How to Open a Stuck Lock on a Cabinet

Locks on cabinets often become stuck when dirt, debris, rust and other items lock them up. A chemical like WD-40 removes the blockage and loosens the lock, making it possible to turn. Locks on cabinets generally use a key. The key itself may have debris on it, which the WD-40 also helps remove. Prevent your cabinet locks from sticking by cleaning them once a month and keeping them dry. Water inside of locks creates rust, which can prevent the lock from working properly

Insert the stick nozzle into the keyhole. Hold down the button on the top of the can of WD-40 for 10 seconds. Remove the can and nozzle.

Spray the teeth of the key.

Insert the key into the lock and turn it. The WD-40 loosens the inside parts of the lock.

Wipe off the lock and the cabinet with the paper towels to remove the WD-40.
