GMC Key Programming Procedure
Procedure for Programming GMC 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.
Every GMC car comes with a simple process for programming the car’s immobilizer keys. The GMC car models are shown below:

About GMC
GMC, formerly the General Motors Truck Company or the GMC Truck & Coach Division (of General Motors Corporation), is a truck and utility vehicle division of the American automaker General Motors (GM). GMC currently produces SUVs, pickup trucks, vans, and light-duty trucks for the premium market. GMC previously manufactured fire trucks, ambulances, heavy-duty trucks, military vehicles, motorhomes, transit buses, and medium-duty trucks.
While many GMC and Chevrolet trucks share mechanical components, GMC is positioned as a premium alternative to the mainstream Chevrolet brand, with luxury vehicles such as the Denali series and the electric, off-road Hummer EV series. GMC vehicles are almost always sold alongside Buick vehicles at joint dealerships in North America, allowing the same dealer to market both upscale cars and trucks.
GMC was founded in 1900 in Detroit as the Grabowsky Motor Company by brothers Max (1874-1946) and Morris Grabowsky, and renamed Rapid Motor Vehicle Company in 1902 when the brothers relocated operations to Pontiac, Michigan. William C. Durant took over the Rapid Motor Vehicle Company in 1909 and made it a subsidiary of his General Motors Company. Durant took over Reliance Motor Car Company, another early commercial vehicle manufacturer, in 1908. General Motors formed the General Motors Truck Company in 1911, incorporating Rapid and Reliance. The names Rapid and Reliance were dropped in 1912 in favor of “GMC.” All General Motors truck production was consolidated at Pontiac, Michigan’s former Rapid Motor Plant 1.
GMC had three manufacturing plants, one in Pontiac, Michigan, one in Oakland, California, and one in St. Louis, Missouri.
A GMC truck drove from Seattle to New York City in thirty days in 1916, and a 2-ton GMC truck drove from New York to San Francisco in five days and 30 minutes in 1926. During World War I, the company produced the Model 16 3/4-ton truck, as well as 1-ton troop carriers and aviation support vehicles, and by 1918, more than 90% of GMC truck production was for military use. During the war, GMTC supplied the US government with a total of 8512 trucks, earning it a Distinguished Service Award. During WWII, GMC Truck manufactured 600,000 trucks for use by the United States Armed Forces.
GMC trucks were exported to Japan in 1923 to aid in the recovery and reconstruction following the Great Kant earthquake, and the company continued to supply vehicles as the transportation infrastructure was rebuilt. Prior to the earthquake, the majority of Japan’s commerce and people were transported by wooden carts and government-owned railroads, which were severely damaged when the train tracks were twisted beyond use. Autonomous trucks were far more effective in reaching severely damaged areas.
