Lubricating a lock is best done by spraying a bit of WD40 onto the area, working the lubricant in by turning the lock a few times and wiping down the excess. Keep locks lubricated and working smoothly with advice from a licensed remodeling contractor in this free video on home maintenance.

Hi, I'm Tim Gipson. I'm going to talk to you about how to lubricate a lock. Really, the best way I've found to lubricate a lock is to use something like WD40. It's a penetrating type of a lubricant, and it's very easy to use. And, without even having to take the lock apart, all we need to do is just get close here, and just spray a stream into the lock. And then also, if you have your cylinder, we can spray. And I'll demonstrate on this, just spray some on that. And you can get good, free motion on that. Now, on your deadbolt, what you're going to do is extend the deadbolt. Spray a little bit on there. And then just work it back and forth a few times, and that's all you need to do. So, spray a little bit into the cylinder, spray it on to the deadbolt, and spray. And then what we've done is you get all the moving parts. That'll penetrate and work into your doorknob into all the moving parts. WD40 also works as a water displacement, so it keeps water from getting in there and any rust being able to form, particularly in moist areas. So I'm Tim Gipson, and that's how to lubricate a lock.
