Keys

Most modern cars require a transponder keys to operate. This is a security feature and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with the car's systems and the specific model. They can be costly to replace in the event of loss, so you should have spares in your car. You can also find replacement key fobs at various online stores and in many brick-and mortar auto shops.

To program a new car key first make sure that your car is running. Insert the key you want to program into the ignition, but do not turn it. There are only a couple of seconds before the car's system resets commands and then exits programming mode. It is important that you move quickly and don't be patient between each step. To avoid this happening, turn off the engine. You can test the car's system by turning the key to the "on" position and back to the "off" position.

Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the car. This feature is still vulnerable to a technique known as replay attack, which allows thieves to record the signal received from the key fob on the vehicle, then reproduce it to unlock the car.

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

Transponder chips are a standard feature of modern cars and are designed to stop car theft. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car then recognizes the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it much harder for novice car thieves to hot wire a vehicle and start it.

The key and the chip are linked by a circuit board that includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This creates a signal that gets absorbed by the coil, which sends it to the key's identification number. The key's ID number is transmitted back to the vehicle, and if it is in line with the engine will start.
