Keys

You will only have a few seconds before the car's system resets the commands and then exits programming mode. It is important that you move quickly and don't be patient between each step.

Certain newer vehicles have rolling key technology, which keeps thieves from using a stolen car's key to open it. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and then reproduce the signal from the car key fob to unlock the car.

Transponder chips

Car keys with transponder chips require special reprogramming to work. While any hardware store can cut keys for you, the main problem is to make it work in conjunction with your particular car. The key you reprogrammed needs to match the exact identification number of the vehicle, or it won't start the engine.

Transponder chips, which are used to prevent car theft, are a common feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car detects the signal and begins the engine only if the signal is in line with the one programmed in the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it harder for thieves who aren't experienced to wire a vehicle hot and then turn it on.

The chip and the key are linked by the circuit board which includes an induction coil. When the key is inserted into the ignition it creates a magnetic field around the transponder. This creates a signal that gets absorbed by the coil, which transmits it to the key's identification number. The ID number of the key is transmitted back to the vehicle and if it matches, the engine will start.
