There are just a few minutes before the system will reset all commands and then exits the programming mode. For this reason, it is crucial to move quickly and not wait between steps. Stop the engine to stop this. Switch the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will be able to cycle.

The chip is a microcircuit that emits a radio frequency signal when the key is inserted into the ignition. The car detects the signal, and starts the engine only if it matches the original that was programmed into the vehicle. The car key reprogrammed is also programmed to shut down when it detects an incorrect frequency. This makes it more difficult for novice car thefts to wire a vehicle hot and then turn it on.

A circuit board equipped with an induction coil connects the key to the chip. When the key is placed in the ignition it creates an electric field around the transponder. This generates a signal, which is received by the coil and sent to the key's identification. The ID number of the key is transmitted back to the vehicle, and if it is in line with the engine will start.
