You have only a few seconds before the system resets all commands and exits the programming mode. Therefore, it is essential to move fast and not be able to wait between steps.

Transponder chips

Transponder chips are a common feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is placed. The car then detects the signal and begins the engine in case it matches the original frequency that was programmed into the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it more difficult for thieves who aren't experienced to hot-wire a vehicle and then turn it on.
A circuit board that has an induction coil connects the key to the chip. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal that gets absorbed by the coil, which sends it to the key's identification number. The ID number of the key is sent back to the vehicle and if it matches the engine will start.
