Hi mates,
This is corsa pick up made in South africa (2006). Immo has 0L72A.
Customer had a problem with ignition, he bought new ignotion with 2 keys. He wanted an additional chip, so that he shall use 2 keys.

I opened and read the processor, got the PIN also, prepared another chip ID40 with zedbull, The car started only once. then the spanner blinks, and it only cranks.

There was no communication with the Immobiliser and the ECM with launch/OP com?tech 2!!!!!

the car was starting before i produced new chip, now both are not starting. I checked the soldering, and all fuses are ok.

can some one explain me what shall i do?
if the immo box was damaged for some reasons, would it affect the communication to ECM? because i could only communicate to BCM, and i get the fault saying Immobiliser signal low.

Awaiting for replies mates.
Thanks
