Hillman Fasteners 703185 Powdered Graphite Key Lubricant, .3 Gram

It's been about a month since I purchased Hillman Key Lubricant. I thought I was going to have to replace a couple of locks but thanks to Hillman Key Lubricant they are working like new. It is important to shake the tube (as instructed in the directions) before using it. I almost made the mistake of using WD40 spray but found out that this spray could ruin locks as it is not formulated to work on door locks. Hillman Key Lubricant is what you need to lubricate the lock if you're having difficulty turning your door knob.

You will probably loose track of the second tube because the first will last so long. If you cyber shop, this is a 2-pak purchase. Maybe I'll give the second tube away instead of trying to keep track of it...

It is easy and does what it is meant to do!

I live in an apartment complex. The maintenance department treated my sticking lock with WD40. The lock was UNSTUCK when I used the graphite. All my neighbors are borrowing my supply

Some reviews sounded like they didn't read the simple directions, like the need to shake the tube before using! Make sure you do this, holding it flat while shaking gently! Any locksmith will tell you to use graphite now

very good product! keys work well in lock now!

This worked like a charm and got my sticky doorknob cleared put within minutes.

Worked just like it's supposed to.

It did nothing to help my sliding door. For the price, you can get a lot more of something better elsewhere.

The tube of powdered graphite was empty. I noticed residue near the cap so it was either faulty or it was just a used product thbat I received.
