Toyota Vitz prox keys

[defowach]

Hi to all. I have a lost key situation with a Toyota vitz using prox keys- push start button. Engine control box is 89661-52Q90 Fujitsu ten & smart key box is 89990-52260 Denso. I've opened the smart box & found SMD 93C86 but NO 93C46-56 or whatsoever related onto ecu box for reprogramming a new prox . Any help would be much appreciated. Thanks.

Post Smart dump.

Here is the 93C86 dump from the smart key box.

Now, open dash and find the ID code box. It is behind the heater, need to break few plastic and pull it out.

It should be 93c46, BUT can be 93c56 also.

Post the dump, and your car will start :)

Thanks gwee for your help. Will see if I can get the ID code box.

You need to get it for the car to start :)

Don't touch ECU.

With Id code and Smart dump, is enough to program key.

Hi Gwee. I've found a box listed as "Computer multiplex network body" 89221-52270 & inside there's an eeprom 93C86. Is it the dump that I need to send you back.

[gwee]

No, this is not the one. Is a small black box just behind the heater, need to "dig" it out, it will mention ID Code box.

Ok. Thanks for your reply. Do you have a picture to show where it's located exactly.

[gwee]

Same position, right at the back.
