2002 Accord locks itself

I have a 2002 Accord SEV model that occasionally locks itself, even when
nobody is around. Idiot service mgr says the security system is SUPPOSED
to do that. Not true. It only happens once in a while and not always under
the same conditions. I suspect a faulty sensor somewhere. Anybody got any
ideas that I can pass on the Honda service people? Thanx

 

Try this experiment:
1. lock the car with your remote.
2. unlock the car with your remote but don't open the car door.
3. Watch the lock while standing outside the car--it will probably go down
automatically.

If so, this is the way it was designed to work. I was told that Honda
designed it this way in case the owner accendently pressed the unlock on
the remote while placing the keys in a pocket or purse. I don't like this
feature.

 

My Mercedes is the same way....sometimes it locks itself sitting in
the garage. Never can figure out why.

 

In my 2004 Accord, if I unlock the doors with the remote, and then don't
open a door within 30 seconds, they will relock and the security system will
go back on. If I use the remote to roll down all the windows and don't open
a door and it relocks itself, and I then reach through a window to unlock
the door from the inside, the alarm will go off. This is clearly outlined in
the owners manual, and is a feature I like very much. If your car is
relocking under conditions other than these, such as closing the door and
NOT using the remote to lock it, perhaps something else is going on, such as
a relay problem, or a problem with the remote key itself.

 

It appaers to be working just as you described. It came as a surprise to
me.......as it is NOT described my owners manual.

Thanx to all for the prompt replies.

 

Glad to have helped. That feature also surprised me the first time that it
happened.

 

Thanks. It appears to work that way. It is NOT descibed in my owners
handbook so I was confused.

 

simple miscommunication between the engineers who designed the system,
and the technical writers who wrote the manual.

 

In my 2004 Accord EX handbook, it is on pages 84/85, under the heading
"Remote Transmitter"...

 

My '03 Accord EX will relock the doors if no door is opened within 30
seconds of unlocking them with the remote.

Now, I have rented cars which automatically lock the doors after 1-2
minutes even with the keys in the ignition (Taurus a few years ago) -
made for an exciting day at the car wash! IIRC my '88 Integra did the
same thing (ignition in OFF position).

 

Any chance you missed it?

From the Keys & LOcks section, pg. 81 in my Accord 2003 Owner's Manual:

(all models except DX)

"If you unlock the doors with the remote transmitter, but do not open
any of the doors within 30 seconds, the doors automatically relock and
the security system resets."
