So how do I now get the Valet and the new Master chips register?
Tech stream would not come out of registration, and seems no immobilizers transponder chips are registered.
Edited 9/20/19 Just needed to use the master during exiting process. Sub (Valet) will not work to exit!
Here's the story:
With only a working Valet key to work with. I used it to enter tech stream registration utility.
After entering Tech Stream and going through the processes of obtaining a seed number (96 chars) to get a 6 digit Pass-code from this web interface: LEXUS, SCION, TOYOTA PASSCODE CALCULATOR / GENERATOR: Calculate Pass-code by Seed number | Immobilizer Pincode Calculator (official website)
Then inputting the pass-code into tech stream immobilizer registration utility within 10 minutes. It starter the 16 minute timer as it proceeded with registering process. I used the only working key I had: The Valet key in IC switch ON, drive door open and unlock all others closed.
In the end it gave option to register chip, by inserting key, turn IG on. I could not add the master shell key w/FOB (which includes transponder chip), at this time as I'd hoped. I had it, but not yet had it cut. Plan "was" to just insert the tip of the key and register it without inserting all the way on turning IG on. But tech stream require inserting and turning IG on.
So I elected to end registration with Valet still in IG. Hope was Valet was now register as master. If so, then once I got the master shell key cut (w/Door FOB), I could come back, and avoid the retrieval process to get a pass-code, and just register a new immobilizer chip (the master shell w/FOB).
To end registration:
Tech Stream utility stated to turn IG ON then OFF 5 time within 10 seconds to end registration. I did but security light kept blinking with key in IG. I removed key and security light stay lite solid. Tech stream did not indicate registration had ended as "next" did not highlight.
I tried procedure with driver door open and with door closed.
I tried shutting down tech stream.
I tired disconnecting battery, then reconnecting.
Still security light kept blink with key in IG and stay lite solid with key out.
If I place tip of uncut master in IG, security lite started blink as door open chime sounded.
I tried starting engine with Valet key, and that worked.
Looking in "Data stream" of immobilizer in tech stream, it does not show any key register now. How can that be?
I tried starting again. But now battery was to low at 11.4V (tech stream noted a minimum of 8V needed). So I disconnected battery again and place a charger on it.
Meantime, while battery charging. I headed out to get new master key cut:
I end up at a top notch locksmith, not some one man in a van! One, with a dozen or so employee and a $10K laser key identifying and cutting machine. This machine does not clone a key by tracing it. It reads the key and then with manufacturer information it downloads and stores, cuts a new key. That way if you bring in a worn out key, it will cut new as if using VIN at the Dealership or using and unused prefect key as a clone.
Well this did not go well. I heard the second tech that got involved say something about it was loose (speaking about a bit in the machine "I think"). Other tech said: "I wonder how that happen". They told me it (key) should work, but let them know if I've any issue. Well it did work but not well. Ill post picture below, and you tell me what you think of new cut?
Anyway I got home and pulled charge off and hooked battery cables back up. Security light still solid. Try the newly cut key and with difficult got in the IG switch and security light still blinks. With new master key in IG switch and started the 07 LX470. But Immobilizer still blink with key in.
Seems immobilizer is immobilized. That is with no key registered or so it seems. Any cut key will start it the engine.
So how do I now get the Valet and the new Master chips register?
At this point I'm not even sure if the new door FOB has a proper LX470 transponder chip in-bedded. As it is a refurbish FOB (used) I just bough from Locksmith KeyLess out of FL. FOB does work to open doors.
Here's the FOB. All numbers on the FOB match my 06LXC FOB, except the number at the bottom "06H2d"
Here's the Valet and the newly cut master. What do you think, does that look like the same cut?
