The world’s best lubricant for locks & hardware.

Lock Saver isn’t another wet spray that gums up and drags in dirt. It’s a PTFE-fortified synthetic grease that penetrates the mechanism, then dries to a clean, protective film — the defense-grade performance locksmiths and facility teams rely on to keep every lock turning.

The Lock Saver difference

It’s a grease. That’s the whole point.

Most aerosol “lock lubes” are thin oils or solvents. They wash in wet, attract grit, then dry out — leaving the mechanism worse than before. Lock Saver is different by design.

It goes on with the reach of an aerosol, penetrates deep into the pins and wafers, and then sets into a light, dry-to-the-touch film. That film keeps lubricating cycle after cycle without collecting the dust and lint that jams a lock — and it shields the metal from rust, water, and galvanic corrosion the entire time.

  • Lubricates like an oil, finishes clean like a dry lubricant
  • Won’t bleed, drip, or harden inside the cylinder
  • Frees frozen, sticky, and stuck mechanisms fast
  • Virtually odorless — safe for occupied buildings
How the technology works
Built to outperform

Six reasons professionals switch to Lock Saver

Dry-Film Protection

Unlike wet aerosol lubricants, Lock Saver is a grease that dries to a light, clean film. It lubricates deep inside the mechanism without leaving a tacky residue that pulls in dust, dirt, and lint.

Extreme Cold Performance

Rated for reliable operation from −65°F to +450°F. Padlocks, gate hardware, and exterior cylinders keep turning through the harshest winters instead of freezing solid.

Corrosion & Rust Defense

Repels water, salt, and grime while shielding dissimilar metals from galvanic corrosion — the slow killer of exterior locks, hinges, and padlock shackles.

Long-Lasting Wear Barrier

The PTFE-fortified TW25B® film bonds to metal and stays put through thousands of cycles, cutting friction and dramatically extending the service life of every mechanism.

Won’t Gum Up or Bleed

Engineered not to migrate, drip, or harden. No black graphite mess, no sticky oil that jams pins — just smooth, reliable action that lasts.

Odorless & Facility-Safe

Virtually odorless and formulated so it does not foster bacterial or viral growth — ideal for hospitals, schools, food service, and correctional environments.

Why not WD-40, oil, or graphite?

Household sprays and powdered graphite each fail locks in their own way. Here’s how Lock Saver stacks up on what actually matters.
