Maybe dump can be converted to be use by obdstar?
Have no other tool for program key.

Good news,
Customer found the key!
Bad news are that the hey are not recognised by car
Also from key tool
Have dismantled and found that from pcb at least 1 piece are missing.
Now customer say that the key he found has never worked since the car owned.
As i see key are not oem.
Maybe someone know what are the parts missing.
Think that near battery should be an schotky diode?
Please take a look.
Thks

Key cs: 251DA0F6F7B6C0CDEF6DD4684999A8D0
Key stored: 03
Key active: 01
You can use CS to make a dealer key and learn manually.

with obdstar x300 dp not found any possibilities to programm the key manually.
Tool want eeprom readout for.
By itself on obd not reading any data (no connection).
Bench programmer readout nec and eeprom don't like it.
For now best option for me were to repair the key
But don't know the code of missing part.
thks
