Jeep Key Programming Procedure
Procedure for Programming Jeep Keys
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.

About Jeep
Jeep is a brand of American automobiles that is now owned by the multinational corporation Stellantis. Jeep has been a part of Chrysler since 1987, when Chrysler purchased the Jeep brand as well as its remaining assets from its previous owner, American Motors Corporation (AMC).
Jeep’s current product lineup is entirely comprised of sport utility vehicles – both crossovers and fully off-road capable SUVs and models, as well as one pickup truck. Previously, Jeep’s lineup included other pick-ups, small vans, and a few roadster models. Some Jeep vehicles, such as the Grand Cherokee, enter the luxury SUV segment, which the 1963 Wagoneer is credited with pioneering. Jeep sold 1.4 million SUVs worldwide in 2016, up from 500,000 in 2008, with two-thirds of those sold in North America, and was Fiat-best-selling Chrysler’s brand in the United States during the first half of 2017. Over 2400 dealerships in the United States alone have franchise rights to sell Jeep-branded vehicles, and if Jeep were spun off into a separate company, it is estimated to be worth between $22 and $33.5 billion—slightly more than FCA as a whole (US).
Prior to 1940, the term “jeep” referred to a U.S. Army slang for new recruits or vehicles, but the World War II “jeep” that went into production in 1941 specifically tied the name to this light military 4×4, making them arguably the oldest four-wheel drive mass-production vehicles now known as SUVs. During World War II and the postwar period, the Jeep became the primary light four-wheel-drive vehicle of the United States Armed Forces and the Allies. Following the war, the term became widely used around the world. According to Doug Stewart, “the spartan, cramped, and unstintingly functional jeep became the ubiquitous World War II four-wheeled personification of Yankee ingenuity and cocky, can-do determination.” It inspired the creation of civilian analogs such as the original Series I Land Rover. Since then, many Jeep variants serving similar military and civilian roles have been designed in other countries.
Since Willys–Overland began production of the first CJ or Civilian Jeep branded models in Toledo, Ohio, the Jeep marque has been headquartered there. It has been replaced by the conceptually consistent Jeep Wrangler series, which has been in production since 1986. The Wrangler, with its solid axles and open top, has been dubbed the Jeep model that is as central to the brand’s identity as the 911 is to Porsche.
At least two Jeep models (the CJ-5 and the SJ Wagoneer) had three-decade production runs in a single body generation.
Lowercase “jeep” is still used as a generic term for vehicles inspired by the Jeep that are suitable for use on rough terrain. In Iceland, the word Jeppi (derived from Jeep) has been used since WWII and is still used for any type of SUV.
