How to Fix a Sticky Lock

Step 1: Sticky Situation
A sticky lock that just won't budge is a major annoyance around the house. But there's a sure-fire way to fix a stuck lock, and it's easier than you'd think—and it’s called graphite. It comes in a tube or a spray, and it’s better than oil-based lubricants that can gum up and stick. First, tap the end of the nozzle and squirt it in the keyhole.

Step 2: Locked Up
Stick the key in, move it back and forth, twist it and make the lock work.

Step 3: Key to Success
Pull the key out, wipe it off—and that’s it!
