What I've discovered over the past year is that once the driver's door is closed, the system thinks all is well. Typically, then if I walk away from the car, there will eventually be the single beep and lock. But if I open the trunk before that single beep/lock signal goes off, the system gives off the multiple beep. And even after the trunk is closed, the system won't lock automatically. If I walk away from the car, it's unlocked. So my routine - when I know I'm going to unload the trunk - is to leave the door slightly ajar so that the system doesn't think the car is being locked up. That has at least helped as a workaround to the problem. Where it is still a problem is when I go to the store. I don't always remember to leave the door ajar while I go back to the trunk to get shopping bags. Then I have to remember to press the lock button or the car won't be locked. I think it's a really poorly designed system. Do all Honda autolock systems behave this way?
