The majority of modern vehicles require a transponder key to operate. This is a security feature and protection against theft. The keys have to be programmed to your particular vehicle and its features by an authorized dealer or locksmith. They are costly to replace in the event of loss, so you should keep extras handy. You can also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. How can you be sure that the one you bought is authentic? Are you able to tell if the unit has been programmed to work with another vehicle or if yours can be programmed differently?
To program a new car key you must first verify that your vehicle is operating. Insert the key you want to reprogramme into the ignition, but do not turn it. There are only just a few seconds before the car's system reverts the commands and then exits programming mode. It is important that you move quickly and don't delay between each step. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should be able to cycle, and you will hear a chime signalling that the process was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the vehicle. This technology is still vulnerable to a technique known as replay attack that allows thieves to record the signal received from the key fob on the vehicle and reproduce it later to open the car.

Car keys with transponder chips require a specific reprogramming to function. While any hardware store can cut keys for you, the biggest problem is to make it work with your specific car. A reprogrammed key will need to match the exact identification number of the vehicle, or it won't start the engine.
Transponder chips, used to stop theft of cars, are a common feature of modern automobiles. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car then recognizes the signal and starts the engine if it is in line with the original frequency that was programmed into the vehicle. The vehicle is also programmed to shut down if it detects an invalid frequency. This makes it much harder for thieves who are not experienced to wire a vehicle and then start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition, a magnetic field is generated around the transponder. This creates a signal which is received by the coil before being sent 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 begin to run.
