hi

so I had an issue with no firing on 1 and 4 changed coil pack and was just the same
I was advised to change the ecu which I have done and I do have the key from the car the exchange ecu came from
after swapping the ecu and with the key present the car will not even turn over
I have noticed that on turning the key the alarm light does not go out so I am suspecting there is a security issue

there is another box next to the ecu labeled contr asy - r/cont lk & alrm sys mn

my question is this

have I got the ecu / key swap wrong, it there any reset I should do ? or do I need to go back and get the other box ?

many thanks
