As mentioned before, it's only cheaper short term ...
If you only need it as an emergerncy key, a $15 blank and cut from a good locksmith will suffice, but keep in mind the lesser key will wear and those "metal pieces" end up in the tumblers amking the key hard to turn.
A quality OEM duplicate can be obtained from Joe by VIN for a little more than $100 (last time I checked).
I over used the "emergency" key on my old Q (would start the car, lock with key to allow it to warm up unattended, and unlock with keye again. It only took 2 winters for the operation of the lock to detriorate. I'm sure of this, as the same "emergency" key (& original) would function easily in the other door and trunk. In short the issue isn't the key wearing out, it's where its weared out pieces end up.
This isn't an opinion, this is what has happened on both of my Q's.
