The engine immobilizer is an anti-theft system that employs a keyfob with a digital code stored on it. When the keyfob comes into contact with the vehicle’s electronic management system or is inserted into the ignition switch, it transmits this “password” to it. If the user has the correct keyfob, the engine will start up.
The engine immobilizer is a safe method of discouraging thieves from stealing your car through hotwiring or traditional methods such as hammering the ignition with a screwdriver to force it to start. It’s like an extra layer of security on top of your car’s alarm.
St. George Evans and Edward Birkenbuel invented and patented the electric immobiliser/alarm system in 1919. When the ignition switch was turned on, current from the battery (or magneto) went to the spark plugs, allowing the engine to start or immobilizing the vehicle and sounding the horn. Each time the car was driven, the system settings could be changed. Modern immobiliser systems are automatic, which means the owner does not have to remember to turn it on.
Since January 1, 1998, all new cars sold in Germany have been required to have immobilizers, as have all new cars sold in the United Kingdom since October 1, 1998, in Finland since 1998, in Australia since 2001, and in Canada since 2007. Early models used a static code in the ignition key (or key fob) that was recognized by an RFID loop around the lock barrel and checked for a match against the vehicle’s engine control unit (ECU). If the code is not recognized, the ECU will prevent fuel from flowing and ignition from taking place. Later models employ rolling codes or advanced cryptography to prevent code copying from the key or ECU.
Every TOYOTA car comes with a simple process for programming the car’s immobilizer keys. The TOYOTA car models are shown below:
Toyota Motor Corporation is a Japanese multinational automaker based in Toyota City, Aichi, Japan. Kiichiro Toyoda founded it and incorporated it on August 28, 1937. Toyota is one of the world’s largest automakers, producing approximately 10 million vehicles per year.
The company began as a spinoff of Toyota Industries, a machine manufacturer founded by Kiichiro’s father, Sakichi Toyoda. Both companies are now part of the Toyota Group, one of the world’s largest conglomerates. While still a division of Toyota Industries, the company produced its first product, the Type A engine, in 1934, and its first passenger car, the Toyota AA, in 1936.
Following World War II, Toyota benefited from Japan’s alliance with the United States to learn from American automakers and other companies, giving rise to The Toyota Way (a management philosophy) and the Toyota Production System (a lean manufacturing practice), which transformed the small company into an industry leader and became the subject of many academic studies.
Toyota took advantage of a rapidly growing Japanese economy in the 1960s to sell cars to a growing middle-class, resulting in the development of the Toyota Corolla, which went on to become the world’s best-selling automobile. The booming economy also enabled Toyota to expand internationally, allowing it to become one of the world’s largest automakers, the largest company in Japan, and the ninth-largest company in the world by revenue by December 2020. Toyota was the world’s first automaker to produce more than 10 million vehicles per year, a record it set in 2012, when it also announced the production of its 200 millionth vehicle.
Toyota was lauded for being a pioneer in the development and sale of more fuel-efficient hybrid electric vehicles, beginning with the 1997 introduction of the Toyota Prius. The company now sells over 40 hybrid vehicle models worldwide. However, the company has recently been accused of greenwashing for its skepticism of all-electric vehicles and its focus on the development of hydrogen fuel cell vehicles, such as the Toyota Mirai, a technology that is more expensive and has lagged far behind electric batteries.
Toyota Motor Corporation manufactures vehicles under five brands: Daihatsu, Hino, Lexus, Ranz, and Toyota. The company also owns 20% of Subaru Corporation, 5.1 percent of Mazda, 4.9 percent of Suzuki, 4.6 percent of Isuzu, 3.8 percent of Yamaha Motor Corporation, and 2.8 percent of Panasonic, as well as stakes in vehicle manufacturing joint ventures in China (GAC Toyota and FAW Toyota), the Czech Republic (TPCA), India (Toyota Kirloskar), and the United States (MTMUS)
Toyota’s stock is traded on the London Stock Exchange, the Nagoya Stock Exchange, the New York Stock Exchange, and the Tokyo Stock Exchange, where it is part of the Nikkei 225 and TOPIX Core30 indices.
