Defining a Signal Grabber?

What Is a Relay Repeater?

The consequence is that a locked door can be deceived into believing the legitimate fob is present. As before or car code grabber, such tools are used for the most part for illegal access.

Why You Should Never Use Them

On top of the criminal exposure, you also face the simple fact that they hurt real people. Property crime affects everyday families who suffer the loss of something they worked for.

How to Protect Yourself

Encouragingly is that there are ways to minimize your vulnerability. Storing your key fob in a shielded case can help prevent illegitimate access. An old-fashioned deterrent and awareness also help a lot.

The Takeaway
