I did some internet searching and came across a dealer pdf that say’s it is but just wanting to confirm. I’ll attach the PDF. For what it worth alarmgrid say’s it compatible for the GC3 on their site but I’m not sure if they are right either.
I kinda prefer in theory no keys, one less thing to defeat. In practice that may be something else entirely. I’m going to order it now so time will tell. Thanks for the input!
