The security system recently seemed to change on our 2004 Honda Odyssey. It now automatically locks the doors after exiting the van. It originally did not do this and did not "chirp" when being locked. Any ideas on how to go back to the quiet version?

take it to an alarm expert. or if if your up for the job try disconnecting the plugs that go to the alarm converter box under the hood, near the battery.































I recommend taking it to a pro.
