You will only have just a few seconds before the car's system reverts the commands and then exits programming mode. Therefore, it is essential to move quickly and not be able to wait between steps.

Transponder chips are a standard feature of modern cars and are designed to stop car theft. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then scans for the signal and begins the engine if it is in line with the original one that was programmed into the vehicle. The car is also programmed so that it will stop if it detects an invalid frequency. This makes it more difficult for thieves who are not experienced to wire a vehicle and then start it.
A circuit board equipped with an induction coil connects the chip to the key. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal that is absorbed by the coil, which then transmits it to key's identification number. The key's identification code is transmitted back to the car, and the engine starts when the identification number is in line with.
