Keyless Ignition does not start the car

[Maxima2010]

I got a 2010 Maxima with keyless ignition system. Today the key did not open the doors. It opens the trunk if I get realy close and press for a long time. It did not start the engine no matter what. I changed the battery of the little remote and no luck. I only hear a very weak noise and flashing car image with a key inside of it on the console. The car is in a small spot and I can not put it on a flatbed truck to take it to the dealer and can not shift to natural to push it either. Any suggestion?
Thanks

Welcome to NICO.

There must be a small tab near the gear shifter and then use a small screw driver to override the shift lock. Do you have another remote? Have you tried using it?
