My lock on my door has become really hard to twist, and I keep breaking keys. This on only on the D/S. Itll twist over except the very last part to unlock it, itll hold tight and just bend my key. Has anyone else experienced this and how did you get it fixed?

Thanks

 

Pull the lock cylinder out, clean it out and lubricate it. If you want to go the next step, take the cylinder to a locksmith and have them clean it out, they have special cleaners and lubricants.

What Dale said. Also when you remove the interior trim piece make sure there isn't anything interfering with the mechanism as it moves. The plastic clip that holds the locking rod to the lock cylinder broke rendering the car un-openable.
