A customer have order a new key for his vehicle as he loss one of his key. However, he find that key later and he would like to use it as additional key. But we find the key track was blocked. Is there any way to re-open the blocked key track with developer mode?

yes,..the way is simple,...just read what stardiagnosis needs,....when you need to wake up the blocked track!

The new service green or orange plastic key,....,..and some time to recreate the old key track!

Do you means the green workshop key? The dealer will not accept to order the green key even we got the authorization letter from car owner.
