How to Program a Car Key

Modern cars come with more than just a single key to start the engine, they also come with a remote that can lock and unlock doors. These key fobs must be programmed to function.

How do you program a key

Up until the turn of the 21st century most cars used basic key systems. Keys were made of metal and had grooves to match the internal components of the ignition cylinder. As technology advanced, more and more car makers began to mix electronic and physical protocols to avoid theft. These key systems are referred to as transponder keys or chip keys and are designed to make it difficult for thieves to start the vehicle.

The key chips inside the keys have a unique serial number that transmits a signal to the receiver inside of your car. The signal is compared with a code in the car's computer when it is received. If the codes are compatible, then the car will start. If not, it won't start at all. This is one of the main reasons you should keep a spare key in your vehicle, especially if you have transponder-based systems.

This energy is absorbed into the chip and sends back the radio frequency signal, which includes an identification code that matches up to the unique digital serial number of the car's computer system. This helps prevent unauthorized attempts to start the car, because only a valid key can do so.

This technology is thought to be more secure than a conventional car key because it makes it difficult for thieves to "hot wire" the vehicle and then start it. But it's not foolproof, and thieves have discovered ways to deceive and thwart the system so that even vehicles with transponder keys are not immune from theft.
