Stop Car Theft at the Chip Level

Automotive-grade immobilizer transponder ICs that protect millions of vehicles worldwide.

Vehicle theft costs the global automotive industry billions annually. Traditional mechanical keys are easily duplicated. Modern vehicles need cryptographic security embedded at the silicon level.

Rolling Code Cryptography — Impossible to Clone

Silicon Craft’s SIC61 series immobilizer transponder ICs use rolling code cryptography to prevent key cloning. Each authentication generates a unique code — making duplication nearly impossible. Our ICs meet the rigorous AEC-Q100 standard for automotive-grade electronic components.

How It Works

  1. Smart Key Communication: The smart key contains an RFID transponder with a rolling code system synchronized to the car’s ECU.
  2. Secure Authentication: When the driver inserts the key, the ECU sends a challenge signal. The key returns an encrypted response.
  3. Engine Start: The engine starts only when the cryptographic handshake succeeds.
