Toyota / Lexus services we offer
All flat-priced, all 24-hour bench turnaround, all with flat-rate return shipping picked at checkout.

Toyota/Lexus Denso IMMO Off
Permanently remove immobilizer from Toyota + Lexus Denso ECUs — bench fix for swapped ECU, lost keys, or failed pairing.

Toyota/Lexus Certification ECU Clone
We clone your smart-key Certification ECU (ID box) to a donor so your push-to-start Toyota or Lexus recognizes its keys and starts.

Lexus Denso ECU Clone
We clone your original Lexus Denso engine ECU data onto a used/donor ECM so a replacement unit starts and runs in your car.

Toyota/Lexus Smart-Key AKL & Key Generation
Locked out of a push-to-start Toyota or Lexus with no working key? Mail in your Smart-Key / Certification ECU and we read the EEPROM on the bench and generate a working smart key so the car starts — no dealer, no tow.

Toyota/Lexus ECU Immobilizer Reset (Add Keys)
Older turn-key Toyota or Lexus with no master key? Mail in your engine ECU and we reset the immobilizer EEPROM on the bench and include a new cut transponder key ready to start the car — security stays intact, no dealer ECM replacement.
