Alarm / door lock Key fob receiver

i had the dealer shut off the receiver (for the key fobs) for the car alarm and door locks a few years ago. I was getting some sort of radio interference that was constantly activating the alarm late at night.

Now i would like turn on the receiver, since the vehicle is now at a different location. anyone know where to look? I can manually activate the alarm with the driver side door lock, but would like to have the key fobs working again.

Thanks

stopped by the dealer this pm, they reactivated it free of charge. Originally they had disconnected a relay that is located behind the panel on the right side in the rear cargo area. This disabled the receiver for the key fobs.
