2003 Civic Door Lock

[siedleckib]

I'm having some trouble with the driver side door lock on my 2003 Civic sedan. When I lock the car using the power door lock, it is quite difficult to get the car key to unlock the driver's side door. The dealer said they could replace the lock cylinder for about $90.00. But I wonder if the problem isn't in the power door locking mechanism. Anybody had similar problems? Suggestions would be appreciated. Thanks in advance.
