• Vehicle System Issues: There may be an underlying issue with the vehicle’s security system.

Troubleshooting Steps:

1. Replace the Battery: Replace the battery in the key fob with a new one. Ensure the battery is correctly installed.
2. Re-try Programming: Carefully repeat the programming procedure, making sure to follow each step precisely.
3. Test the Key Fob: Use a key fob tester to check if the key fob is transmitting a signal.
4. Check Vehicle’s Battery: Ensure the vehicle’s battery is fully charged, as a low battery can sometimes interfere with the programming process.

3.2. “Remote Key Learning Active” Not Displayed

Possible Causes:

• Incorrect Procedure: The wrong procedure may have been used for your vehicle type (with or without DIC).
• Timing Issues: The timing of button presses may be off.
• System Error: There may be a temporary glitch in the vehicle’s system.

Troubleshooting Steps:

1. Verify Procedure: Double-check whether your vehicle has a Driver Information Center (DIC) and use the corresponding procedure.
2. Adjust Timing: Try adjusting the timing of your button presses. Some vehicles require precise timing for the programming to work.
3. Restart the Process: Turn the ignition off, wait a few seconds, and then restart the programming process from the beginning.
4. Check Fuses: Inspect the vehicle’s fuses related to the remote keyless entry system. A blown fuse can prevent the system from entering programming mode.

3.3. Vehicle Not Chimes

Possible Causes:

• Key Fob Issue: The key fob may not be transmitting the correct signal.
