No, not any of the Saturn ION's manufactured by GM have chip keys, regardless of the model year.
2003 Saturn Ion clunking when breaking
Saturn Ion was created in 2003.
The 2007 Saturn Ion does not use a traditional transponder chip in the key like many modern vehicles. Instead, it typically uses a standard metal key for ignition. However, some models may have an optional keyless entry system, but this does not involve a chip in the ignition key itself. Always check your owner's manual or consult a dealer for specific information regarding your vehicle's key system.
