FACT CHECK: Code Grabbers and Remote Keyless Entry?

However, times change and technology advances. In response to the fixed code security weakness, automakers shifted from RKEs with fixed codes to systems employing rolling random codes. These codes change every time a given RKE system is used to lock or unlock car doors and thus rendered the earlier ‘code grabbers’ ineffective. That form of more robust code system became the industry standard for remote keyless entry systems in the mid-1990s, so automobiles newer than that are not vulnerable to being quickly and easily opened by criminals armed with the first generation of code grabbers.


Another thing not to worry about

1. I don't get "paranoid" about anything.

2. You may also want to reread your Snopes link again.

For the most part, any efforts by car thieves to steal vehicles by exploiting RKE systems have likely been supplanted by a much easier method, that of using boosting devices to relay the RKE signals from far enough away that the car’s owner is unaware of it:

Keeping Your Car Safe From Electronic Thieves - The New York Times

Let me explain: In recent months, there has been a slew of mysterious car break-ins in my Los Feliz neighborhood in Los Angeles. What’s odd is that there have been no signs of forced entry. There are no pools of broken glass on the pavement and no scratches on the doors from jimmied locks.

But these break-ins seem to happen only to cars that use remote keyless systems, which replace traditional keys with wireless fobs.

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.”

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.

...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.”

Which is why my car key is now sitting next to a tub of chocolate ice cream.
