My 04 coupe seems to be locking itself. heres how it goes down...I unlock it with the fob, open a door, shut door, and come back minutes later to discover its locked up on its own. Second time I unlocked it, started her up and shut it down, closed door and came back to find its locked AGAIN I understand it will relock in 40 sec if no doors are opened and I recall in the past that when I pressed the fob to unlock it would stay unlocked

Any suggestions? Only thing Ive done recently was add led map lights

 

yes, there was a recent thread on this that I started, as my 06 was doing that too. It has something to do with the car sensing you've walked away from it and securing itself, but it hasn't done it since. Just a couple of times. This car is alot like a Nintendo game, all sorts of hidden buttons and sequences to get to the bonus points. Look up slef-locking on the threads and you'll find the recent posts, form about Sept or so.

 

It is always possible that the remote is acting up. Maybe the battery is going dead or the button is stuck. I had this happen once when the remote was in my pocket. The button was sticky or something... the slightest touch on the remote locked the doors.

Try unlocking the doors and putting the remote somewhere far away where the car won't pick up the signals. That is the easiest way to find out if you have a problem with the remote.

 

Did just that and it stayed unlocked. Jinggled the fobs close to the car and it remained unlocked. Im starting to think that because I keep my keys on a hook inside my pantry door, that the pantry door (which is in the kitchen adjacent to the garage) jostles the hanging fobs enough to make them smack the door and sends a signal.. Ive currently have the fobs sitting in the garage next to the car to see what happens. When I get home I'll have a look see

 

It could just be your fob acting up. It may not even be touching anything. Just keep the fob far away from the car. I had a friend who had the same problem. His alarm kept going off. I told him to replace the battery.... that was the problem. If that is your problem then it is an easy fix!

 

All,
This from Section 8N of the 2004 Service Manual, page 8N-35

Automatic Locking

The automatic locking function can be activated or deactivated with the DRB III

T. The interior power door lock
switch may also be used with the ignition switched on by pressing and holding the power door lock switch for more
than 5 seconds in either the lock (auto locking switched on) or unlock (auto locking switched off) position. The

interior power door lock switch can be inhibited with the DRB IIIT.

 

This particular year and color CF has been known to come with a ghost who is a particular prankster. Annoying. There is a fix. Scare the s**t out of him with a whoopee cushion.
This should fix the problem. One more thing though, the whoopee cushion should be one of the new self inflating ones that omits several loud, long and wet f**ts. Just don't forget to clean your seat afterwards. Good luck.

 

The PT has that function that locks the doors when your speed hits 14mph or whatever. For the last 2 days, mine lock at 14mph, then keep auto locking at higher speeds, about every minute or so. No check engine light. Remote entry, all other functions are normal.
