How to do Fiat key programming? Lonsdor or Obdstar?

Why it’s not easy to program Fiat keys?
Fiat vehicles are one of the most complicated to do.
The reason is the immobiliser chip unlike most other cars on the market today can’t just be programmed in using the information already written to the chip. The chip also has to be pre coded with information that can only be taken from the ECU itself. Now in previous years the only way to do this was to remove the immobiliser unit and de-solder the chip from the circuit board, then you could read that information and write it to the chip. Then we had to re solder the chip and install the unit back to the car before programming the key. As you can imagine this had inherent risks as the chips are so small and the circuit boards very delicate.
Which key tool can work for Fiat?
Fiat keys can be done with some universal key programmers like Obdstar key master and Lonsdor K5158...
Obdstar key master is confirmed to do pre-coding and programming
Lonsdor K518ise is confirmed to add/program new keys.
