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)
