I was lucky enough to find one at a dealer in NY but cant seem to get it to program, Have gone through the steps and the PKE blinks but when I bring the Key Fob in range,it doesn't go solid..
Any ideas?

 

If the light blinks the PKE module is probably OK, it's safe (IMO) to concentrate on the fob as the problem. . Make sure you are shaking the fob a little (it transmits when it detects itself moving). Make sure the fob battery is good, if I remember right it needs to be at least 3.1v to work right. Make sure the battery is seated firmly and properly. You say you got it at a dealer, if new the battery will be "brand new" but many years old.

 

I'll try shaking the fob. I changed the battery with the same type to be sure but will check the seating.

 

Shaking the key fob worked.
I have an old Fob that came with the car which doesn't work. I naturally changed the battery. Are there any procedures which have been done to determine why it doesn't work...besides being really old?

 

I just reprogrammed my Fob. The procedures are the same to program a second and up to a third. Lucky you have two, most have none and some have one! When you are programming the first, it blinks once every second or two signaling that it took Key Fob one, then you can completely remove it from proximity of the car and while the PKE Light in the dash starts blinking ready again. Bring the second Key Fob into proximity of the car like the first Key Fob, the second Key Fob should registered by showing the PKE light flashing twice per second in the dash. Once it takes the second Key Fob, remove the second Key Fob and repeat for the third. You can program unto three Key Fobs.

Here is programming procedure a dealership sent me...

How to program PKE Key Fob

Replacing the battery in your transmitter will not require the transmitter to be reprogrammed to the PKE receiver. However, incorporating a new or additional transmitter
will need to be programmed into the PKE receiver.

The PKE system is capable of using three different transmitters, with each transmitter having its own distinctive VAC (Vehicle Access Code).
The transmitter programming mode is initiated by entering a specific button sequence on the DIC (Drivers Information Center) on your dash. To enter the transmitter programming mode use the following steps:

Move the transmitters to be programmed approximately 12-15 feet away from the car. Turn the ignition to the Run position, engine off.
Push the Trip ODO button once and release. Push the Trip ODO button again and hold for 5 seconds.
Within five seconds, push and hold the Fuel Info button for 10 seconds until the passive keyless lamp illuminates constantly.
Turn the ignition key to the Lock position with the key remaining in the ignition. The passive keyless system lamp should flash once per second, signaling that the system is ready to program the first transmitter. The number of times the light flashes corresponds to the number of the transmitter you’re programming. One flash per second is for the first transmitter, two per second for the second and three per second for the third. Bring only the transmitter to be programmed into range at this time.The Passive Keyless Entry light will come on and stay on, signaling that the code has been stored.
Move the transmitter out of range. The system light will flash again and the system is ready for the next transmitter. You can exit the programming mode by removing the key from the ignition or by turning the ignition on. Turning off the programming mode will not cancel the programming of any transmitters that have been previously programmed into the system. Bringing more than one transmitter into range at a time will make it difficult for the system to search for individual codes. The programming mode will automatically shut off after two minutes if no transmitters have been programmed or the key is removed.

Passive Unlock/Lock Enable/Disable Procedure

The passive unlock/lock disable procedure allows you the ability to turn off the passive function of the PKE system. The passive unlock/lock feature can be enabled or disabled with the following procedure:

First, a transmitter must be in range of the PKE receiver. The key must not be in the ignition. Push the door lock switch for approximately 5 seconds. The PKE module will then lock the doors and then will unlock the doors to verify the command has been sent. When the passive feature has been disabled, the “passive keyless entry” lamp will not illuminate when the key is first turned on before the vehicle is started. If the passive feature has been disabled, simply repeating the procedure above will enable the passive unlock/lock function. To verify the system has been enabled, the “passive keyless entry” lamp will illuminate when the key is first turned on before the vehicle is started.

Program One or Both Doors to Unlock When In the Passive Mode

On your C4 Corvette you can choose if you want the passenger door to unlock passively. The PKE will always unlock the driver’s door when the system is in the passive mode. To enable or disable the passenger door you can perform the following procedure:

First, a transmitter must be in range of the PKE receiver. The key must be in the ignition. With the ignition in the Off position. Push the door lock switch for approximately 5 seconds. The PKE module will then lock the doors and then will unlock the doors to verify the command has been sent. If the driver’s door only unlock option has been chosen you can always unlock the passenger door using the transmitter.

 

Thank you for the information.I have one programmed but he fob that came with car will not program .I changed the battery but think there might be another issue.Looking for ideas about what it might be.
Thank you

 

Look for broken connections and solder any problem areas. Does it have a little bearing that moves back and forth? It might be stuck in place or something. Here is the address of one of the engineers who designed the system. She sometimes will rebuild fobs for a fair price.
