The internet would have photos of 2001 Camry "smart" keys. They call it a keyed transponder (smart as in chipped) and non-transponder (not smart, no chip).

The ECU is programmed to the engine model, year, auto/manual trans, emissions spec met, etc.

A bigger issue when swapping engines of the same model is Toyota made changes over time. This may extend to having two different emissions model of the year as is in the California emission spec model and the Federal spec model. Some changes would require a different ECU. 2001 was the last US Camry to use the 2.2 four cylinder.

The 2001 had a returnless fuel system to the fuel rail, improved ign using pick up sensors, different cylinder head and intake manifold.
