Can’t get your door unlocked? Don’t panic, we’ll show you how to fix a door lock that is jammed.
Step 1: Lube the lock cylinder
You use your dead bolt every day without giving a thought to maintenance. But one of these days, it’s going to fight back and refuse to open. Don’t panic; it’s just crying for a few shots of lube. You can get it working again with dry Teflon lube spray. It’s a better choice than graphite because it sprays on wet to soak into the lock mechanism. The solvent evaporates, leaving behind a dry, slippery powder. Start by lubing the lock cylinder (Photo 1). Click here for our favorite lube spray from Amazon.

If lubing the lock cylinder doesn’t free it, you’ll need to lube the bolt mechanism (Photo 2).
