I was unsucessful in a posting to another forum; maybe someone in this forum had a similar problem. My 2007 EX-L is set to lock the doors when reaching 9 mph, as set by the factory. A few weeks ago it started adding a beep right after the doors lock. I cannot figure out why (after searching the Owners Manual, asking the dealership, searching the forums, etc). If someone can tell me what is causing this irritating sound, and how to eliminate it, I would be deeply indebted! Thanks very much!
