hi i have 2013 rdx with tech pkg with 30k miles and last night when i tried to start the car no lights on dash came on at all
but when i unlock and lock the car using the outside door handle and button, it starts up
what do u guys think this is?

 

Key fob battery?

 

if you can place the FOB directly to the right of the start button and the car starts, replace battery with a lithium one of the same size.
