reprograming 98 vette remote entry
You must own this vehicle and have the keys to it.
Only because I know this information is available and on the internet, do I post it.
The transmitter may not communicate or become out of synchronization with the receiver if any of the following situations occurs:
*The transmitter battery is disconnected.
*The vehicle battery is disconnected.
*The transmitter and the vehicle are separated for 2 weeks or more.
*The receiver is disconnected.
Perform the synchronizing procedure if the transmitter does not communicate or becomes out of synchronization with the receiver. If the transmitter and/or receiver are replaced, preform the following programming procedure:
Programming Transmitters
1 - Turn the ignition to ON.
2 - Turn the radio to OFF.
3 - Press the RESET button in order to clear any IPC warning messages.
4 - Press and release the OPTIONS button on the DIC (Driver Information Center) to scroll through the display options until the IPC (Instrument Panel Cluster) display is blank.
5 - Press and hold the RESET button for 3 seconds.
6 - Press the OPTIONS button until FOB TRAINING message is displayed.
7 - Press the RESET button in order to begin the programming sequence. The message HOLD LK + UNLK 1ST FOB will be displayed.
8 - Simultaneously press and hold the LOCK and UNLOCK buttons on the first transmitter for 15 seconds. The IPC will indicate when that transmitter is programmed and when to proceed to the next. Repeat this procedure for each additional transmitter or press the OPTIONS button to exit.
Programming Cancellation

*The program mode is exited through the DIC.
*The ignition is turned to OFF.
*The three transmitters have been programmed.
*The RFA system has been in the program mode for longer than 2 minutes and no transmitters have been learned.
If the program mode is cancelled with less than three codes stored, the receiver will only accept the codes just stored. If the program mode is cancelled before any code is stored, the codes still remain valid.
The receiver retains all current access codes in memory if either of the following conditions occur:
*A programming sequence is interrupted.
*The battery is disconnected.
Synchronizing Transmitters
Perform the following procedure if a transmitter cannot communicate or becomes out of synchronization with the receiver:
1 - Move a programmed transmitter within range.
2 - Press the LOCK and UNLOCK buttons on the transmitter simultaneously for 7 seconds.
3 - The horn will chirp once when the transmitter is synchronized. Repeat this procedure for each additional transmitter if needed.

Comments
Any electrical geniuses out there that can explain to me and the Chevrolet technicians what is wrong and how it can be fixed...
Is the remote getting near something with high electrical output or something big magnetically?
Ok, one remote works fine all the time?
The other, doesn't?
Or is it only one that you have and it isn't retaining the memory?
If so, then I seriously doubt it is a remote problem, more so as a problem with the controller on the vehicle.
Remote Keyless Entry Operational Characteristics
1997-2000 All Passenger Cars and Trucks
with Remote Keyless Entry
The following information regarding Remote Keyless Entry (RKE) operation may be given to customers as needed.
The General Motors RKE systems operate on high frequency radio signals. Therefore, they may be subject to radio signal interference which will affect RKE operation. Some of the typical conditions which
result in reduced RKE transmitter operation are listed below.
If on the second press of the unlock button, all doors are not unlocked, it may be due to the time delay needed by the system to recognize the second press of the unlock button. In order to unlock all
doors, press the unlock button once, pause 1-2 seconds and press the unlock button the second time.
Important
There needs to be a pause between button presses so that the receiver can properly process the signal from the transmitter.
Line of sight. The transmitter signal may be obstructed by obstacles; another vehicle, building or other obstructions in the line of sight.
Proximity to radio towers, airports, police and fire towers.
The presence of fluorescent lighting.
Installation of some aftermarket accessories have been known to affect the RKE performance as well.
Some brands of radar detectors, CB radios, walkie talkies, mobile radios and cell phones (especially 3-watt bag phones which are placed on the floor of the vehicle) have jammed the radio
frequencies of the RKE system.
Remember, these devices do not have to be in the customer's vehicle. They may be in another vehicle which is in close proximity. However, if the customer has one of these devices in their
vehicle and if the RKE system works with these aftermarket devices unplugged, refer the customer to the aftermarket supplier. The aftermarket device may not meet the requirements of the
FCC Code.
If the customer comments that the remote transmitter fails to operate, press each button on the transmitter one at a time while observing the vehicle systems.
If only the fuel door (Cadillac), or panic button (all other vehicles) works, re-synchronize the system, following the transmitter synchronization procedure found in the Keyless Entry sub-section of
Body & Accessories in the Service Manual.
DO NOT REPLACE ANY COMPONENTS.
Important
Re-synchronization must be performed if the following conditions exist:
The batteries of the keyless entry transmitter have been replaced.
A keyless entry transmitter is malfunctioning.
If all of the transmitter buttons fail to function, check the battery and transmitter using tester J 43241. Refer to Corporate Bulletin Number 83-90-12.
If the transmitter passes the test, program the RKE system following the procedures in the Keyless Entry sub-section of Body & Accessories in the Service Manual.
Important
Remember when programing the system, all transmitters for the vehicle must be present for the programming to be successful.
If the transmitter fails the test with the tester J 43241, replace the batteries and retest the transmitter using the tester J 43241. If the transmitter still fails the test, replace the transmitter.
THE FOLLOWING CLAIM TYPES ARE NOT COVERED UNDER THE VEHICLE WARRANTY:
The battery is considered a consumable battery and is covered for the first 12 months only. Refer to "Maintenance" in the In-Vehicle Warranty Booklet. Battery life is determined by the number of
times a pad on the transmitter has been used, not by time or mileage and as such, battery replacement would be considered owner maintenance (i.e. batteries in a flash light, engine oil changes).
Transmitter replacement when all buttons work, using the tester J 43241, as outlined in Corporate Bulletin Number 83-90-12.
Personalization programming through the DIC or Tech 2.
Lost/replacement transmitter reprogramming.
Used car transmitter replacement programing.
Transmitter damage due to misuse, such as any liquid spilled on/in the transmitter or damage from animals chewing on the transmitter, etc.
Broken transmitter cases where the key ring attaches to the case. If the case is broken in this area, it is due to mounting the transmitter direct to the key ring without the protection of the small ring.
The small ring acts like a universal and helps protect the transmitter from this type of damage.
Garage door opener programing.

Each transmitter has a unique Vehicle Access Code (VAC) that changes every 5 seconds. If a transmitter or receiver is replace, each transmitter must be programmed to the vehicle's receiver. Entering a
specific button sequence on the DIC, up to three transmitters can be programmed into the receiver. After programming the transmitters to the vehicle, the receiver will update this code every 5 seconds in
order to match the code programmed in the transmitter.
The transmitter may not communicate or become out of synchronization with the receiver if any of the following situations occurs:
The transmitter battery is disconnected.
The vehicle battery is disconnected.
The transmitter and the vehicle are separated for 2 weeks or more.
