I have a 2013 XF Sportbrake. This winter have been rather troublesome. The front door freezes. Well, not the door, but the lock. Still after hair dryer and warm garage, it still freeze. Yesterday I had to open the door from the inside. It simply wouldn't unlock. I guess I have to grease it up. But I'm not sure how to do it. I can see three screws on the side of the door. I guess I can unscrew this, but it probably won't do anything. Do I need to remove the front panel on the inside?

 

Yes, you have to remove the door panel. Use white lithium grease as it is water repellent.

 

Thank you!

 

I would think that GREASE in contra-indicated. I would first ask a local locksmith what I should use, but I expect the answer is a specialized dry graphite lubricant.
