Keys
Almost all modern cars require a transponder fob or transponder keys to work, which provides security and anti-theft protection.

But how do you know that the new one you have bought is genuine? Do you know whether the unit is programmed to work with another vehicle or if yours can be programmed differently?
To program a new car key, first make sure that your car is running. Insert the key you wish to reprogram into the ignition without turning it. There are just a few minutes before the system will reset all commands and exits the programming mode. It is important that you move quickly and do not delay between each step. Turn off the engine to stop this. Change the key from "on" to "off" to test the system. The door locks should cycle and you will hear a chime to indicate that the process has been successful.

A key that has been reprogrammed will need to match the specific identification number of your car, or it won't start the engine.
Transponder chips are a typical feature in modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car can detect the signal, and starts the engine only if the signal matches the original one that was programmed in the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it much harder for novice car thieves to hot wire a vehicle and then start it.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This produces a signal which is absorbed by the coil, which transmits it to the key's identification number. The ID number of the key is transmitted back to the vehicle and if it matches the engine will begin to run.
