a foot.
However, criminals can get relatively cheap relay boxes that capture key fob signals up to 300 feet away, and then transmit them to your car.
Here’s how this works. One thief stands near your car with a relay box while an accomplice scans your house with another one. When your key fob signal is picked up, it is transmitted to the box that’s closer to your car, prompting it to open.
In other words, your keys could be in your house, and criminals could walk up to your car and open it. This isn’t just a theory either; it’s actually happening.
According to the German Automotive Club, here are the top cars that are vulnerable to key fob relay attacks:
Audi: A3, A4, A6
