BMW aftermarket/china key with NXP 26A0700 renew

[lmsvvavr]

Hi

So, I have been asked if I could program a new key on a 2007 E90 with the CAS3.
The owner, brought me a used key, which was actually a key that I have programmed to another car he used to own...

Unfortunately, I could not renew this key, and ended up renewing an original BMW key, and programmed it... luckly, it fitted nicely on the aftermarket shell...

Does anyone can shed some light on where to get the file to renew this key?
I have used the Autel IM608 to renew the original key, but there is no option to renew the key with this chip...
Does anyone has a blank file to write on this key, or shed some light on how to proceed to have it done?

Hi
I try to unlock same key before but only way to unlock this key is with CAS file that you use to programme it early

Do you have some programmer which can program pcf chips?
Something like pcf prog or Vvdi prog or rem-unlocker?

For reset can use VVDI Prog .Desoldering IC from PCB and put in ZIF adapter , set how PCF7961.After this method is posible notwork remote . Another way is reset with HT prog ,where have ,,RESET BMW KEY frm CHINA".Have wiring diagram inside not need desoldering IC.
