Just purchased an 08 EX35 with only one key. Dealer cost is close to $300.

Is there a way around this for lower costs besides a time machine and not buying this vehicle?

EBay keys usually work fine if a) they're new, not used or refurb, and b) you match the Nissan/Infiniti part number. Do not under any circumstances go by appearance or make-model-year. If the vendor can't tell you the matching p/n, find another vendor. You can get the correct p/n for the fob by visiting InfinitiPartsDeal.com and plugging in the vehicle VIN.

Thanks for the website! Seems I would purchase the fob there and still need to take to the dealer to program?
