Nissan 350z Door Handle Wont Open

Put the key in and out 10 times then try to open the door agaiin didin t work.
Nissan 350z door handle wont open. 2006 nissan 350z i have electric locks when i unlock my doors i still can t open passenger door with outside latch but i can from the inside with door handle i have checked fro blown fuses but have found none. On two occasions my 2005 nissan 350z car doors were opened by clockwise rotation brushes in a car wash. The first occasion the brushes grabbed the passengers door handle and the door flew open hitting the car wash machine doing 800. Damage to the vehicle.
2005 350z door will not open from outside i pressed the remote to open front driver side door. Also spraying the interior of the vehicle with soapy water. So i was told to program the key in the ignition. What s wrong if it is just a minor repair that i could do it myself instead of taking to the mechanic.
This handle slides forward towards the front of vehicle for removal then turn to remove rod from handle.
