Keys

Nearly all modern vehicles require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to function with your car's systems and the specific model. They are costly to replace if lost and it is recommended to keep spare keys in the car. You can also find replacement keys fobs in various online stores and in a variety of brick-and-mortar automotive shops. How can you know that the one you purchased is authentic?

This feature is still vulnerable to a method known as a replay attack that allows thieves to record the signal received from the key fob on the vehicle, then reproduce it to unlock the car. To counter this, manufacturers have introduced an additional security feature known as the CAN bus protocol to prevent attacks on hacking.

Transponder chips

Car keys with transponder chips require a special reprogramming to work. Any hardware store can offer you an entirely new car key, but the real challenge lies in integrating it with your car. The key must be programmed to match the exact identification number on your car, otherwise it won't be able to start.

Transponder chips, which are used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is placed into the ignition. The car detects the signal and begins the engine only if the signal is in line with the original one that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it much harder for thieves who are not experienced to wire a vehicle and start it.

A circuit board equipped with an induction coil that connects the key to the chip. When the key is inserted into the ignition it creates an electric field around the transponder. This generates a signal that is received by the coil and sent to the key's identification number. The key's identification number is transmitted back to the car, and the engine starts if the identification number matches.

To do this, you can use scanners or a computer with an USB port to read the chip and determine its identity.
