Modern cars require a transponder key in order to operate. This provides security and anti-theft protection.

There are only a few seconds left before the system resets all commands and then exits the programming mode. It is important that you be quick and don't delay between each step. Stop the engine to prevent this. Change the key from "on" to "off" to test the system. The door locks should cycle, and you'll hear a sound that indicates that the process has been successful.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique dubbed replay attack that allows thieves to record the signal from the key fob of the car and then replicate it to open the car. To counter this, manufacturers have introduced a security feature called the CAN bus protocol to stop attacks on hacking.
Certain manufacturers have a unique encryption on their keys that can't be decoded with an easy program. You should only attempt this method if your previous experience is in electronic devices. Refer to the manual for your car or look up the website of the manufacturer for information on how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys with transponder chips need special reconfiguration to work. While any hardware store can cut a new key for you, the real issue is how to integrate it with your specific car. reprogramming key fob that has been reprogrammed will need to be matched with the exact identification number of your car or else it won't be able to start the engine.
Transponder chips, which are used to protect cars from theft are a standard feature of modern cars. The chip is a microcircuit that transmits a radio frequency signals when the key is placed into the ignition. The car detects the signal, and starts the engine only if the signal is in line with the original that was programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it much more difficult for thieves who are not experienced to connect a vehicle with hot wires and start it.
A circuit board with an induction coil connects the key to the chip. When the key is put in the ignition the magnetic field is generated around the transponder. This creates a signal that gets absorbed by the coil, which transmits 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 begin to run.
There are a few different methods to program a transponder key however, they all require an appropriate tool. These tools can be bought on the internet or at most auto locksmiths. These tools aren't cheap but are essential to program your car's chip.

To accomplish this, you'll need scanners or a computer with an USB port to read the chip and determine its identity.
