Lock Saver, answered.
The questions locksmiths, maintenance teams, and buyers ask most about Lock Saver.
What makes Lock Saver different from WD-40 or 3-in-1 oil?
WD-40 and household oils are wet lubricants that stay tacky, so they pull dust and grit into the lock and can gum up pin springs over time. Lock Saver is a TW25B® synthetic grease that penetrates the mechanism and then dries to a clean, protective film — it lubricates like an oil but leaves the dry, non-attracting surface of a solid lubricant. The result is smoother action that lasts far longer between service.
Is Lock Saver better than graphite for locks?
Graphite is a dry lubricant, but it provides no corrosion protection, is messy to apply, and can clump or cake if it ever meets moisture or oil — sometimes jamming the very lock it was meant to help. Lock Saver delivers the clean, dry-film advantage of graphite while also protecting against rust and water, without the black mess or clumping risk.
What temperature range does Lock Saver handle?
Lock Saver performs reliably from −65°F to +450°F. That cold-weather capability is why maintenance crews rely on it for exterior padlocks, gate hardware, and door cylinders that would otherwise freeze in winter.
Can Lock Saver free a frozen, sticky, or stuck lock?
Yes. Lock Saver penetrates deep into the mechanism to quickly free frozen, sticky, or stuck lock components, then leaves behind a lasting protective film so the problem does not return.
Is it safe to use in hospitals, schools, and correctional facilities?
Yes. Lock Saver is virtually odorless and is formulated so it does not foster bacterial or viral growth, which makes it well suited to healthcare, education, food-service, and correctional environments where cleanliness and low odor matter.
What else can I use Lock Saver on besides locks?
Lock Saver is ideal for all locks and hardware, plus hinges, doors, valves, bolt threads, cables, chains, and virtually any abrasive moving part that needs quiet, long-lasting, corrosion-resistant lubrication.
What sizes does Lock Saver come in?
Lock Saver aerosol is available in a 12.65 oz shop/service size and a 6.1 oz toolbox/travel size, both with a precision spray straw. It is also available as a solid grease and as an oil in syringe applicators for pinpoint work.
