C6 Corvette Key Fob Programming

C6 Corvette Key Fob Programming Banner

The Keyless Entry/Starting System on the C6 Corvette is a complex network consisting of radio transmitters, receivers and modules. The system uses multiple antennas to receive key fob signals. These antennas then direct the signals to the Remote Control Door Lock Receiver (RCDLR) and then to the appropriate modules. In this article we will introduce you to the system and help you better understand the key fob programming process. If at any time you get stuck or need help, visit the Request Support section and a Corvette Salvage representative will provide assistance.

Keyless Entry/Starting System: Parts Explained

  1. Remote Control Door Lock Receiver (RCDLR) – This receiver recognizes the key fob reception via the antennas and communicates the signals to the Body Control Module (BCM). Each C6 Corvette is equipped with 4 antennas; one in each door, one in the rear decklid, and one low frequency antenna located in the glove box compartment.
  2. Body Control Module (BCM) – This module sends starter and fuel enable signals to the Powertrain Control Module (PCM) when the correct key fob information is received from the RCDLR.
  3. Key Fob/Transmitter – Two transmitters are shipped with every Corvette purchased from the dealer. Each car can have up to four key fobs programmed to it. There are limitations. Only two key fobs will be programmed to the memory package of the vehicle, the other two will only control the door and engine start functions.
  4. Door Control Modules (DCM) – These modules are found in each door and communicate with the BCM to lock and unlock the doors.

Pre-Warnings & Considerations

AUTO LOCK DISCLAIMER: It is recommended to disable the auto lock feature before starting the programming procedure. If auto lock is enabled, the car may lock itself and activate the anti-theft deterrent system during the procedure.

BATTERY DISCLAIMER: It is recommended to attach a battery charger to the car before starting the programming procedure. A low battery can cause unexpected behavior from the car.

CANADIAN DISCLAIMER: Corvette models made for export to Canada can follow Procedure #1 (The SHORT Version). Procedure #2 (The LONG Version) can only be performed by a dealer.

CELL PHONE DISCLAIMER: It is recommended to remove cell phones from the car while performing the programming procedure. Cell phone signals could interfere with the ‘programming antenna’, disrupting the process.

DEFECTIVE SLOT DISCLAIMER: If the glove box slot is not working properly and Procedure #2 (The LONG Version) is started, all current key fobs programmed to the Corvette will be deleted. This will prevent the car from starting and the car will not be able to accept a new key fob until the slot is fixed.

EUROPEAN DISCLAIMER: Corvette models made for export to Europe cannot follow either procedure. Key fobs for European Corvette models must be programmed by a dealer.

KEY FOB NUMBER DISCLAIMER: Numbers printed on the key fobs (Ex. 1, 2, 3, 4) only indicate the sequence in which it was first programmed at the factory. All key fobs are identical. If you want the key fobs to be programmed according to number, the order in which the fobs are placed in the glove box slot determines which number is on the fob. Otherwise, the number is irrelevant.

Key Fob Programming Prep: Glove Box Slot Setup & Testing

Glove Box Slot Setup

Before programming can begin, the key fob must be properly placed inside the designated glove box slot. It can be found on the left hand side of the glove box once the lid is opened. The slot has no electrical hookups and therefore will not require a direct, wired connection to the key fob. It simply serves as a resting place for the key fob and perfectly positions the fob next to the ‘programming antenna’.

When inserting the key fob into the slot, the end of the fob with the key ring MUST face outwards AND the key fob buttons MUST face towards the passenger side of the vehicle.

Glove Box Slot Testing

Before starting the programming procedure, it is important to test the glove box slot to make sure it is working properly. Follow the steps below to test it:

  1. Start by placing the Corvette in accessory mode and roll the DRIVER SIDE window all the way DOWN.
  2. Next, turn the car OFF.
  3. UNLOCK the car and OPEN the trunk.
  4. OPEN the glove box.
  5. REMOVE the physical metal key from the currently programmed key fob and INSERT it in the trunk key hole. TURN the key five times in less than 5 seconds. The Driver Information Center (DIC) will beep and read “Ready for fob 3”.
  6. PLACE the metal key back into the key fob and INSERT the currently programmed key fob into the glove box slot. (Must be positioned properly, read red text above for proper positioning instructions.) If the key fob slot is working and is presented with a ‘known’ fob which is ALREADY programmed to the car, the DIC will read “Known Fob”. If this message does not show up, the slot is not working properly and it is strongly advised not to continue with the programming until the slot is fixed.
  7. PRESS the bottom half of the start button to end the testing session.

NOTE: If the testing failed, it is likely that the ‘programming antenna’ in the glove box is defective, unplugged or not properly positioned. Removing the glove box can help diagnose the problem. If the antenna is defective, a new one can be purchased below.

PROCEDURE #1: The SHORT Version

Procedure #1 can be used when you have a working key fob CURRENTLY programmed to the car and you want to add another.

  1. Start by placing the Corvette in accessory mode and roll the DRIVER SIDE window all the way DOWN.
  2. Next, turn the car OFF.
  3. UNLOCK the car and OPEN the trunk.
  4. OPEN the glove box.
  5. REMOVE the physical metal key from the currently programmed key fob.
  6. PLACE the currently programmed fob on console next to shifter and INSERT the metal key into the trunk key hole.
  7. TURN the key five times in less than 5 seconds. If it is done correctly, the Driver Information Center (DIC) will beep and read “Ready for fob 3”.
  8. PLACE the new un-programmed key fob into the glove box slot with the key ring facing outwards and the buttons facing the passenger side of the vehicle.
  9. WATCH the DIC. When it reads “Ready for fob 4” the programming is complete. The maximum amount of key fobs which can be registered to each car is four.
  10. Once all key fobs are programmed, PRESS the OFF/ACC (bottom half of the start button) to turn the DIC off.
  11. REMOVE the newly programmed key fob from the slot and TEST all four buttons to make sure it works. REMOVE all key fobs from within the car and, one by one, try using each to start the car.

Procedure #2: The LONG Version

NOTE: This procedure requires three consecutive ten minute waiting periods and will take about half an hour to perform. The car cannot be moved during this programming period.

  1. Start by placing the Corvette in accessory mode and roll the DRIVER SIDE window all the way DOWN.
  2. Next, turn the car OFF.
  3. UNLOCK the car and OPEN the trunk.
  4. OPEN the glove box.
  5. REMOVE the physical metal key from one of the key fobs AND make sure NO key fobs are located anywhere near the car.
  6. INSERT the metal key into the trunk key hole.
  7. TURN the key five times in less than 5 seconds. If it is done correctly, the Driver Information Center (DIC) will beep and read “Off/Acc to learn” If you decide at this point NOT to do the programming, press the TOP half of the Start button and the car will return to normal. When performing the next step, all previous key fobs will be erased.
  8. To continue with the programming, PRESS the BOTTOM half of the Start button. The DIC will enter into a 10 minute waiting period and will start counting down. The trunk and car door can be closed while waiting for the ten minute countdown to complete.
  9. After the first 10 minute countdown is complete, the DIC will again say “Off/Acc to learn”. PRESS the BOTTOM half of Start button again. The DIC will again enter into a 10 minute waiting period and will start counting down.
  10. After the second 10 minute countdown, the DIC will again say “Off/Acc to learn”. You guessed it, PRESS the BOTTOM half of Start button again. The DIC will enter into a third 10 minute waiting period and will start counting down.
  11. After the third ten minute waiting period is over, the DIC will read “Ready for Fob #1”. Regardless of the number on the key fob, the FIRST fob that is put in the glove box slot will be recognized as Fob #1. PLACE the first key fob into the glove box slot with the key ring facing outwards and the buttons facing the passenger side of the vehicle.
  12. After 3 to 4 seconds, the DIC will beep and read “Ready for Fob #2”. REMOVE the first key fob from the slot and PLACE the second key fob into the slot. The car can program a maximum of four key fobs.
  13. When all key fobs have been programmed, PRESS the BOTTOM half of the Start button to end the programming session.
  14. TEST all four buttons on each key fob to make sure they work. Then, REMOVE all key fobs from within the car and, one by one, try using each to start the car.
