Is there a toyota/lexus ecu immobilizer reset (add keys) shop in Nashville I should use instead?
Most Nashville 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-region northeast — about 2 days each way.
Does Tennessee vehicle inspection or emissions testing affect this service?
Tennessee discontinued its county emissions testing programs and has no statewide periodic safety inspection. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Tennessee and federal requirements.
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.
Do you supply and cut the new key?
Yes — a new transponder key with the correct chip (4C for most ~1997–2003, 4D-67/68 for most ~2003–2010) is included with the service, cut and programmed so it's ready to start the car the moment the module goes back in. To cut the blade we need one of two things in the box: your driver- or passenger-side door lock (we decode the key code from it) or a current key blade we can copy — a blade cannot be cut from the VIN alone.
