Default BO-RFA - No Comm message code

After having the battery disconnected for a couple weeks on my '03 Z06, my key fobs don't work any longer, even with fresh batteries.

I've tried a few times to reprogram through the DIC, as well as trying to resync by holding the buttons down for 15 seconds, with no luck.

It seems there is no communication between the computer and the RFA box - the little black box behind the left rear fender that controls the key fobs. I've verified that it is properly plugged in, still nothing.

The computer has the code: BO-RFA - No Comm

Has anyone run into this issue?

Happened to me when the body shop forgot to plug in my module after getting the car fixed.

That's what I thought as well (as my car too was in the body shop) but I've checked it and it seems fine.

It's the little 2x2" black box in the fender correct? There's a small clip-on fitting with 3 small wires going into it.

Could it be that the box went bad?

I didn't see the box myself. But I was told it is in the driver's side rear of the car. Possibly accessable via a cover in the rear hatch? I think there's also a fuse for it somewhere....
