Keys
Modern cars require a transponder keys to operate. This gives security and anti-theft protection.

You will also find replacement key fobs in various online stores and in many brick-and mortar auto shops. How can you be sure that the key you purchased is authentic? Do you know whether the unit has been programmed to work with another vehicle or if it could be programmed differently?
If you want to program an entirely new key first, you need to ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. You only have a couple of seconds before the car's system resets commands and then exits programming mode. It is essential to move quickly and don't wait between each step. To prevent this from happening, turn off the engine. Switch the key from "on" to "off" to test the system. There should be a chime indicating that the process was successful. The door locks will go through a cycle.
Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique known as replay attacks that allows thieves to record the signal received from the vehicle's key fob, then reproduce it to unlock the car.

Transponder chips
Car keys that feature transponder chips need special reprogramming to work. While any hardware store can cut keys for you, the main issue is how to integrate it with your specific car. The key you reprogrammed needs to be compatible with the exact identification number of your car or else it won't be able to start the engine.
Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is put into the ignition. The car detects the signal and starts the engine only if it matches the original that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it.
A circuit board with an induction coil that connects the chip to the key. When the key is inserted into the ignition it creates a magnetic field around the transponder. This produces a signal which gets taken up by the coil, which sends it to the key's identification number. The key's ID number is then sent back to the vehicle and if it matches, the engine will start.
There are many ways to program a transponder, however each requires a special tool. These tools can be bought on the internet or at most auto locksmiths. These tools are not cheap but are essential to program your car's chip.
You may also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this case, make sure that the key has not been damaged or that the transponder is not altered in any way. To do this, you'll need a scanner or a computer equipped with a USB port to scan the chip and determine its identity.
