Iveco Daily All Keys Lost / Autel im508 

First tried to write the key with Xhorse key tool plus pad, removed the immo block under the steering wheel, eeprom 93c56, tried to write XT27 prepared for Iveco but the programmer can not write into it because it gets locked, tried not prepared to write but the engine did not start, maybe there was a problem that it was necessary to hold the chip longer near the antenna that would normally activate. Then tried Autel, but everything was the same, the engine did not start, then took the chip original NXP pcf7936, the first time did not start but then everything worked!
