There are only a few seconds before the car's system reverts the commands and exits programming mode. It is important that you move quickly and don't delay between each step.

The key you reprogrammed needs to be compatible with the exact identification number of your vehicle, or it won't start the engine.

Transponder chips are a standard feature in 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 starts the engine in case it matches the original signal that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it much more difficult for novice car thieves to wire a vehicle and start it.

A circuit board that has an induction coil connects the key to the chip. When the key is inserted into the ignition it creates a magnetic field around the transponder. This creates a signal which is absorbed by the coil and then transmitted to the key's identification number. The key's identification number is sent back to the car, and the engine starts when the identification number matches.
