The doors on my Honda lock and unlock repeatedly when I’m driving as well as when I park and lock the doors. I will park in the driveway which is maybe 15 feet from my front door and I can hear the doors locking and unlocking and the light on the FOB turn red off and on. When I lock the doors with the FOB I no longer hear the horn sound as I did before. I’ve read that it might be the door actuator, but I’ve also read that for some that didn’t work. Any idea what I should check first?
