Toyota Land Cruiser 2003 Key programming

[elecautocr]

Hello members:

I am working in Toyota Land Cruiser 2003 engine 1HD-FTE, All keys are lost, I am trying to program 1 new key. I am using 4C transponder number 7E 7F 4C A8 08 00 00 00 00 ED B4 7E, but I not sure if this car uses 4C transponder. I don?t see the immo box in the car, so I am working with the ECU eeprom 93C56. ECU part number is 89666-60440.

I select master key 1 position and program the transponder, but car don?t start and DTC B2799 engine immo malfunction is still present. I am attaching original eeprom file and file with new key.

Do you have any ideas to solve this ??

Regards

Hi Bram, I can`t find immo box in car....I will look again for it. Is it possible that this car don`t use immo box ??

Check for immo box, either on the side, under the vent duct behind of instrument cluster, or behind radio
