Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Used Denso ECU installed — paired to donor vehicle, won't start in recipient
- All keys lost + dealer not available or quoted excessive cost
- Failed Techstream pairing attempt broke IMMO chain
- Anti-theft warning persists after immobilizer module work
- Vehicle starts then dies after 1-2 seconds (classic IMMO-active behavior)
Won't fix:
- No-crank conditions (test starter + battery)
- Mechanical engine faults
- 2019+ Toyota/Lexus with newer immobilizer (text us first to confirm)
Before you order
You diagnose, we service the module.
We don't have your car and we don't diagnose it. Order once you or your mechanic have confirmed this module is the cause. If the work is completed and the car still has the same symptom because of another fault, the work is still done — a bench re-test under warranty is free.
A clone copies what is in your module.
We transfer the data as we read it. If another shop or tool already worked on the module — an unfinished clone, a tune, a delete — that data can come across too. Tell us before you ship.
What "plug-and-play" means.
No dealer programming should be needed when your original data is intact, the donor matches your module (same type, hardware and software family) and the rest of the car works. It isn't a promise that the car will start or run.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
We buy and email you a prepaid inbound label, so shipping it to us costs you nothing. Return shipping is selected and paid at checkout — Standard $29.95 (3–5 days), UPS 2-Day $54.95, or UPS overnight $94.95.
What to include in your box
- The Denso ECU (location varies — passenger kick panel, under glove box, or under hood)
- Printed order confirmation
- VIN + a note about whether you have any working key
- Your name, return address, and phone number
