You will only have a couple of seconds before the car's system reverts the commands and then exits programming mode. This is why it is essential to move quickly and not pause between steps.

Transponder chips, used to stop theft of cars are a standard feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed.

This makes it much more difficult for thieves who are not experienced to connect a vehicle with hot wires and then start it.

A circuit board with an induction coil connects the chip to the key. When the key is placed in the ignition, a magnetic field is generated around the transponder. This generates a signal that gets absorbed by the coil, which transmits 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.
