Just for the heck of it I entered the FCC from the remote control for a '96 G20 factory alarm and this is what I found out:

FCC request came from Alpine Electronics Inc. Iwaki-Shi Fukushima-Ken, Japan.

By the way, does anyone have the actual Nissan/Infiniti Part # for a replacement remote for the '96 G20?

Thanks

The remote info is on this page:
