If you have an original key, you can get a copy made at a key clone shop for less than most dealers will charge you for a new original.

In my case, one dealer wanted to charge me $50.00 for one original, and another dealer wanted $19.95 for an original, (the price of a clone key somewhere else). Needless to say I went with the more reasonable dealer. I was told it would take a week, but it only took 2 days.
