Read the first 7 High-Security Automotive Keys flashcards as text

  1. Which Honda/Acura transponder system introduced the 46 chip (PCF7936) and requires an OBD bypass or EEPROM dump to clone because it is crypto-protected?

    Answer: Honda Ignition Security System (HISS)

    Honda's HISS (Honda Ignition Security System) on motorcycles and the similar system on cars uses crypto-locked transponders that typically require OBD tools or EEPROM work to add new keys.

  2. A locksmith needs to program a new key to a 2015 Toyota Camry with no working keys present. Which approach is most likely required?

    Answer: Using a professional key programmer with OBD PIN extraction or smart EEPROM bypass

    Toyota's 'all keys lost' scenario requires a professional device to extract the immobilizer PIN from the ECU via OBD or EEPROM, then program new keys into the system.

  3. What is the function of the 'dealer seed key' in some BMW EWS systems?

    Answer: A special service key used to authorize new key programming sessions

    In BMW EWS systems, a dealer seed key (or ISN code derivation) is used to authenticate the programming session before new keys can be registered to the EWS module.

  4. When using an automotive key programmer to perform an EEPROM read, the technician must physically access which component?

    Answer: The BCM, ECM, or immobilizer control module's memory chip

    EEPROM reading requires direct access to the memory chip inside the immobilizer or ECU module, typically involving removal of the module and soldering or clip-on probes.

  5. Which frequency do most North American automotive remote key fobs operate on?

    Answer: 315 MHz

    Most North American vehicles use 315 MHz for their remote keyless entry (RKE) systems, while European vehicles typically use 433.92 MHz.

  6. A locksmith encounters a Subaru with an immobilizer that uses a 4D60 transponder. What generation of Subaru immobilizer is this associated with?

    Answer: Second generation using a crypto-locked ID60 transponder

    The 4D60 (also known as ID60) is a second-generation crypto transponder used by Subaru, which is more secure than the earlier fixed-code 4D chips.

  7. What is 'key relearning' (also called 'key registration') in the context of high-security automotive systems?

    Answer: The process by which the vehicle's immobilizer stores a new transponder's credentials

    Key relearning/registration is the procedure where the vehicle's immobilizer ECU is instructed to recognize and save the cryptographic identity of a new transponder.
