Keys
Most modern vehicles require a transponder key or fob in order to work, which provides security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. They are costly to replace in the event of loss and you should keep extras handy. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you ensure that the one you purchased is authentic? Do you know whether the unit has been programmed to work with a different vehicle, or if it can be programmed again?
To program a new car keys, you must first verify that your car is running. Insert the key you wish to program into the ignition without turning it. There are only a few seconds left before the system will reset all commands and then exits the programming mode. It is important that you be quick and don't be patient between each step. Shut off the engine to prevent this. You can test the system of your car by turning the key to the "on" position and then back to the "off" position. The door locks should be able to cycle, and you will hear a chime signalling that the process was successful.
Certain newer vehicles have rolling key technology, which stops thieves from using a stolen car's key to open it. The technology is still susceptible to a technique dubbed replay attacks, which allows thieves to record the signal from the key fob of the car and then replicate it to unlock the car. To combat this, manufacturers added a security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Some manufacturers also use special encryption on their key fobs which are not decoded by a simple program. You should only attempt this method if you have experience is with electronics. Refer to the manual for your car or go to the website of the manufacturer for information on how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Car keys that feature transponder chips require special programming to function. While any hardware store can cut keys for you, the real challenge is making it function to work with the specific car you own. The key must be programmed to match the exact identification number on your car, otherwise it won't be able to start.
Transponder chips, which are used to prevent car theft are a standard feature of modern automobiles. The chip is a microcircuit that emits a radio frequency signal when the key is put in the ignition. The car then scans for the signal and then starts the engine if it is in line with the original signal that was programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it much harder for novice car thieves to wire a vehicle and then start it.
The key and the chip are linked by an electronic circuit board that contains an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This creates a signal which is taken up by the coil and sent to the key's identification number. The ID number of the key is then sent back to the vehicle, and if it is in line with the engine will begin to run.

To do this, you can use scanners or computers with a USB port to read the chip and determine its identity.
