Good morning, for multiple reasons I changed out the battery on my car and now it will turn over but it won’t start. I’ve also noticed that the remote key fob will not turn on the car remotely. I’m assuming that I need some sort of activation code, etc. has anybody else ever dealt with this issue?

 

I'm not saying this is your issue, but the key fob does need a new battery here and there. Also, the push button start needs to be replaced when it has issues along with the key fob not opening the door when it's near it. Honda knows about that issue and will replace the push button start at their cost. They did that with mine when I was having issues. I suggest asking the dealer what's going on and hopefully someone else who has better advice on this forum will chime in too.
