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.

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). nckreader samlock

Older versions of NCKReader Samlock required an annual activation to update the "SAM_Key.dll" file. Newer hardware (v4.5 and up) offers lifetime offline calculation, but costs double.

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.

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.

Launch the NCKReader software. Select "Samlock Mode." The tool will read the BSL (Bootloader) version of the target ECU. If the ECU responds with "Samsung Lock Active," you know extraction is possible.
