What is a Certification ECU on a smart-key Toyota or Lexus?
It's the separate immobilizer module (often called the smart key ID box, usually an 89784-series unit) that authenticates your keys to the smart-key system. It stores the encrypted key data the car checks before it will start.
Will my existing keys still work after the clone?
Yes. We copy your original immobilizer/key data onto the donor box, so your already-programmed smart keys are recognized exactly as before - no re-keying or AKL relearn needed.
