To fix a sticking mailbox lock, apply a dry graphite or PTFE-based (Teflon) spray directly to the key, avoiding oil-based lubricants that attract grime. Insert the key into the lock, work it in and out several times to distribute the lubricant, then wipe away any excess.
WD40 strips a lock of its natural lubricant and can make your lock stiffer or even sticky. Likewise, it can attract dust and dirt into your locking mechanism and lock which will affect how your lock works. Top Locksmith Tip: Use a lock lubricant instead of WD40 to help with stiff or sticky door locks.
For outdoor locks, PTFE (Teflon-based) dry lubricants or specialized silicone-based sprays are the best options. They repel water, withstand temperature extremes, and leave a dry film that does not attract dirt, dust, or grime.
Polytetrafluoroethylene, or PTFE, is a Teflon-based lubricant that dries inside the lock to leave behind a non-stick, water-repellent film on all the surfaces. Since it's dry, it doesn't attract dust or dirt.
You should avoid using the original WD-40 formula on door locks. It is a penetrating solvent, not a true lubricant. While it provides a quick fix, it will eventually strip away existing factory lubricants, dry out, and attract dirt and dust, leaving your lock gummed up.
To fix a stiff lock, apply a dry lubricant like powdered graphite or Tri-Flow into the keyway, then work your key in and out to distribute it. Avoid standard oil-based products like WD-40, which can attract dirt and cause the lock to gum up.
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.
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.
To open a stuck mailbox lock, spray silicone or graphite dry lubricant into the keyway and work the key in and out. If the lock remains jammed, push inward on the mailbox door while turning the key to relieve pressure from overstuffed mail.
"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.
No, you should never use olive oil to lubricate a lock. While it may provide a temporary fix, food-based oils go rancid over time. They will dry out, become gummy, and trap dirt and dust, permanently ruining the lock's delicate pin mechanism.
To loosen a stiff lock, apply a dry lubricant like powdered graphite or a specialized PTFE spray into the keyhole and work the key in and out to distribute it. Avoid oil-based lubricants like standard WD-40, as they attract dirt and can worsen sticking over time.
Super Lube Multi-Purpose Synthetic Grease has become their lubricant of choice for high security locksets, combination locks and multipoint locks. They selected Super Lube for its superior lubricating qualities and ability to work in a variety of applications.
For outdoor locks, PTFE (Teflon-based) dry lubricants or specialized silicone-based sprays are the best options. They repel water, withstand temperature extremes, and leave a dry film that does not attract dirt, dust, or grime.
Not only can you use Vaseline before applying eye shadow, but you can also use the jelly to remove it — and eyeliner and mascara — in one of the gentlest ways available. "It's light and lubricated, so the makeup slides right off without harming the skin," dermatologist Mona Gohara told Allure.
The best lubricant for a sticky lock depends on the lock's location, but Teflon (PTFE) or silicone-based dry lubricants are generally the top choices. For maximum longevity and clean operation, professionals recommend using specialized products rather than standard wet oils.
The best overall lubricant for locks is a professional-grade dry lubricant like a PTFE spray (e.g., Houdini Lock Lube or Tri-Flow). Unlike standard oils or greases, these dry lubrics leave a frictionless coating that won't trap dirt, dust, or metal shavings, keeping your mechanisms smooth and corrosion-free.
Sometimes a little jiggle is all you need. Gently insert the key all the way into the lock and try wiggling it up and down while turning it slowly. This can help the pins inside the lock align with the key's grooves. Be careful not to use too much force—you don't want to break the key off inside the lock.
If your deadbolt or door lock jams, it can be due to dirt buildup or general dryness. Exterior doors get exposed to the elements, and tiny particles can get into the lock, making it hard to get the key in or turn it to unlock the door.
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.
