It has to be a problem in the left hand door.
When you turn the key in the left hand door, you're giving it some extra force, which forces the lock to turn. When you're using the right hand door, the car is trying to lock the nearside door all on its own. If the mechanism is stiff or worn, the locking mechanism isn't strong enough to engage the lock so it re-opens the door.
I think all the action is in the door latch (that white plastic component you can see around the hole in the door where the striker is.. You can take it off from inside the door without dismantling too much. Give it a goof lube' and make sure all the connectors are clean and good. You want to give it the full amps of electricity when the door locks.
That ought to do it.. but you could have good old fashioned lock wear, where the lock isn't lifting the lever that activates the mechanism enough to give it a proper connection (so you get a weak "lift"). There's not much to do about that one (new lock time) but try lubrication first...
No bullets for Chaingun..
