In my frazzled state of mind while moving, I had him come out to change the main entrance and garage entrance lock and handed him the old keys. Later when things were calmer, I discovered there were other doors in the home that had a key lock and the keys had been on the keychain I handed the locksmith. I feel a professional locksmith would have said "hold on to these keys because you'll probably find out later what they will go to." Now I need to call another locksmith to have keys done for those other doors!
