I just bought a 2003 maxima crashed and it only came with one key. I was quoted close to $200 by the dealer to have another one cut and re-programmed. Could itthe re-programming be done on the outside or is this a dealer only deal. I could buy the blank key off ebay for $20 and do it myself if possible.

 

it's not possible to program yourself. Our keys are quite expensive and so is the programming labor
