[KALNAJJAR01]

thanks for every one effort,
I have 89661-07340 - Denso, tile 2003 no immo box, IC 900 with eeprom 93c56.

I have this car after some one did not finish the job.

I have Carprog original open for airbags only, I did read this eeprom as 93c56 from the EEPROM general column. no 16 bit option just 93c56.:

is ok to use carprog to read it?????? YES or NO. see dump if it look ok .


ECU number 89661 - 7340- Denso

I did send dump file to a friend then he send me good file all are attached here.

EEPROM was not solder to the computer when I got it, was not sure if the pin 1 position right with ECU - IC900 board , please see attached picture, and tell me if ok or must flip it back.????????????????

I did go to the car and insert one Gary key (valet) this is the only key customer has, waited 10 seconds then open ignition and push brake peddle 5-6 time then started car but car di not start and security light at dash still blinking.

need help to figure out if:
1. my friend good file is bad or good or my dump is bad or corrupted?????
2. is EEPROM pin 1 position to ECU board right or wrong???????????????
3. 1 Gray key will do the job or must have 2 black master keys plu Gray total 3 are a must to make car start???????????????

KALNAJJARD we will not able to help if you keep opening new folders, both files I have checked they are over 512bytes, we only need file fropm keydata and immobox.

1st I need to know the history have you still got the original key you want to synchro?
If the answer is (NO) we need your new key data, and we need immo box dump 93c56 this file is 512bytes, I will write this dump for you to start car.

what do you mean " tiris format.."
with what I can use.
have carprog only

[KALNAJJAR01]

customer has only new Gray key ,never order any original black keys as I mentioned in the post. car came from auction like that with gray key. security light keep blinking

I used Carprog to read 93c56 from ECU, as I mentioned in the post.

do you need me to do what, or tell the customer!!!! next
do I have to open the key with blade and read the EEPROM from the gray key or must order black 2 keys and open one key then read eeprom from key
thanks

KALNA forget carprog read your new key with Zedbull or any key programmer and take the photo of this reading will be the tiris number lets start from hear.

[KALNAJJAR01]

I do not have any zedbull
I have ck 100 from china and Toyota techstream only and autel scan tool

I do not have any zedbull
I have ck 100 from china and Toyota techstream only and autel scan tool

In that case go to Toyota dealer for a new key ready cut then programme with Toyota techstream, otherwise buy clone zedbull.

you load a virgin file but your car not accept the key, no matter for the 4c key either grey or black, it must start the car, try to read the key by any reader then post here i will give you a working dump to start your car. regards

[KALNAJJAR01]

I will order 2 master black keys then use my chines clone techstream software to program it.
do I need seed and pin code for it , or just regular program.
1. do I have to erase all keys then program the new ones?
or
2. reset immo box then program ?
which one is the right weat to do it.
thanks
