Wow. Super tech answer!! Not sure about disconnecting battery as not sure of how to reset alarm and add code & radio code Anything else is beyond me. Though garage might have sussed it, bit I would have to give them longer to find the needle in the haystack £££...

Alarm no hassle just don't leave your keys in car with doors shut as in some instance alarm will arm or activate central locking then you locked out :-) keys best in hand then is sirin starts squeeling you can blip it off.

 

not sure on your radio code so check that with the radio manual.
