Key Won’t Go In? Try This Simple Hack

If your key won’t go into a door lock, don’t reach for the WD-40. All you need is a graphite pencil to solve the problem. Over time, dust and dirt make their way into the door lock cylinder, causing the pins to stick. The fix is to use a dry lubricant like graphite spray, such as 3-In-One Lock Dry Lube, or powdered graphite to lubricate the lock mechanism. If you don’t have any on hand, you can use this quick hack that uses the graphite from a pencil to get your lock working again.
