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

You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. How can you ensure that the one you bought is genuine?

If you're looking to program a new key first, you need to ensure that your vehicle is on and running. Insert the key you wish to reprogramme into the ignition, but don't turn it. There are only just a few seconds before the car's system reverts the commands and leaves programming mode. It is crucial to move quickly and don't wait between each step. To avoid this happening, turn off the engine. You can check the car's security system by turning the key to the "on" position and back to the "off" position.

Certain newer vehicles have rolling key technology that keeps thieves from using stolen cars' key to start it. The technology is still susceptible to a technique known as replay attack that allows thieves to record the signal received from the key fob of the car and reproduce it later to open the car.

Transponder chips
Car keys with transponder chips require special reprogramming to work. While any hardware store can cut keys for you, the main challenge is making it function in conjunction with your particular car. A reprogrammed key will need to be compatible with the specific identification number of the vehicle otherwise it won't even start the engine.

This makes it difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.
A circuit board that has an induction coil connects the chip to the key. When the key is inserted into 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 key's identification number is transmitted back to the car and the engine is started if the identification number matches.
