You will only have just a few seconds before the car's system resets commands and then exits programming mode. It is important that you move quickly and do not wait between each step.

The key must be programmed to match the exact identification code on your car, or else it won't be able to start.

Transponder chips are a standard feature of modern cars and are designed to guard against car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted in the ignition. The car is able to detect the signal and begins the engine only if the signal matches the original that was programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it much harder for car thieves with no experience to hot wire a vehicle and then start it.

The key and the chip are connected by the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This produces a signal which is taken up by the coil, which sends it to the key's identification number. The ID number of the key is then sent back to the vehicle, and if it is in line with the engine will start.

There are many methods to program a transponder key however, all require a special tool. You can buy these tools online or at most locksmiths in the automotive industry. They are not cheap, but they are essential for programming the chip into your vehicle.

You may also use a resettable key that was programmed for another vehicle. In this case, ensure that the key has not been damaged or that the transponder isn't altered in any way. You can read the chip with a scanner, or a computer equipped with a USB connector.

It is recommended to contact an auto locksmith for assistance if you're a novice. Also, avoid buying second-hand keys, since they're likely to be programmed and will not work with your car.
