You can put regular WD-40 in a key hole as a short-term fix or cleaner, but it is generally not recommended as a long-term lubricant. WD-40 is primarily a water displacer and solvent, not a dedicated lubricant for fine mechanisms like locks.
Lubricating a keyhole
You should not use WD-40 on electronics, bike/drive chains, rubber/plastic parts, locks, car paint/belts, and anything in contact with food or that requires a true long-term lubricant like gears, as it's primarily a solvent and water displacer, not a heavy-duty lubricant, and can damage these materials or attract dirt, leading to future problems. It's a great degreaser and rust preventative for metal, but often the wrong choice for sensitive components or heavy lubrication needs.
If you can turn the key but the lock isn't turning it is probably because there is an issue with the lock's mechanism system. In cases like these, the lock may need to be removed or replaced. There could also be a misalignment issue or trouble with your lock cylinder.
It is best not to use any oil-based lubricants like WD-40 on door locks. These lubricants attract dust and dirt quickly and lead to residue build-up. So, you should go for a dry lubricant for door lock like graphite powder.
WD-40 can damage plastic, rubber, wood, and painted surfaces. Avoid using WD-40 anywhere that may be at risk of fire, like gas appliances or electrical components.
A: No. WD-40 is used to loosen things and remove rusted parts. Anti seize is used to prevent parts from rusting together.
Most people don't know that WD-40 can solve many of their household cleaning needs quickly and easily. When cleaning a toilet bowl, WD-40 works by softening the rust and lime deposits, so they can be easily wiped away. You don't need to use much of it.
WD40 is not recommended for use with locks. WD40 actually removes the natural lubricant in the lock, often making issues worse. Keytek recommends using a specific lock lubricant or graphite powder Our top recommendation is 3-IN-ONE Lock Dry Lube.
Teflon Dry Lubricant
Teflon-based dry lubricant is preferred by some locksmiths over other options. It's a great option because, as well as lubricating your lock, it repels water and dust. Meaning that once you fix a lock with this type of lubricant, you can expect the lock to be in good shape for a long time.
Standard WD-40 oil leaves a sticky residue that traps dust and dirt. This buildup clogs the lock over time. Use PTFE or silicone-based lubricants instead.
Fixing a few stubborn locks might involve disassembling, cleaning, and then reassembling the lock. First, clean the keyhole with a penetrating lubricant like WD-40. (Don't apply household oil to the key or cylinder because it attracts dirt and eventually would gum up the lock.)
Myth: WD-40 Multi-Use Product is not really a lubricant. Fact: While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product's formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal.
A good substitute for an anti seize compound depends on the specific application. However, some common substitutes include: Grease:Grease is a general-purpose lubricant that can prevent galling and seizing in many applications.
Simply spray WD-40 Specialist® Penetrant on the seized bolt or nut and let it work its magic for a couple of minutes. This period allows the product to penetrate the small crevices and break down any rust that is hindering movement. Now all you need is a wrench and the stuck bolt or nut will be free in no time.

To fix a stuck key, apply a lubricant such as graphite powder or a silicone-based spray to the keyhole. Gently wiggle the key while pulling it out. If this doesn't work, use a pair of needle-nose pliers to grip the key and carefully work it out. Avoid excessive force to prevent breaking the key.
