That looks like a transponder key but my 01 is different. You can check at a dealer or maybe someone on the forum will know for sure. Transponder keys are expensive and normally you have to have them programmed at a dealer. If you get the key, cut and programmed, for less than $150 you're probably doing pretty good. Some locksmiths now have aftermarket keys and they typically cost less than a dealer.
Be careful and don't loose the one you have, and next time, insist that the dealer provide another key. I don't know why people keep these keys when they trade their cars and the dealers know how much they cost so they aren't very motivated to supply an extra one.
Your key looks like my 2003 Pathfinder key, I don't think mine has a transponder, so it should be fine.
Try it and let us know, i think the worst thing that can happen is the car will not start until you use the transponder key if it does have one.
Now, in case the master key has a chip in it and I try to use those new keys to start the car, will there be any problem?
Thanks.
from what i understand your car will not start if you don't have them programmed, and it will screw up the master key as well and i think you'll have to have that programmed again too.
if it has a chip you can see it, it's a big blue thing on one side of the key
