Pressing either the lock or unlock button on the remote will lock the car in 30 seconds if a door isn't opened. In my pocket with loose change, etc. this is a likely scenario.

Car Analogy

We know what you meant, but just in case someone reading this doesn't, both remote lock and unlock buttons are capable of locking the doors, especially in an accidental remote button press scenario.

Pressing lock button on remote locks the doors immediately (of course), but even unlocking will cause the doors to lock after 30 seconds if you don't open a door (even if the doors were all already unlocked to begin with).

Back to the OP's symptoms: since the door locks when you disturb it, I think you have a problem either with the knob switch in the driver's door lock actuator, or with the door lock control unit.

The knob switch has two contacts, one for "locked" and the other for "unlocked", that go to the control unit. When you turn your key in the door cylinder to the lock position, a physical linkage locks the door and sets the knob switch to locked, grounding the lock contact. I've checked in my car that when this happens, the control unit energizes the actuator to assist with locking the door. So what I think you have going on is that the knob switch is sitting right on the edge of the locked position, and when you jiggle the door, it makes contact. You could use a voltmeter to probe the appropriate pin in the control unit connector.to see if the lock position wire approaches 0 volts to ground when you jiggle the door; if so, the switch is faulty.

Otherwise, it sounds like your control unit is faulty. Hope this helps.
