Having issues with your Corvette C6 Key Fob? Whether you’ve added a new fob or need to reprogram your existing ones, understanding the correct procedure is crucial. This guide provides a comprehensive, step-by-step walkthrough for programming your Corvette C6 key fobs, ensuring you maintain seamless access to your vehicle.
This procedure is designed to program all your key fobs, effectively starting fresh. It’s important to follow these instructions carefully to avoid any issues and ensure successful programming. Let’s get started.
Step-by-Step Programming Instructions:
-
Prepare Your Vehicle: Begin by rolling down the driver’s side window and ensuring your Corvette C6 is completely turned off. Open both the trunk and the glove box.
-
Remove All Fobs: Crucially, make sure absolutely no key fobs are within range of your vehicle. This is a critical step to prevent interference during the programming process.
-
Initiate Programming Mode: Locate the key cylinder in the trunk. Insert your key into the trunk keyhole and rapidly turn the key five times within a 5-second timeframe. This action signals the system to enter programming mode.
-
Observe the DIC Message: After correctly performing step 3, the Driver Information Center (DIC) will beep and illuminate, displaying the message “Off/Acc to learn”. This confirms that your Corvette C6 is now in key fob learning mode and ready for programming. If you decide to cancel the programming at this stage, simply press the top portion of the Start button to return the car to its normal state. However, to proceed with programming and erase all previous fobs, continue to the next step.
-
Start the 30-Minute Programming Cycle: Press the bottom half of the Start button. The DIC will then display a message indicating a 10-minute wait period and begin counting down from 10 minutes. During this countdown, you are free to close the trunk and car door.
-
Repeat the 10-Minute Wait (Two More Times): After the first 10-minute countdown concludes, the DIC will again show “Off/Acc to learn”. Press the bottom half of the Start button once more. The DIC will initiate a second 10-minute countdown. Repeat this process a third time after the second countdown finishes; press the bottom half of the Start button to start the final 10-minute countdown. This extended 30-minute process is essential for clearing the system and preparing it for new fob programming.
-
Programming Fob #1: Once the third 10-minute period ends, the DIC will display “Ready for Fob #1”. At this point, the system is ready to learn the first key fob. Take your first key fob and insert it into the glove box slot. Ensure the fob is placed with the buttons facing towards the passenger side of the vehicle and the keyring end pointing outwards.
-
Program Subsequent Fobs: After approximately 3 to 4 seconds with the first fob in the slot, the DIC will beep and display “Ready for Fob #2”. If you have additional fobs to program, insert the next fob into the glove box slot in the same orientation as the first. The Corvette C6 system can accommodate up to four key fobs. Repeat this step for any remaining fobs you wish to program, up to the four-fob limit.
-
End Programming Session: When you have programmed all desired key fobs, or if you are only programming one, press the bottom half of the Start button to conclude the programming session.
-
Test Your Fobs: Thoroughly test all buttons on each programmed key fob to verify they are functioning correctly. After confirming button functionality, move all fobs away from the vehicle. Then, test each fob individually to start the car, ensuring each one is properly recognized and working.
Important Notes and Considerations:
-
Canadian and European Models: Be aware that Canadian specification Corvette C6 models may only support the shorter programming procedure for adding fobs, while the long procedure might require dealership programming. European specification models typically require all key fob programming to be performed exclusively by an authorized dealer.
-
Battery Maintenance: The 30-minute programming procedure can place a significant drain on your vehicle’s battery. To prevent potential issues or programming failures due to low battery voltage, it is highly recommended to connect a battery tender to your Corvette C6 throughout the programming process. This ensures a stable power supply.
-
Cell Phone Interference: Some reports suggest that having a cell phone on your person during the long programming method could potentially cause interference, particularly during step 9, and prevent the correct system response. It may be advisable to keep your cell phone away from you and the vehicle during the programming process to minimize any potential interference.
By following these detailed steps and considering the important notes, you should be able to successfully program your Corvette C6 key fobs. Always double-check each step and ensure you understand the warnings to avoid any complications. Enjoy the convenience of your newly programmed key fobs!
