Apply the serial number label to the anti-theft card, and give the card to the customer. Make sure the customer knows the importance of keeping the anti-theft code card in a safe place. Advise them to discard the original anti-theft code card. • To prevent unneeded troubleshooting, check the radio and HVAC functions, and verify that all functions are working before you begin.
