Most modern cars require a transponder keys to operate. This is a security feature and anti-theft protection.

You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How do you ensure that the one you purchased is authentic? Do you know whether it was programmed for a different vehicle or if it could be reprogrammed for yours?
If you're looking to program a new key the first step is to ensure that your car is running. Insert the key that you wish to program into the ignition, but do not turn it. You have only a few seconds left before the system will reset all commands and then exits the programming mode. Therefore, it is important to move quickly and not pause between steps. Shut off the engine to prevent this. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. There should be a chime indicating that the process was successful. The door locks will be able to cycle.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique known as replay attacks, which allows thieves to record the signal of the vehicle's key fob and then replicate it to open the car. To prevent this, manufacturers have added security features known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also employ special encryption on their key fobs which are not decoded by an easy program. These kinds of cars require programming by a professional, so you should only attempt this process with someone who has experience with electronic devices.

Transponder chips
Car keys with transponder chips require a special programming to function. Any hardware store can offer you a new car key but the real challenge is in implementing it to your vehicle. The key must be programmed to match the exact identification code on your car, otherwise it won't be able to start.
Transponder chips, used to prevent car theft, are a common feature of modern automobiles. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car detects the signal, and starts the engine only if it matches the one programmed in the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it more difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.
The key and the chip are linked by the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field created around the transponder. This generates a signal that is absorbed by the coil and then transmitted to the key's identification number. The ID number of the key is sent back to the vehicle, and if it is in line with the engine will begin to run.
There are a variety of ways to program a transponder, however all of them require a special tool. These tools are available on the internet or at most auto locksmiths. These tools aren't inexpensive, but they are vital for programming your car's chip.
You can also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this case, make sure that the key isn't damaged or that the transponder is not altered in any way. To accomplish this, you can use scanners or a computer equipped with a USB port to read the chip and determine its identity.
Reprogramming the transponder key is simple, but it requires specialized software and a scan tool. If you're just beginning it is recommended to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys, since they are likely already programmed and won't work with your car.
