Vehicle Burglaries with FOB Key Copies

By an edhat reader

There’s reportedly been a number of incidents of locked vehicles being opened and the contents stolen, where the perps remotely copy the driver’s FOB key, open the car without having to break in, and take anything of value, especially credit cards.  There’s no way for the driver to know his/her key has been remotely copied, and the vehicle is vulnerable to being opened.

I’ve seen NextDoor reports of it happening at the Elings Park parking areas, and was there today at the Hendry’s Beach parking lot when it happened there.  As I understand it, when the driver locks the car using the FOB key, a team of at least two people, with one close enough to remotely copy that FOB key, copies it and send the info to another perp, and immediately they’re able to access the vehicle.  In some cases it’s enough to start the vehicle, and it’s stolen.

Not sure what law enforcement can do, or if this is an issue they want to address.  I’ve looked around on the internet for how to protect a FOB key from being copied and still be able to use it.  Faraday bags can protect the key when it’s not in use.  But how can you protect the key and your vehicle when you need it to lock your car from the outside?

  1. Good explanation for those of us not technically inclined:

    I realize this doesn’t address your concerns, but it is from 2015…
    “I finally found what seems like the most plausible answer when I spoke to Boris Danev, a founder of 3db Technologies, a security company based in Switzerland. Mr. Danev specializes in wireless devices, including key fobs, and has written several research papers on the security flaws of keyless car systems.
    When I told him my story, he knew immediately what had happened. The teenagers, he said, likely got into the car using a relatively simple and inexpensive device called a “power amplifier.”
    He explained it like this: In a normal scenario, when you walk up to a car with a keyless entry and try the door handle, the car wirelessly calls out for your key so you don’t have to press any buttons to get inside. If the key calls back, the door unlocks. But the keyless system is capable of searching for a key only within a couple of feet.
    Mr. Danev said that when the teenage girl turned on her device, it amplified the distance that the car can search, which then allowed my car to talk to my key, which happened to be sitting about 50 feet away, on the kitchen counter. And just like that, open sesame.
    “It’s a bit like a loudspeaker, so when you say hello over it, people who are 100 meters away can hear the word, ‘hello,’ ” Mr. Danev said. “You can buy these devices anywhere for under $100.” He said some of the lower-range devices cost as little as $17 and can be bought online on sites like eBay, Amazon and Craigslist.
    Mr. Danev said his company was in talks with several car manufacturers to install a chip that can tell how far the key is from the car, thereby defeating the power-amplifier trick.
    While I can’t be 100 percent certain this is the device they used to get into my car, until car companies solve the problem, he said, the best way to protect my car is to “put your keys in the freezer, which acts as a Faraday Cage, and won’t allow a signal to get in or out.”

  2. I was suspicious of this exact key fob thing when I was at a hotel cuz I saw my lights blink when I was walking away and didn’t touch any buttons. Unsure if it was a pocket press or a booster attack, I went back real quick and I yanked my car battery (in the trunk for some reason) and then put my key in an aluminum foil taco. If it was a hacker thief, I’d like to have seen the look on their faces and the head scratching “oh man why isn’t it working anymore?” Was probably just a pocket press but I had the extra 20 seconds to not take that chance.
