The only problem is that although both keys were reprogrammed none of them work, after speaking to the guy who reprogrammed the keys to the BCU he said that it can take up a week for them to be recognised.
that's the greatest oddity
i've ever heard, but i might be wrong though... the strange thing is that it lost the immobiliser code too... on a simple repair intervention the stored data in EEPROM must not suffer, and if they replaced the main chip everything is lost... are you sure it's the same BCU not other? ...anyway, as you have hawkeye set in BCU - Programming to "always disarm with key", check other settings to be OK, at the end of all when it asks if you want to reprogramm market settings(or something like that) prompt "yes" then you can lock/unlock with the key without getting immobilised... after that open one key, read the code from the circuit board, use that code generator link i gave you and try to programm your key with hawkeye(in transmitters menu)... i heard people who did it and others who couldnt, i didnt try myself as i have hawkeye too
if no joy with the key programming find somebody with nanocom to do it
in the BCU programming menu , when you have the desired option on the screen just go further to the next one with arrow cos with the yes/no buttons you swap the options.... you'll figure it out yourself
before that try to push consecutively 5 times the unlock on the fob, maybe you are lucky , but quite unlikely to work
isn't your odometer mileage reading flashing too?...cos if it is it means that all the memory was erased
BUT to have the benefit of a doubt... wait one week before you mix things up yourself as long as you can drive it and lock it, maybe i'm wrong
