Hello,
Dump posted here from the 93C56 memory is that of synchro b/w immobox and engine ECU.
Key data is instead store in the white box you are mentioning to be located at the ignition switch.You will find in the box the memory device Motorola 68HC05E6 28 pins SMD.
Use a suitable programmer, upload the immo dump from it and post it here, they are able members of this forum that can help you

Good luck

Hello,
If your car is 1999 up to 2000 TOYOTA AVENSIS, then the immobox is at the ignition switch.(earlier model use the 4C transponder chip with data such as the one you have posted here and the later 2000 has 4D 60 transponder chip) find attached what you should look for.In the square red is the motorola i am talking off.

If you could not see this,

then i quite remember i also work on one Avensis with the key data in Engine ECU DENSO Make memory device exactly the 93C56.Should that be the case, it means you have to read once more the 93C56 this time around by shorting the terminal of the Quartz resonator near the CPU if you are reading in circuit or remove the eeprom and read it out circuit.

Once more good luck

hello,
If Car has immobox then the information you have given about the year is wrong and the car then should be 2003 up to date car
