To fix a stuck lock, clean the keyway with compressed air and apply a Teflon- or silicone-based lubricant, such as Tri-Flow. Avoid standard WD-40, oil, or regular graphite, as they attract dirt or turn into a sticky sludge over time.
What's the best lubricant for your lock? When choosing the best product to lubricate locks, dry lubricants like graphite powder and PTFE lubricants are best. As mentioned above, oil-based products can attract dust and dirt which can damage the delicate internal mechanism of your lock.
Original WD-40 is a penetrating oil, not a long-term lubricant. While it can temporarily free up a stiff lock by flushing out gunk, it eventually evaporates and leaves a sticky residue that attracts dust, making the problem worse. For lasting results, use a specialized lock lubricant instead.
If your key is suddenly hard to insert into a lock, the mechanism is likely clogged with debris, the internal pins are sticking, or the metal is misaligned. You can usually fix this quickly by lubricating the lock or checking for obstructions.

"WD-40 can degrade rubber, such as the rubber seals used around windows and doors. The degradation of these seals can result in air infiltration and thus lower energy efficiency." Using lubricating spray on hinges can increase the risk of attracting dust and dirt, causing them to further stiffen up over time.
The ideal way to fix a seized lock is to use a lubricant. WD-40 offers several solutions to maintain your locks: WD-40 Multifunctional Product, WD-40 Specialist Locks Lubricant or WD-40 Specialist PTFE Dry Lubricant.

Some of the top door lock lubricant options are:
Yes, the original WD-40 formula is generally bad for locks. While it can temporarily free a stuck lock by dissolving grime, it is primarily a solvent and water-displacer, not a long-term lubricant. As it dries, it leaves behind a sticky residue that attracts dirt, dust, and pocket lint, eventually gumming up the internal mechanisms and making the lock stick worse.
Yes, you can use Vaseline instead of WD-40 if you need a quick substitute. However, keep in mind Vaseline may not work for all applications, including inside locks. While it can work great on door hinges, it may be too sticky for locks and end up attracting dust and dirt particles—which can cause damage to your lock.
All-Weather Performance: Unlike oil-based lubricants, graphite powder performs consistently in extreme temperatures, making it ideal for outdoor locks. Easy to Apply: Simply puff a small amount of graphite powder into the keyhole or onto the key and work it into the lock mechanism.
Open a stuck lock by lubricating the mechanism with graphite or silicone spray, jiggling the key gently, or using a stiff plastic card to retract the spring latch. If it is a door, lift the handle while pushing or remove the hinge pins to bypass the lock.
Lock replacement costs an average of $150, with most homeowners spending between $60 and $350 per lock. Prices vary based on lock type, security features, and labor. Standard doorknob replacements are less expensive, while smart or high-security locks cost more.
