No immobilizer chip in FOB

This has changed a lot in last 90 days . Look at this thing called tlk1 2 or 3 read them carefully . Because lost transponder chip you will have to go to obd365 and buy a blank coffin the transponder chip .. then have it burned by a locksmith . I don't think tech software can burn a chip . Or write a chip 9 could be wrong . But tech has no transceiver. Or way to send radio waves to the chip to burn the numbers in . Tools like londsor k518 for all keys lost scenario in the electronic end of all of it . This has nothing to do with the blade .

 

The electronic key and the physical key are two completely separate things. I believe you need to have the primary key, in order to program another access key. If you don't have the primary key; you'll need to access through a fully registered, updated, validated, certified Techstream. That lock-out is obvious; to prevent easy car thief.
The dealership is your best bet; though some locksmiths has those electronic tools - but I can't see them being able to afford the licensing and access rights; without doing a whole bunch of them every month.

Good Luck.....

 

Toyota ALK requires no licensing or any of that stuff it's a standard anyone can buy tools and access easily now . For like 59 bucks . 8 have several . Look at tlk 1 just for fun theirs a video watch it . This is one method .

 

I always thought those little immobilizer chips were managed the same way as original TPMS transmitters: you don't 'burn' anything into the chips; each one you buy just has a unique code already burned in, and you teach the car to recognize that (which Techstream can do).

 

If you look on sites like obd365.com you will see bags of the coffins . They may come as you say but they can apparently be rev burned the programmed with tools like tlk1 which can relearn fubar factory remotes if it's all they're. with the missing coffin now a 30.in connector to OBD2 is needed in our old cars that immo box is under dash pad. In newer cars you just open pass. Door pull plate off insert 30 pin to OBD2. Now the I'mmo box will be ready to get original chip id. Do he can burn or program a complete remote with that data . To work system he can test data first from the setup he using once confirmed working but or program remote ..

 

I haven't done a Prius yet; but I do know on other cars - You'll need the primary key to add another fob; otherwise the ECU won't let you program another access key. The primary key proves that you own the car; only then will it accept another fob. Absent the primary key; a registered dealership scan-tool will allow access after a few physical and electronic verification.

 

All keys lost scenario . You read immo days wirelessly from the start button antennae the info pops up on screen w hex codes n all . You verify w vvdi key tool that info received opens doors readies car etc . Then burn a fob or two. The alk scenario automatically kills off all old remotes ever in existence for said vehicle so if you find a key again it will not work .

 

I think for our cars it's the tlk one needed. Realize also the 30 pin cable does not come with tlk . I access the immo box on Prius this old wirelessly to not remove dash top.

 

I really don't want to get into an argument here; but if it was that easy - What prevents a thief from electronically re-keying your car and taking it out of your driveway????? An early car may have worked that way, but everyone I've run into requires at least one fully functioning fob to verify ownership - otherwise it's drag it to the dealership.

 

My understanding is when you don't have a working fob, it requires a licensed locksmith listed as a current member of the NASTF Vehicle "Security Professional" Registry.

On top of that, the traditional Techstream won't work in the clear all old situation, you have to buy a "Security Professional" access from Toyota TIS, minimum $80 for 2 days and download the completely new GTS+ Global Techstream+ software.



Of course, its much easier if you are simply adding a fob when you have a working fob. Which is a good reason not to rely on one working fob which might be lost or could fail.

It's not clear to me if the security is the same on a gen2 but it is likely.

I know one locksmith near me can do it but he had to get the new Toyota software.

If you have more than one dealer, price shop.

 

Yeah, the "standard" and "professional diagnostic" subscriptions are offered to all comers whose money is green, but the "security professional" subscription is the one where they check your NASTF membership.

 

Yep; it's all comes down to traceability and accountability. Whomever reprograms, adds, subtracts key fobs will leave an electronic finger print - so if stolen cars are recovered with the same electronic finger print on the immobilizer; that person is going to have a lot of explaining.

I knew this one really stupid technician that gave his credentials to other people in the office to use. When I found out; I fell over laughing. This other idiot in the shop, didn't know what his was doing, wasn't trained, doesn't read theory of operations - was using his credentials to login; on critical systems. What happens when something deviates from set parameters and there's an incident? I had to lay all that out for that stupid technician; because the other idiot will just claim ignorance and say; "I don't have access rights to that".

The lawyers will be looking at fingerprints.......
