Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Confirmed dead or non-communicating engine computer
- ✓Internal ECM failure after a diagnosis rules out sensors/wiring
- ✓A used ECM that cranks the engine but never starts (immobilizer)
- ✓Water or corrosion damage to the original ECM
Won't fix:
- ✗No-starts caused by sensors, fuel, or wiring — diagnose first
- ✗Hybrid inverter/battery ECUs — different service, ask first
- ✗Smart-key/immobilizer box faults — see the Toyota key services
- ✗Vehicles we cannot confirm the correct part for — send the VIN
The immobilizer is why the eBay ECM never starts
Toyota marries the ECM to the immobilizer, so a used engine computer from another car cranks strong and never fires — exactly the trap owners fall into. Supplying the part ourselves means we source the correct unit for your VIN and prepare it so your car will accept it, then ship it ready to install. Where the platform still needs a brief on-car registration, we tell you before you order rather than after.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Nothing to ship in — enter your VIN at checkout and we source and prepare the ECM for it. It arrives ready to install. Some Toyota/Lexus platforms need a short immobilizer registration on the car afterward (dealer or capable locksmith); we tell you up front whether yours does. Outbound shipping is selected at checkout.
What to include in your box
- Nothing inbound — supply-a-part service

- Your shipping address and phone number
