Driver Door requires extra effort to "pop up" and unlock
I have a 330 CI.
The problem -
Recently the driver side door lock doesn't come up or unlock with the remote any more, and when using the key, I have to give it a bit more force to open. What I mean is if you insert the key (so the top of the key is at 12 o'clock position) I turn it to the left to the 10 oclock position and I hear it unlock, but the lock doesn't pop up, if I do it again the passenger lock pops up. In order to unlock the driver door, I have to turn the key to the 9 oclock position, however, from the 10 to 9 oclock position, I feel more resistance.
A few weeks after this problem started, the tumbler broke (the locks did not responds to the key at all), I recently replaced the broken part and the tumbler is back to normal (except for what I mentioned above).
