<h1>Smart Key Remote Programming Instructions – 2004 Saturn Ion</h1> <p><font size="3"><b> Important Notice:</b> The 2004 Saturn Ion does not support onboard programming for smart key remote fobs. Programming must be completed by a qualified technician using specialized diagnostic tools that interface directly with the vehicle’s control modules.</font></p> <p><font size="3"><b> Step-by-Step Programming Instructions</b> </font></p> <ul> <li><font size="3">Step 1: Contact a Certified Automotive Technician Locate a professional technician with experience in electronic key systems and access to dealer-level diagnostic tools compatible with General Motors vehicles. </font></li> <li><font size="3">Step 2: Bring All Smart Key Remotes for Programming Take all key fobs you want to use. During programming, previously paired remotes may be erased, so each remote must be reprogrammed at the same time to remain active. </font></li> <li><font size="3">Step 3: Confirm the Vehicle Is Drivable If your vehicle is operational, it may be more cost-effective to bring it to the technician’s shop rather than requesting mobile service. </font></li> <li><font size="3">Step 4: Prepare Vehicle Ownership Documentation Be ready to provide proof of ownership, such as the vehicle’s registration or title, along with a valid government-issued photo ID. These documents are typically required to authorize the programming process—especially if all keys are lost. </font></li> <li><font size="3">Step 5: Technician Connects Diagnostic Equipment The technician will plug a scan tool into the OBD-II port under the dashboard. This equipment communicates with the vehicle’s body control module and immobilizer system to initiate key programming. </font></li> <li><font size="3">Step 6: Activate Programming Mode Using the diagnostic interface, the technician will enable the key programming mode. This allows the vehicle to recognize and store new remote fobs while removing any unrecognized or outdated entries. </font></li> <li><font size="3">Step 7: Program Each Remote Fob One at a Time Each smart key is programmed individually. The technician will test each one to confirm that it performs all required functions, such as locking and unlocking doors, trunk release, and panic functions (if equipped). </font></li> <li><font size="3">Step 8: Finalize the Process and Exit Programming Mode Once all remotes are programmed, the technician will save the new data and exit the diagnostic system. </font></li> <li><font size="3">Step 9: Test All Programmed Remotes Ensure that each programmed remote is fully functional. Verify door locking, unlocking, and any other integrated features work as intended. </font></li> <li><font size="3">Step 10: Store a Spare Remote in a Safe Place Keep a backup, fully programmed remote in a secure location in case your primary fob is lost or stops working.</font></li> </ul>
