Keys

Almost all modern cars require a transponder key or fob to operate, providing security and anti-theft protection.

It's costly to replace them if they become lost, so it's a good idea to have spares in your possession. You can also find replacement keys fobs at various online stores and in many brick-and mortar auto shops. But how do you know that the new key fob you bought is genuine? Do you know whether it was programmed for another car or if it is able to be reprogrammed for yours?

To program a new car keys, you must first verify that your car is running. Insert the key you want to reprogram into the ignition without turning it. There are only a couple of seconds before the car's system resets commands and leaves programming mode. For this reason, it is crucial to move quickly and not be able to wait between steps. Turn off the engine to stop this. Turn the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful. The door locks will go through a cycle.

Some newer cars use a rolling key system, which stops thieves from using stolen cars' key to open it. The feature is still vulnerable to a technique dubbed a replay attack.

Transponder chips are a typical feature of modern cars and are designed to prevent car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted.

The car is also programmed to shut down when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then turn it on.

The chip and the key are linked by the circuit board which includes an induction coil. When the key is put in the ignition it creates a magnetic field generated around the transponder. This produces a signal which gets absorbed by the coil, which then transmits it to key's identification number. The key's identification number is then sent back to the car and the engine is started when the identification number is in line with.
