when all key lost situation we can start vehicle After immobilizer reset. but smart key can not program.
Immobilizer system can reset via OBD via x100 , skp900 like that any key programmer. but you can not program smart system.

write this reset file to smart ecu and you can program smart system. used key or brand new key

hi brayn,

im new here. Have recently gotten into key programming business but i mainly use OBD tools. Still a newbie but hae many tools such as tango, mk3, skp and obdstar x300. We have many japanese imports and prius nhw20 is many of the cars we have. Can this file help program sks fob for japanese nhw20 model incase of lost key situation? Im learning to do eeprom programmin now. Immobilizer reset ok and can start car but cannot use smart key function or lock/unlock. And if this dump can work on smart key exu, how to program new/used key? Can be done with ‘chicken dance’ methid or anything particular in techstream? Do not see any function to program prox for nhw20 in skp or is there?

thanks in advance!
