Do I need the master key to open the door or will a duplicate metal key work?

What is your question?

I don't like hiding the key outside the car. I want to hide the master key inside the locked car while I surf and carry a duplicate metal key in my wetsuit to open the door when I return. If I have the hardware store cut me a duplicate metal key, will I be able to use it to open my door?

What makes this problem better or worse?

If a duplicate key from the hardware store would could open the door.

How long has your 2014 Nissan Rogue Select had this problem?

I just bought the car last week.
