Hyundai Atos key

[armpower]

Hallo

I've a Hyundai Atos and i need to make a spare key.
The original key have pcf7936 inside.
The immobox is Bosch 95400-02600 i think a smartra system.
Which is the fastest way to add a kye to this system.
The immobox doesn't have any eprom inside, and looks like this:
370904
Can i use a blank pcf7936 or need a sort of precoding to use it?
Can i add a new key with diagnostic or i have to read ecu or immobox?
Tango have only Atos with eprom immobox.
Any help appreciated

Cheers

why dont you just calculate pin code from vin and add a id46 with some tool (sbb, t300 , fvdi....) ?

if you want to make it from dump i think you need to read kefico ecu eprom:
370909

Ok.Thanks for the tips.
But i have a question.Can i add an id46 transponder without precoding?
Can i use a blank pcf7936 or i need precoding?
If i need precoding which are the correct parameters to write before add transponder?
Thank you

i just use blanks TP12 marked chips from JMA , dont know what chip u have, try it blank if it dont work precode it to ID46, you can do it in EFFL zed bull or anything else u use.

Hyundai, KIA ID46 no need any precode. Go ahead with blank PCF7936.

Car done.
As told by the helpful user on this forum, no need precoding.
Blank pcf7936.
Coded with SBB without problems.Before coding used inbuilt Vin to Pin generator than coded.
Thanks to all

What is the history with your car?

If pin wrong: ECU dead or no power, break communication wire or ECU changed before.

history is.........lost keys and nothing else.....communication with ecu is ok .....
vin 369495 and code try 378832.....

is there any way from wrong transponder?
