Intermittent no start

My 2007 5.7 4x4 Tundra has a intermittent problem. Back in February I took a trip and I stopped to fuel up. When I went to start the truck nothing, no dash lights nothing. Turned it off back on it started right up. Didn't do it again until April then it took about 5 times before it started. Same thing no lights on dash no crank no nothing. A couple weeks ago I couldn't get my steering wheel to unlock. It took 10 minutes. Ignition? Not a smart key is it?

 

It could be related to the key or key fob. My dad's 07 had a similar issue a few times. I just locked and unlocked it a few times with the fob and got it to start. He replaced the battery in his key fob and the problem went away for a while.

 

Thanks, I discussed this issue with my brother yesterday he also said it cod be the key.. so i will replace the battery in the fob and go get a new key.
