Toyota Prius 2001-2003 Key Programming Procedure
The following are the key programming procedures for Toyota Prius for the year 2001 to 2003.
Fits (vehicles without red LED on original remote):
1. Start with key out of ignition, driver’s door is open all others closed and driver’s door is unlocked.
2. Insert key into the ignition (Do NOT Turn) and Pull key out.
3. Perform these steps within 40 seconds.
a. Using the power lock switch on the driver’s door, perform 5 lock/unlock cycles starting with lock. Use an even pace and try to go about one cycle per second (1 Cycle = 1 lock and 1 unlock).
b. Close, then open driver’s door.
4. Perform these steps within 40 seconds.
a. Using the power lock switch on the driver’s door, perform 5 lock/unlock cycles starting with lock.
Use an even pace and try to go about one cycle per second (1 Cycle = 1 lock and 1 unlock).
b. Insert the key in the ignition cylinder.
c. Turn the ignition to ON (Do NOT Start) then back to OFF once to program remote while retaining the original remote codes. Twice to erase all original codes and add new remote. Three times to check how many remotes are programmed or five times to erase all original codes.

About Toyota Prius
Automakers have been seeking for solutions to meet increasingly strict regulations for lower exhaust emissions and improved fuel mileage as a result of rising government pressure. Electric automobiles, such as GM’s EV1, were supposed to be the answer in the 1990s, but their range is restricted and they must be “plugged in” to be recharged. Because its exhaust by-product is essentially water vapor, hydrogen-fueled fuel cell automobiles will someday constitute the ultimate evolution of the automobile. However, fuel cell automobile technology is still in its infancy, and mass-produced fuel cell cars are yet a few years away.
Hybrid-electric vehicles are the best hope for now and the near future. A gasoline engine is combined with an electric motor in hybrid vehicles. Furthermore, because hybrids are still powered by gasoline, they do not need to be plugged in or recharged. In the case of the Toyota Prius, hybrid technology results in lower pollutants and higher fuel efficiency as compared to a conventional gasoline-powered vehicle. The only concern has been that a hybrid vehicle would never be useful as an actual car that people would want to purchase. Toyota has mostly allayed those anxieties with the Prius.
The Prius was introduced to the American market in 2001, but Toyota has been selling them in Japan since December 1997. When compared to previous Prius models, US versions have greater horsepower, more emissions equipment, and a more powerful battery pack that is simultaneously smaller and lighter.
In the United States, there are just three mainstream hybrid-electric automobiles on the market. There’s the Prius, the Insight, and the Civic Hybrid. Until recently, we thought the Prius was the greatest option because it was more adaptable than the two-seat Insight. The Civic Hybrid, on the other hand, is all-new for 2003, and in many ways, this “second-generation” hybrid vehicle outperforms the Prius. The Civic is our pick for a hybrid vehicle, however the 2003 Toyota Prius is also a viable option.
