Keys
Nearly all modern vehicles require a transponder key or fob to operate, providing security and protection against theft.

You only have a few seconds before the car's system resets the commands and leaves programming mode. Therefore, it is important to be quick and not wait between steps. Shut off the engine to avoid this. Change the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a sound that indicates that the procedure was successful.
Some newer vehicles use rolling keys to keep thieves from using stolen keys to start the vehicle. This technology is still vulnerable to a method known as a replay attack which allows thieves to record the signal received from the key fob on the vehicle, then reproduce it to open the car.

Transponder chips
Car keys with transponder chips require a specific reprogramming to function. Any hardware store can make you a new car key, but the real challenge is in making it work with your car. A key that has been reprogrammed will need to match the exact identification number of your vehicle, or it won't start the engine.
Transponder chips, which are used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is placed in the ignition. The car then recognizes the signal and begins the engine if it is in line with the original signal that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and start it.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field around the transponder. This generates a signal, which is absorbed by the coil before being sent to the key identification number. The key's ID number is then sent back to the vehicle, and if it matches the engine will begin to run.

It's best to ask an auto locksmith for assistance for those who are new to the process. You should also avoid buying second-hand keys as they are likely already programmed and will not work with your car.
