After service, reconnect power to the audio-navigation unit or the audio unit, and turn the vehicle to the ON mode. There are two ways to exit the anti-theft mode:

Press and hold the POWER button for at least 2 seconds. The audio-navigation unit or the audio unit automatically exits the anti-theft mode. If the audio-navigation unit or the audio unit does not exit anti-theft mode, like in cases where a known-good unit was substituted for testing, enter the anti-theft code.
Enter the 5-digit anti-theft code.

There are no anti-theft cards included with the vehicle. If you need the code, you can get the code from the Interactive Network (iN) using the audio-navigation unit or the audio unit serial number. The unit serial number can easily be obtained without removing the audio-navigation unit or the audio unit, do the following:

With navigation: Go to Anti-Theft Future in How to Troubleshoot the Navigation System .
Without navigation: Go to How to Obtain the Audio Unit Serial Number in Self-Diagnostic Function - Refer to: How to Troubleshoot the Audio System Audio System Self-Diagnostic Function .

After you retrieve the serial number, go to the iN, select Service, Vehicle Information, Anti-Theft Code Inquiry, and fill out the form.

When the audio-navigation unit or the audio unit is installed in another vehicle (same Year/Model/Trim), you have to enter the 5-digit anti-theft security code. After that, you can release the anti-theft mode by pressing and holding the VOLUME/POWER knob or the POWER button.
