<h1>2023 GMC Yukon – Smart Key Fob Programming Instructions</h1> <p><font size="3"><b>Important Note:</b> The 2023 GMC Yukon does not support onboard programming for smart key remote fobs. A new remote must be programmed using advanced diagnostic equipment by a trained automotive technician. </font></p> <p><font size="3"><b>Programming Procedure</b> </font></p> <ul> <li><font size="3">Step 1: Collect all remote fobs that you want to use with the vehicle. – In some cases, all remotes must be present during programming, as older keys may be erased from memory during the process. </font></li> <li><font size="3">Step 2: Contact a certified automotive technician or service provider who is experienced with keyless entry systems and equipped with the necessary programming tools. </font></li> <li><font size="3">Step 3: Schedule an appointment or, if the vehicle is operable, drive it to the technician’s location to minimize additional service charges. </font></li> <li><font size="3">Step 4: Be prepared to show proof of vehicle ownership (such as your registration and a photo ID). Most technicians will require this before programming for security reasons. </font></li> <li><font size="3">Step 5: The technician will connect a professional-grade diagnostic scanner to your vehicle’s OBD-II port to access the security and keyless entry system. </font></li> <li><font size="3">Step 6: The vehicle will be placed into key learning mode using the scan tool. At this point, previously stored keys may be cleared from memory, depending on the procedure. </font></li> <li><font size="3">Step 7: Each smart key fob will be programmed and verified by the technician. The vehicle may emit visual or audible cues (e.g., door lock cycling or chimes) to confirm that the new fob has been successfully recognized. </font></li> <li><font size="3">Step 8: Once all remote fobs are programmed, the technician will exit the programming mode and confirm that each remote performs the intended functions, including lock, unlock, remote start, and panic features. </font></li> <li><font size="3">Step 9: Before leaving, test each newly programmed remote to ensure full functionality with your vehicle. </font></li> <li><font size="3">Step 10: Store any spare fobs in a secure location, and consider noting how many total remotes are currently programmed to the vehicle for future reference.</font></li> </ul>
