Keys

Most modern vehicles require some kind of transponder key or fob to operate, providing security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with the car key programming and cutting's systems and specific model. It's expensive to replace them if they become lost, so it's best to have spares in your possession.

You have just a few minutes before the system resets all commands and exits the programming mode. It is important that you be quick and don't wait between each step. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a chime to indicate that the process was successful.

Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the vehicle. The feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and later reproduce the signal from the key fob of the vehicle to unlock the car.

The key needs to be programmed to match the exact identification number on your car, or else it won't start.

Transponder chips, used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is inserted in the ignition. The car is able to detect the signal and starts the engine only if the signal is in line with the one programmed in the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then start it.

The key and the chip are connected via the circuit board which includes an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This produces a signal which gets taken up by the coil, which then transmits it to key's identification number. The key's identification number is transmitted back to the car and the engine will start when the identification number matches.
