Hello,
I have a 2009 RDX and I received the two black keys and the valet key. I noticed on numerous occasions with one of the keys that when I go to start it--the ignitions buzzes in a high pitched manner. When that happens I usually turn it off and it starts on the second time. Naturally I stopped using the second key where this happens but the other day it happened every time I tried to start it. I hate dealing with these issues at the dealership because it is one of those things that has to happen at the time. I am wondering if it is something simple. Has anyone else experienced this?

Thanks for your time.

 

That usually happens to me in my RDX and TSX when I don't turn the key all the way to start the car. It never happen twice in a row when I put more effort into turing the key.

Anything other than that, you might have to get it checked out at the dealership.
