TOYOTA RAV4 YEAR 2013 ALL KEYS LOST

[achaccha]

Hello Friends
I have a new case with a Toyota Rav4 2013, total lost key. I went to get the immobilizer and see that this does not have eeprom. the customer bought a new key and see in dealership that has the letter "H". the sword
Podiran tell me how is the procedure for programming the key in this case?
that memory should read the immobilizer?
T code communicates with the immo, but can not reset, Avdi not be reset.
thanks for your help

MW_46_66 need to solder or 86, you can see the place of the drawing. Can record anything Switching the combustion.

bllinda what do u mean me-46 66 if u give detaile i will try to read i have to vergin immo snd one is from car

[achaccha]

I can understand that by welding a c46 or c56 eeprom or a c66 or c86. then be connected to the vehicle, open switch in on and then desoldering eeprom to get a reading, then work based on this reading eeprom.
being is also possible to obtain a reading on a virgin immobilizer and then apply to this case.
will do tests and I will be discussing.
Thanks for your feedback

did u done like this or read data ?

[rashid01]

i think sold wire in 8 wire the connect to eprom reader the slect ic no and try one by one nombe may be like this we can read

[siyadk]

No i cant understand and don't know the fuss is about .. Why do u need to read this ic..??
If u cant read the key data of new chip, how will you add key data to dump? No tools at present can read H chip..

Or else u need to have virgin file

[rashid01]

no need read chip h just read dump in immo and make virgin and add key via tool

[siyadk]

Usually adding a new key requires a registered key for any tool

But if u did it.. Thts a good news!!! If tht case we can write virgin files and add new key to the cars.
Rashid01, can you describe the whole process again from start till end.

Gentlemen keys stored in the TMS3705B

[andrius]

TMS3705B is only a comunicator device, not a place to store keys :)

[marco70]

Where do you think the keys are stored?

He knows where is the keys since he can read the immo.

as you must have seen in datasheet, it is simple modulator, demodulator, with some integrated comands, but without any actual flash, eeprom memory to be programed, TMS chips are usualy used in toyota, even Zed-bull has one :) it is simple comunicator, not a mcu, that could be reflashed to store any user code. keys may only be stored in that beautiful mcu, and as i see of pinout, ic4 is ready for 93Cxx eeproms :) so my opinion is that mcu must store keys. the most interesting thing is what that mcu is ? :D and how to read it :)

[rashid01]

i cannot read i replace immo new and programe key

[electronicdeivi]

can someone please help me with the resistance value r32 photo that is posted to disarm damage resistance from already thank you very much for your answers

you cannot reset immobilizer for H chip immo systems by any version of techstreamin regions except US. Need to replace with new immobilizer unit. Atleast this is my knowledge ...care to disagree?
