Proper lock lubrication prevents jamming, wear, and expensive replacements

Each lock type has unique lubrication needs

Always assess your lock mechanism first to choose the right approach

Most household locks are pin tumbler locks, which are found in standard door knobs and deadbolts

Graphite powder is the ideal choice for pin tumbler locks

Graphite stays non-sticky and avoids trapping dirt inside the mechanism

Never use WD-40, motor oil, or kitchen oils on locks

Always remove accumulated gunk from the keyway before applying new lubricant

Use a fine-tipped applicator to apply graphite precisely to the lock’s interior

Repeat key insertion and turning to ensure full coverage of the pins and springs

This helps the pins move smoothly without sticking

Graphite is also effective for outdoor padlocks

If a padlock is stuck, partial disassembly may be necessary

Lubricate both the shackle pivot and the keyhole for full functionality

Ensure the lubricant penetrates beneath any protective seals

High-end mortise and premium security locks demand precision lubrication

These should be lubricated with caution

Use only a small amount of a high quality synthetic lock lubricant designed specifically for these systems

When in doubt, seek guidance from the lock’s manual or a certified expert

Excess lube can clog springs, bind tumblers, or contaminate the keyway

Do not apply grease, oil, or graphite to electronic locks under any circumstances

These locks rely on delicate sensors and motors

Oil or powder can ruin circuits and invalidate manufacturer guarantees

A tiny amount of lubricant is all you ever need

More is never better—precision matters

High-use locks or those in coastal, dusty, or humid areas need more frequent care

Lubrication won’t fix broken pins, worn springs, or bent components

Call a locksmith before causing irreparable harm

Well-cared-for locks last decades and perform flawlessly under pressure
