Perhaps you’ve seen the words “code grabber” and “signal repeater” in the news and wondered what they mean jamming auto.

Defining a Signal Grabber?

At a basic level, a code grabber is a tool built to capture the radio signal emitted by a electronic key to a vehicle. The idea is to capture that command and exploit it illegally. In the real world, these gadgets exist overwhelmingly to commit crimes.

What Is a Relay Repeater?

This second type of device works differently. Rather than storing a code, it extends the range of a key fob that is resting inside a home. The consequence is that a vehicle can be fooled into thinking the legitimate fob is present. Just like grabbers or keyless repeater, these gadgets are exploited overwhelmingly for crime.

Defending Your Vehicle

Encouragingly is that there are ways to lower your exposure. Keeping your remote key in a protective sleeve helps stop illegitimate attempts. A physical lock and good habits also make a difference.

Final Thoughts

Code grabbers and signal repeaters are not tools for the curious — they are tools built for theft keyless repeater. Understanding them is valuable only so you can defend yourself. Owning them, however, is simply wrong.
