I sold my 05 Z awhile ago and forgot I had a master key stowed away in a drawer, the one with the little metal tag. I hate to just throw this away. If it is applicable to your car PM me and I will mail it to you.

Tag reads-18035

 

New to this site but would love for you to mail this to me! If this isn't, can you pm me please? I'll give you my address then

 

That is not a master key, and it won't work on any car except the one you sold. The tag is merely the code to replace it at the dealers.
