2. Step-by-Step Programming Guide for 2008 Chevy Silverado Key Fob

Follow these detailed instructions to program your 2008 Chevy Silverado key fob, whether your vehicle has Driver Information Center (DIC) buttons or not.

2.1 Programming with Driver Information Center (DIC) Buttons

For vehicles equipped with DIC buttons, follow these steps:

Insert and Turn the Key: Insert your key into the ignition and turn it to the “ON” position. Ensure you do not start the engine. This activates the Driver Information Center.
Navigate to Relearn Remote Key: Press the vehicle information button until you see “PRESS TO RELEARN REMOTE KEY” displayed on the DIC screen.

Program the Key Fob: Simultaneously press and hold the lock and unlock buttons on the keyless remote for about 15 seconds. You will hear a chime indicating that the remote is programmed.
Program Additional Remotes: If you have additional remotes to program, repeat step 4 immediately. Your vehicle can store up to eight remotes.
Exit Programming Mode: Turn the key off and remove it from the ignition. Test all programmed remotes to ensure they function correctly.

2.2 Programming without Driver Information Center (DIC) Buttons

For vehicles without DIC buttons, use this procedure:

Prepare the Vehicle: Ensure your vehicle is in Park (P) and the key is in the “ON” position (as far as you can turn it without starting the engine).
Enter Relearn Mode: Press the trip odometer reset stem until “RELEARN REMOTE KEY” is displayed on the instrument panel.
Activate Learning Mode: Press and hold the trip odometer reset stem for three seconds. The message “REMOTE KEY LEARNING ACTIVE” will appear, indicating the vehicle is ready to program a key fob.
Program the Key Fob: Press and hold the lock and unlock buttons on the first keyless remote simultaneously for approximately 15 seconds. A chime will sound, confirming that the remote is programmed.
Program Additional Remotes: To program additional remotes, repeat step 4 immediately. The system allows programming up to eight remotes.
Exit Programming Mode: Turn the key off and remove it from the ignition. Test each remote to verify successful programming.

2.3 Key Programming Tips and Tricks

Battery Check: Ensure the key fob battery is fresh. According to a study by AAA, a weak battery is a common cause of programming failure.

Install a Vehicle Security System: Consider installing an aftermarket vehicle security system with advanced features like GPS tracking and remote monitoring.

If your key fob is lost or stolen:

Report to Police: File a police report to document the incident.
