From the armory to the keyway.
Lock Saver isn’t a rebranded household spray. It’s built on TW25B® — a synthetic lubrication technology forged over decades of demanding military, aerospace, and industrial work.
MIL-COMM Products Company has spent decades solving one problem: keeping critical mechanisms moving under conditions that destroy ordinary lubricants. That work — for firearms, defense systems, aerospace components, and heavy industry — produced TW25B®, a PTFE-fortified synthetic prized for its wide temperature range, corrosion resistance, and clean, tenacious film.
After more than twenty years supplying that technology to the defense industry, MIL-COMM was asked a simple question by locksmiths: could the same science fix the eternal problem of locks that stick, freeze, and gum up? The answer became Lock Saver — TW25B® re-engineered into an aerosol built specifically for locks and hardware.
It worked. Locksmiths adopted it for the clean, lasting performance no oil or graphite could match. Then maintenance personnel at major government facilities put it to work across their campuses. Today Lock Saver is trusted anywhere a mechanism simply cannot be allowed to fail.
Defense-grade origins
The same TW25B® synthetic technology proven on firearms, aerospace, and industrial machinery — now protecting your locks.
Built for the trade
Engineered specifically for locksmiths and the realities of lock and security-hardware maintenance — not adapted from a general-purpose spray.
Made in the USA
Manufactured by MIL-COMM Products Company in East Rutherford, NJ, with documentation available for institutional and government procurement.
World’s best — and built to prove it.
Every can of Lock Saver carries the same claim the label has always made: the world’s best synthetic lubricant for locks and hardware. The lab data, the trade adoption, and the institutions that rely on it are why we can keep making it.
Stop replacing locks that just needed the right lubricant.
Put a defense-grade synthetic to work on every mechanism you maintain.
