Unfortunately you may be looking at a trip to the dealer for this. If the RCDLR is defective it will need to be replaced and a Tech 2 is required to set-up the fobs again. If the module has "forgotten" the fobs for some reason, you still need a Tech 2 to reprogram them but I don't believe this isn't a common situation. I haven't heard of many cases of this occurring.
It'* not surprising that you didn't find a bad fuse, unless you have other problems with your vehicle. The RCDLR doesn't have a fuse of its own and therefore if it were bad, you'd also have other things not working in your car.
The RCDLR is a Class 2 serial device. There are two serial lines running to this device so it'* unlikely a data bus wiring issue (due to the redundancy). By pulling the RCDLR out of your vehicle, you will have set a DTC. Under normal circumstances, this will clear on its own after 50 ignition cycles with no problem (IIRC).
