Keyless Entry Remote Programming Instructions – 2002 Oldsmobile Alero

Important Notice: The 2002 Oldsmobile Alero does not support onboard programming for keyless entry remote fobs. Programming must be performed using professional diagnostic equipment by a qualified technician.

Programming Procedure:

• Step 1: Contact a certified automotive technician or authorized service provider who is experienced with remote key fob programming and has access to vehicle-compatible diagnostic tools.
• Step 2: Confirm that the technician uses software that can securely interface with your vehicle’s onboard electronic systems to program the new remote.
• Step 3: If the vehicle is drivable, consider bringing it to the service location. This can help reduce costs compared to requesting mobile service.
• Step 4: Schedule an appointment in advance to ensure the technician is available and properly equipped for your specific model.
• Step 5: Bring all existing remotes to the appointment. In many systems, all remotes must be programmed during the same session to remain functional.
• Step 6: At the service location, the technician will connect a diagnostic device to the vehicle’s onboard diagnostic port, typically located under the dashboard.
• Step 7: Using the diagnostic software, the technician will initiate the programming process to register the new keyless entry remote with your vehicle’s system.
• Step 8: After programming, the technician will test all remote functions—including locking, unlocking, trunk release, and panic alarm—to ensure everything works correctly.
• Step 9: Personally test each remote before concluding the service to confirm successful programming.
• Step 10: Keep spare remotes in a safe location, and consider having an extra remote programmed as a backup.
