The receiver is not your problem. Sounds like you have one bad fob and one bad tpms. You can try resoldering the connections in the fob. Search (using google) 'corvette forum legendary fix"

yeah
I resolered teh chips in both but was still losing sync every day
So i resoldered the antenna on the receiver which was Very loose.
It then held the code for a week then i had to disconnect teh receiver to put it back in place. Now i cant get tehe2nd fob to resync.
So i think u all may be right. I have a club member close by with a 97 coupe gonna try and get with him and try his fobs and see how that works

relation
From what i have been told both key fobs and TPMS units work thru the same receiver . In a convertable it is mounted behind the drivers side rear radio speaker. U might want to pull it out and open it and make sure the antenna part is well attached. Mine was so loose it almost just fell off. So start by looking there and also put new batteries in the key fobs

FOB Receiver
There is one receiver in the car and there are two types of transmitter devices , TPMS and key FOB's.
The transmitters encode a signal and data and transmit it. The Receiver decodes the signal (figures out which device sent the transmission) and passes the data to the BCM, PCM and IPC.
Other than both the TPMS and FOB's using the same receiver, there is no interaction between FOB's and TPMS.
You likely have two problems, bad batterys in the TPMS if they are original to the car and bad FOB's with broken solder joints on the circuit boards of the FOB's. The link that 65GGvert posted above addresses the solder joints in the FOB's. Here is a thread on replacing the batteries in the TPMS:

I'm having similar issues but also getting a code for "No Communication" with the receiver. How do I trouble shoot/test the receiver?I did check the wiring harness connection and it seems fine.
