never worked on one, i can only give suggestions, try reading eeprom as 93c66, 93c56, 93c86 to see if you get a dump that will be recognize by a programmer, I did look up the eeprom number and can't find much information on it. If you have tango+ give it a try.

Hi
I read the Brayn solution.
It work 100%.
Maybe your procedure is wrong.
You can use a used smartkey.
Please write the detailed instructions you did.

I red the S2943 eeprom in the smart box as 93c76 and 93c86 and wote the Brayn resetted bin file to it and went to the car and starting register a used smart key and used the Toyota techstream V 12.10, SKP900, x100pad 2, x100 pad plus and Gscan .. its failed to register the smart key .. and i noticed that when the Brayn solution witten to the smart box the security LED will blinking fast but when the ORI file returned to the smart box the security led is came back off.

i red the S2943 as 93c86 and attached it to Tango but not accepted because the invalid file size ..

Note .. the used smart key is all black colour not the gray one .. any one can give me hand in that ? a virgin file for the attached 93C76 will solve the problem ..

Thanks

I think i might have your solution, I imagine this is the one you have to put the fob inside a slot. if it is, read ecu 93c56 and emulate or write new 4c transponder, put new transponder inside fob, that should start vehicle, once you do that you should be able to program remote manually.

My solution
1 Put the master key inside slot.(Master key is black color.)
2 Reset the transponder ECU.(I use a T-300. If you have it, You choose TOYOTA - IMMO - TYPE2.
3 After reset,You have to put off the smart key from the slot.(security lamp on)
4 After security lamp on,Put rhe smart key insaide slot again and Push start switch on - off five times.(security lamp blinks)
5 Write the virgin file to the smart Ecu.(S2943-93C76)
6 Put the smart key the inside slot.
7 Register smart function using Tchtream.
Done
