The tool initiates a Power Glitch or Fault Injection attack. It sends voltage spikes to the processor to make it expose protected memory. This takes 2 to 5 minutes. Do not interrupt this process. If the car goes into "Eco mode," restart.
The NCKReader connects via USB to a Windows laptop (Windows 7 or 10, 32-bit recommended). The device draws power from the USB port, but for "Samlock" extraction, you often need to connect external power leads to the vehicle's battery (12V) to stabilize the MCU during brute-force steps. nckreader samlock
In essence, the is a man-in-the-middle attack device. It sits between the vehicle’s immobilizer control unit and the engine ECU, listening to the data bus traffic to calculate the unique PIN code required to program a new key. Part 2: The Core Functionality – Why You Need It Modern vehicles do not allow you to simply cut a key and turn the ignition. You must program a cryptographic transponder chip to match the Body Control Module (BCM). To do this, you need the vehicle’s "Secret Code" (usually a 4-to-8-digit PIN). The tool initiates a Power Glitch or Fault Injection attack
The market is flooded with fake NCKReaders. A genuine Samlock unit costs between €150 and €300. Clones often fail on "Secure Lock" calculations, returning a garbage PIN (FFFF or 0000) which will lock the immobilizer for 15 minutes after 3 failed attempts. Do not interrupt this process
On Renault MED17.3.2 ECUs, the "Samlock unlock" procedure requires writing a patched bootloader. If the USB cable disconnects or the car battery voltage dips below 11.5V during the write, the ECU will become bricked. Recovery requires desoldering the flash chip (expensive).
