Is the DGD-KIM protected against “Code grabbers”?

Yes, each Dawg Tag uses what’s called “rolling code” meaning that when it sends a code to the module, the next time they communicate they will use a different a code. This code uses a complex algorithm; so that even if someone stole your code, the next time your system and Dawg Tag communicate the old code that was “grabbed” is no longer valid and will no longer authorize the module.
