When no valid smart key is present it is not possible to start engine and also it might be not possible to diagnose other ECUs than PIC/SMK.Įngine must be turned off, start/stop pushbutton in OFF state. Please make sure you are purchasing smart keys from a trusted source. Used smart keys cannot be programmed to another car.
HYUNDAI SONATA 2017 SMART KEY HOLDER CODE
The feature can be found in Smart Key Code Saving control unit (PIC, SMKCODE). On these vehicles coding via SMARTRA operation will fail, it is necessary to use special dedicated smart-key control unit for this purpose. Some vehicles have contact-less (RFID) smart-key instead of mechanical key.
If you click on "No", the coding process is terminated and no more keys are added.Īfter successful completion of the operation, switch off the ignition for 10 seconds. Up to 4 keys can be coded.(some control units allow units up to 8 keys).
If you click "yes", HiCOM will ask you to insert the next key. You will be prompted whether you want to code another key. This key is coded after clicking on "Yes" button. Now you have the key in ignition in the ON position. You will be prompted to enter a 6-digit PIN code. Key coding procedure is available in control unit IMMO – Immobilizer from “ECU Programming/Coding” menu.Įngine must be turned off. Mechanical keys with RFID chip (non-proximity) Supported vehiclesįollowing list shows all vehicles for which is key teaching supported: Manufecture Vehicle PIN code can be obtained through service or through Hyundai dealer.
PIN code stands for of Product Identification Number code. The vehicle specific data are written into the transponder memory. The data of all transponder, which are valid for the vehicle, are stored in the ECM.ĭuring the key teaching procedure the transponder will be programmed with vehicle specific data. Only if the results are equal the engine can be started. The ECM carries out the check of ignition key by special encryption algorithm, which runs in the transponder and in the ECM in parallel. The immobilizer system consists of the ECM, the SMARTRA, the lamp and ignition keys with built-in transponder. The multiplexer is a part of ECM hardware. The ECM controls the communication either to SMARTRA or diagnostic equipment on K line by switching of a multiplexer and specific communication procedures. During communication of ECM and SMARTRA the K line of ECM cannot be used for communication. The SMARTRA communicates to a engine control module via a dedicated communications line (called W-Line, or Immo-Line).
HYUNDAI SONATA 2017 SMART KEY HOLDER SERIAL
This device is only an advanced interface, which converts the RF data flow (radio frequency of 125 kHz) of transponder into serial communication to ECM and vice versa. The SMARTRA does not carry out the check of validity of transponder or the calculation of encryption algorithm. The SMARTRA unit contains an integrated inductive antenna and electronics around the ignition lock assembly. The SMARTRA stands for SMARt TRansponder Antenna.
