Remote Lock Key Fob Function

Hi there, it's ME again lol.

Since I stripped the interior including the diversity attena on the roof and the infotainment harness I can't get my key fob to unlock either door or trunk. Car still turns on when I put the key into the slot and windows go down when I put the metal blade into the door handle.

I've tried researching and I can't get confirmation of what physical modules are actually needed.

Context:
1. Key fob turns car on when inserted into key slot
2. Central door lock button works fine
3. Metal Key fob when entered into door locks will unlock and roll windows down
4. Removed diversity attena and infotainment harness, tried plugging two of the three plugs on the diversity antenna and didn't help
5. Car now has no radio
6. Car has comfort access

Any help is greatly appreciated!

Also for further clarification

I was able to hook up the plugs for I and II but not III on the diagram below.

Not sure all three have to be plugged in or if there is a reset of the atenna that's needed?

Thanks!

This can all be answered by the proper wiring diagram. ISTA has these all available.

Something like this.
This makes it seem like the antenna is internal in the Aerial Diversity module.
