Is there a toyota/lexus ecu immobilizer reset (add keys) shop in Billings I should use instead?
Most Billings shops don't keep the bench equipment for toyota/lexus ecu immobilizer reset (add keys) — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-country northwest — about 3 days each way.
Does Montana vehicle inspection or emissions testing affect this service?
Montana has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Montana and federal requirements.
Which door lock do I send, and how do I remove it?
Either the driver- or passenger-side door lock cylinder works — most customers pull the passenger-side lock so the driver's door keeps working while the car is apart. On most of these models it comes out with the interior door panel off and one clip or screw. If you'd rather not pull a lock, a current key blade — even a non-transponder copy or a worn valet key — gives us the cuts instead.
My immobilizer might be in a separate box, not the engine ECU — how do I know?
It varies by model and year: many have the immobilizer inside the Denso engine ECM, others use a separate transponder ECU (immobilizer box) behind the dash. Text us your VIN and a photo of the module label and a technician tells you exactly which unit to pull — before you ship anything.
