'99 Corolla Door Locks Constantly Opening

[Arkham]

Power door locks will open after they are locked, while driving and when the car is just parked. I disconnected the passenger switch-problem continued. Disconnected driver switch-problem continued. Any suggestions?

The power locks have a feature to prevent you from locking your keys in your car, where if the key is still in the ignition and you try to lock the driver's side door while all the other doors are locked, it'll unlock all the doors.

Perhaps you're either triggering this accidentally without noticing, or something is amiss triggering it under other conditions.
