V70 unlocks itself V70-XC70 1998

posted by  someone claiming to be Csaba on  Sun Sep 4 13:41 CST 2011 [RELATED]

Hi,

I have a '98 V70, and about a half dozen times I noticed the next day that the driver's door is not locked. I always lock the car!
This morning I opened the door when I found it unlocked, and the alarm went off.
I think that means that I must have locked it with the key (I do not have the remote to this car).
Any ideas how to fix this?

I got a power lock/latch assembly from the salvage yard, but I do not know if that will fix it.
Thanks,

Csaba

    Before you start to rip into the lock solenoid and such, play around with this and get a fix on its exact behavior. There are several little computers in that model and possibly three large ones. Odd software things can happen. Dealerships reset software all the time just to get the car to accept new keys. The car brain thinks that the car is completely locked and that that a break-in is occurring

    When you turn the key once to lock, it drops down the locks except the drivers? Then a second turn locks the drivers side? Or is it the reverse? I can't remember. To lock the car in the evening, open the back door and reach in and manually lock the driver's side door with the door shut. Then close the back door and lock with the key making sure the hatch is locking too. See if this changes anything. If not ......software
