Is there a toyota/lexus ecu immobilizer reset (add keys) shop in Denver I should use instead?
Most Denver 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. Regional west — about 2 days each way.
Does Colorado vehicle inspection or emissions testing affect this service?
Colorado requires emissions testing in the Denver-Boulder Front Range metro region; rural counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Colorado and federal requirements.
Which years and models does this cover?
Roughly 1997–2010 turn-key (metal-blade key) Toyota and Lexus with 4C or 4D transponder systems — Camry, Corolla, Tacoma, Tundra, 4Runner, Land Cruiser, Sienna, and the Lexus ES, GS, IS, LS, RX, GX, LX of the same era. Later G-chip (80-bit) systems are verified case-by-case. A technician confirms your exact system by VIN and module label before you ship.
I only have the valet (sub) key — why can't a locksmith just add keys?
On these systems only a master key can authorize new-key registration through the ignition. A valet/sub key starts the car but has no authority to add keys, so OBD programming hits a wall. The bench reset clears the master-key registers so your new keys register as masters — it's the standard fix for the valet-key-only trap.
