Fix squeaky doors in 10 minutes

A squeaky door or sticky lock usually is not a mystery, it is a diagnosis. In 10 minutes, you can figure out whether the noise is from hinges, latch friction, or a sticky lock cylinder, then use the right low-mess fix.^[27][34][29]

If the squeak is from the hinges, start there first: wipe off dirt, then use a dry lubricant or a little petroleum jelly on the hinge pin, working the door open and shut to spread it.^[6][8][13]

If the door is sticky only when it closes, check the latch and strike plate. Tighten loose screws, clean grime, and adjust the strike plate if the latch is rubbing or missing the opening.^[2][3][35]

If the key or lock is the problem, clean the keyhole first and use a dry lubricant like graphite or silicone spray. Several sources warn that oil-based sprays can attract dirt and make the lock stick again.^{[29][31][33][28]}
