The door locks should be able to cycle, and you will hear a sound that indicates that the process was successful.

Certain cars with more modern technology have rolling key technology, which keeps thieves from using stolen cars' key to start it. This feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and then duplicate the signal generated by the vehicle key fob to unlock the car. To combat this, manufacturers have added a security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.

Transponder chips

Car keys with transponder chips require special programming to function. Any hardware store can make you an entirely new car key, however the real challenge lies in implementing it to your car. The key you reprogrammed needs to be compatible with the exact identification number of your car otherwise it won't even start the engine.

Transponder chips, which are used to protect cars from theft, are a common feature of modern automobiles. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then scans for the signal and then starts the engine if it matches the original one that was programmed into the vehicle. The car is also programmed to shut down if it detects an invalid frequency. This makes it difficult for thieves with no experience to hot-wire a vehicle and then turn it on.

The key and the chip are linked by an electronic circuit board that contains an induction coil. When the key is placed in the ignition, a magnetic field is created around the transponder. This generates a signal that is taken up by the coil, which sends it to the key's identification number. The key's identification code is returned to the car and the engine will start if the identification number matches.

Reprogramming the transponder is a straightforward procedure, but it requires specialized software. It also requires a scanner tool. If you're just beginning it is recommended to seek out the help of an auto locksmith. Also, avoid buying second-hand keys, since they are likely already programmed and won't work with your vehicle.
