Toyota & Lexus Smart-Key All-Keys-Lost / Key Generation — Mail-In Certification ECU Service
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.
Push-to-start Toyota & Lexus smart-key systems, roughly 2010–2017 (verified by VIN + module label). 2018+ FBS4 / online-seed systems confirmed case-by-case — some are not supported.

Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓You lost all smart keys and the car will not start (all keys lost)
- ✓Push-button start does not crank because no key is recognized
- ✓You bought a push-to-start Toyota/Lexus with no working key
- ✓The smart-key / certification ECU needs a working key generated
- ✓You need to add a working key on a supported smart-key system
- ✓Salvage or restoration project with the keys missing
Won't fix:
- ✗Does not repair a mechanical ignition, steering lock, or column fault
- ✗Does not fix a dead 12V battery or a no-start caused by charging/starter issues
- ✗Does not solve 2018+ FBS4 / online-seed systems without verification
- ✗Does not read a certification ECU that is internally dead (needs the donor clone service)
- ✗Does not cut or supply mechanical emergency blades
- ✗Does not guarantee registering extra keys to a live car without the vehicle present
- ✗Does not repair body-control, ECU, or wiring faults unrelated to the smart-key ECU
- ✗Does not bypass proof of ownership
All-keys-lost — proof of ownership required
Smart-key generation and all-keys-lost work is offered only for legitimate use: restoring your own vehicle, a purchased car, a repair, or a salvage/restoration project where legally permitted. Proof of ownership is required before we perform any key or immobilizer work, and a technician verifies fitment by VIN and module label before you ship. The customer is responsible for compliance with local, state, and federal law. Software key generation does not repair mechanical ignition, steering-lock, or column damage — those must be fixed separately.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Verify first: text or email us your VIN and the smart-key / certification ECU part number (and proof of ownership) and a technician confirms your system is supported before you ship anything. Once verified, remove the Smart-Key / Certification ECU and ship it to PO Box 120241, Arlington TX 76012 if you ship USPS — or 1168 W Pioneer Parkway, Arlington TX 76013 if you ship UPS or FedEx (UPS and FedEx cannot deliver to a PO Box). We read it on the bench, generate the working key or reset the smart code, bench-test it, and ship it back via the return option you pick at checkout (Standard $14.95, UPS 2-Day $29.95, or UPS overnight $74.95).
What to include in your box
- The Smart-Key / Certification ECU (immobilizer ID box) removed from the vehicle
- Year, make, model, and trim (e.g. 2014 Toyota RAV4 push-to-start)
- VIN of the vehicle
- Proof of ownership (title, registration, or bill of sale)
- A new OEM smart-key blank if you want an added working key programmed
- Whether this is all-keys-lost or add-a-key
- A clear photo of the ECU part-number label
- Your name, return address, and phone number
