No. The suburban didn't get a transponder key until 2007.
A transponder ignition key is a type of car key that contains a small chip, or transponder, embedded within it. This chip communicates with the vehicle's ignition system, allowing the engine to start only when the correct key is detected. This technology enhances vehicle security by preventing unauthorized access, as a standard key without the transponder will not start the engine. Transponder keys are commonly used in modern vehicles for improved anti-theft protection.
I don't program your transponder key. Try taking it back to a garage of the same type as your car e.g ford and they may be able to provide some help.
Locksmiths have transponder detectors that read if a transponder is active within a key. The device we have is called "TD3AII Transponder Detector" by Ilco.
Most General Motors built cars are now using the PK3 Transponder key.

The 2003 GMC Envoy typically uses a standard ignition key without a chip. However, some models may be equipped with a transponder key system, which includes a chip for added security. It's best to check the owner's manual or consult a dealership to confirm the specific key type for your vehicle.

The dealership can generally program a new transponder key based on the VIN. Most good locksmiths can reproduce the key, but would need the original to do so.
A Toyota Matrix transponder key is factory programed. At times this programing can fail. It is a quick process for the dealership to reprogram the key. A lost key and transponder will cost approximately $100 to replace depending on model.
The circuitry for the door lock/unlock may go bad, but the transponder won't be affected. Meaning, you may have to manually open the door lock using the emergency key, but the Key fob can still be used to turn on the ignition. The transponder is a passive RFID chip that gets "queried" when the ignition is engaged. This is the same type of technology used on pets for tracking pets.
