After getting the oil changed and tires rotated at my local Honda dealer I'm having a problem that seems unrelated to what they did. When I got in my vehicle I noticed a yellow dash board light on. Not a green light, a yellow one. It's a key icon and a message says "Smart Entry System". I can't find anything in the book about this light, just the green one for a low battery. I changed the battery in the fob and it didn't make the warning go away. I have no idea what it's warning me about. What's about to happen here? I finally got the icon to go away by shutting the car off and locking the doors with the fob and then unlocking them. Then when I started it the icon was gone. Today it's back again. Anyone know what it's trying to tell me? It's starting OK, and the locks work.
