Does anyone know how to reset the keyless remotes? I have two spares that won't work.

Does the owners manual say anything about it?
Try this.
All transmitters which are to be recognized by the PDM must be programmed in a single programming sequence. When using this program method, all previously programmed transmitters will be erased upon the receipt of the programming signal from the first transmitter.
The order in which the transmitters are programmed will determine its numbering position within the PDM memory. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. The number stamped on the transmitter case is for reference only; #2 can be programmed as #1, or vice versa. Additional unnumbered transmitters are also available.
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to 4 transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter programming mode.
Operate the transmitter functions in order to verify correct system operation.

If they were programmed at one time, and you changed the batteries, all you need to do is press LOCK and UNLOCK and hold them down together for 7 seconds to re-synchronize the remotes with the truck.
It wouldn't hurt to program them all together though, but if you have more than those 2, they ALL need to be programmed at the same time.
You want to make sure you have the correct remotes as well.
The basic system uses FCC: KOBUT1BT / GM: 15732803 and has LOCK, UNLOCK, and PANIC buttons.
The "deluxe" system has FCC: ABO1502T / GM: 16245100-29 and has LOCK, UNLOCK, and REAR 2X buttons.
