To program a new car keys, you must first verify that your car is running. Insert the key that you'd like to reprogramme into the ignition, but don't turn it. You have only a few seconds left before the system will reset all commands and leaves the programming mode. For this reason, it is important to be quick and not be able to wait between steps. To prevent this from happening, turn off the engine. Change the key from "on" to "off" to test the system. There should be a chime signalling that the procedure was successful. The door locks will go through a cycle.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to start the vehicle. This feature is still susceptible to a technique known as replay attack. It allows thieves to record and later reproduce the signal from the car key fob to unlock the car. To stop this, manufacturers introduced the security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys, which cannot be decoded by an ordinary program. You should only attempt this method if your previous experience is in electronic devices. It is a good idea to refer to your car's owner manual or search for the manufacturer online, as these steps vary by car model.

Car keys with transponder chips require a specific reprogramming to function. Any hardware store can offer you a new car key, but the real challenge is in making it work with your vehicle. A reprogrammed key 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, used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit which transmits a radio frequency signal when the key is placed in the ignition. The car detects the signal, and starts the engine only if the signal matches the original that was programmed in the vehicle. The car will also shut down if a frequency is invalid. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then turn it on.
A circuit board with an induction coil connects the key to the chip. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal, which is received by the coil and sent to the key 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 variety of methods to program a key transponder, but all of them require the use of a specific tool. You can buy these tools on the internet or at many automotive locksmiths. These tools aren't cheap but are essential to program your car's chip.
