Key fob resynchronize
i own a 1999 stock corvette.
the car battery is new and so are the batteries in the keys fobs.
after the car sits overnight i have to resynchronize the key fobs like when you disconnect the battery, by holding down the lock and unlock buttons at the same time.
everything works fine then.
next day i will have to resynchronize again.
i have owned the car 20 years, never did this before.
any ideas.?
thanks guys.





If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of three
transmitters matched to it.
To match transmitters to your vehicle:
1. Turn the ignition key to ON.
2. Clear any warning messages on the Driver Information Center (DIC) by pressing the RESET button.
3. Press the Options hlltton on the DIC several times until the blank page is displayed, then press and hold the RESET button for two seconds.
4. When the message FOB TRAINING is displayed, press the RESET button once. The message HOLD LK + UNLK 1ST FOB will be displayed in
the DIC.
5. Press and hold the lock and unlock buttons on the first transmitter simultaneously for five seconds.
6. When a transmitter is learned (matched), the DIC will display FOB LEARNED and then prompt you to learn the second transmitter.
7. Repeat Steps 5 and 6 for the third transmitter.
8. Remove the key from the ignition.
.
The Programming mode will shut off if any of following has occurred:
You don’t program any transmitters for two minutes.
You take the key out of the ignition
You have programmed three transmitters.
