Can anyone let me know where I can find a replacement drivers side door handle with the smart button for my 2006 Murano...outside of going to the overpriced dealership? I can find tons of regular handles online but none with the smart button. Thanks in advance for any help!!

Looks like your part is 80640na:

It was replaced later on with different part number which is 80640-CB01A (again intellli key)
This handle is the same for left or right side. Also there's a handle base not sure if you need it which is also the same for left or with intelli key 80611-CB01B. Tascaparts, everythingnissan, courtesyparts, google etc are your friends to buy parts online.

how do I know if I need a smart entry door handle or a regular door handle?
