Transponder Chip

The key fob of a Hyundai is equipped with a specific electronic component. The chip sends an indication to the car, telling it to unlock or start. This type of key, also known as an "immobilizer" or "chip key" is now a the norm for all cars of recent years. It also helps in preventing theft.

Immobilizer

The immobilizer is a security device in your vehicle. Its purpose is to deter thieves from opening your car by verifying that the key or fob you are using has the correct code.

The immobilizer will detect these signals when you insert the key and compare them to the codes that are embedded in the ECU of your vehicle. If the codes don't match, the ECU won't be able to activate your spark plugs or the fuel system and stop the engine from beginning.

To crack the immobilizer in a vehicle, require a specific device that can transmit signals to the transponder and read the data. Then, you can use the information that you've gathered to gain access the CAN bus which is the vehicle's internal communication system. Once you've access to the CAN bus, you can read the messages that the immobilizer components exchange as well as deactivate the engine control module or body control module.
