Keys
Most modern vehicles require some kind of transponder key or fob in order to operate, ensuring security and protection against theft. These keys must be programmed to your particular vehicle and its systems by an authorized dealer or locksmith.

Can you tell whether the unit has been programmed to work with a different vehicle or if yours can be programmed again?
If you are planning to program a new key first, you need to make sure that your car is on and running. Insert the key you want to reprogram into the ignition without turning it. There are just a few minutes before the system resets all commands and leaves the programming mode. For this reason, it is important to move quickly and not pause between steps. To prevent this from happening, shut off the engine. Switch the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a chime signalling that the procedure was successful.
Certain cars with more modern technology have rolling key technology, which prevents thieves from using a stolen vehicle's key to open it. This feature is still susceptible to a technique dubbed a replay attack. It allows thieves to record and later reproduce the signal received from the vehicle key fob to open the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to prevent attacks on hacking.
Certain manufacturers have a unique encryption on their keys, which cannot be decoded by a simple program. These types of vehicles will need to be programmed by a professional. Therefore, you should only attempt this procedure only if you've worked with electronic devices. Refer to the manual for your car or go to the website of the manufacturer to find out how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming in order to work. While any hardware store can cut keys for you, the main problem is to make it work with your specific car. A reprogrammed key will need to match the specific identification number of your car otherwise it won't even start the engine.
Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit that transmits a radio frequency signals when the key is placed in the ignition. The car can detect the signal, and starts the engine only if it matches the original that was programmed in the vehicle. The car also shuts down if a frequency is invalid. This makes it more difficult for novice car thefts to hot-wire a vehicle and then start it.
A circuit board equipped with an induction coil connects the key to the chip. When the key is inserted into the ignition it creates an electromagnetic field around the transponder. This generates a signal, which is received by the coil before being sent to the key identification number. The ID number of the key is transmitted back to the vehicle, and if it matches the engine will begin to run.
There are a variety of methods to program a key transponder, however all of them require the use of a specific tool. You can purchase these tools online or from most locksmiths for cars. These tools aren't cheap but are essential for programming your car's chip.
You can also use an reprogrammable key that was previously programmed for a different vehicle. In this case, make sure that the key has not been damaged or the transponder is not altered in any way. To accomplish this, you'll need scanners or computers equipped with an USB port to identify the chip and establish its identity.
Reprogramming the transponder is a straightforward procedure, but it requires specialized software. It also requires the use of a scanner. If you're a beginner you should seek out the help of an auto locksmith. You should also avoid buying second-hand keys as they're probably already programmed and will not work with your car.
