We had a busy day planned the other day. We were all bringing the girl to kindy and the wife was bringing our son grocery shopping after that. As I was loading up the kids into the car, I noticed that the keyless entry button wasn't working. I thought that was weird at first then I opened the door and put the key in the ignition. Hey, I thought, what happened to the engine lights on the dashboard? Then I glanced at the interior lights and noticed that that the switch was on the "ON" position. Well, that cinches it, battery's dead because the kids were playing with the lights!
We had to change our plans quite a bit that day. And we've learned our lesson. Next time, always check that the lights are off before we lock the car!
