Houdini Lock Lube Professional Lock Lubricant Spray, 11 oz - Greaseless, Graphite-Free, Dielectric Cleaner & Protectant for Door Locks, Hinges, Latches & Electronics - Anti-Rust Formula

10/10 recommend. Stuck lock and your key won’t go in? Or your key really struggles to go in and can barely come out? Get this. It cleared our stuck locks in less than 10 seconds after treatment.

UNIQUELY - The BEST! I was informed of this ‘lubrication’ product by a very highly skilled veteran locksmith. Previously I used Triflow with PTFE and various other lube type (graphite, silicones, etc) … but being a chemist involved with analytical QC work on various rocket fuels I am always “open” to learning & trying new products & formulations! I have used ‘Houdini’ now for several years on locks, door hinges, garage door hinges & tracks, keys, car door hinges, etc., always very sparingly (it is a bit pricey), and in each use this product proved well up to each task, silencing, not staining, lasting excellent lubrication! I particularly like the absence of “drip stains” when silencing sqeeky stiff door hinges, and the absolutely minimization of any chemical odor! My next trial will be as a treatment on wood screws ;-)). Give this a try, I found it well worth the $$ and effort to buy/ship it when local big-boxes only carry the ‘blaster’ types of silicon, ptfe, etc., types! I found that I only needed a small “spritz” a minimal amount will creep into the hinge pin ir lock tumbler pins, and it lasts, so the can goes a very long way!

Key was difficult to insert in deadbolt lock. One small squirt and works like new. Probably lifetime supply at this size, lol.

I have a garage lock that has always been sticky. One day it wouldn't open at all. Someone said "WD40". I tried that. Nothing. Then I read "Graphite Powder". I tried that. Nothing. Then I read "Never use WD 40 and especially never use that with graphite powder". I thought it was time to call the locksmith. I saw this on Amazon and bought it as a last ditch effort. I sprayed it in my lock until all the black gunk flowed out. Then I opened the lock effortlessly, even better than before. This is probably the best product I have ever used to fix something. I'm still kind of amazed that it worked.

This stuff was a lifesaver on the Alcan. The locks on our RV pass through doors got full of road debris and dust, and if it hadn’t been for a can of this, we wouldn’t have been able to access them on our trip.

great product. order filled kinda slow.

Loosened a doorknob that was unused for many years. I needed it for a screen door lock that was rarely used, but still needed to stay working without a fight. Both cases, a light spray using the attached tube was tidy and quick. Saved me replacement parts and fuss with unmatched sets of house keys.

Works good. Recommend

I rarely come back to review things on amazon, but this has fixed 3 locks for me, 1 on my truck and 2 on the house, in the middle of winter they get stuck sometimes and its a recipe to break keys, I have tried cheaper products, and they work for like a week, been a month or 2 now, locks work in freezing cold, smooth, long lasting, no problem, best lock lubricant I have ever had

Probably the best lubricant for locks, not cheap but works brilliantly to make a old lock work like new. I researched lock lubricants before selecting this one and I realised you can’t put anything in a lock, it has to be designed for locks otherwise it can make more damage than help.

Before Houdini my front door top and bottom locks were extremely hard to get the key into and out of and the bottom lock would lock on its own if you slipped out for a moment without locking the door. We were worried the key would get stuck and break or the door would lock us out. After Houdini within seconds I put my key in and it slipped in like a hot knife through butter. The fix was instant. This is the real deal.

As good as it gets. The main door keyhole was starting to jam. Got some Houdini, sprayed in the keyhole and its been smooth riding since

This lubricant is amazing! I've used many different lubricants on door knobs in the past but all have failed resulting in replacing my door knob 4 times. As soon as I used Houdini, it started to work. I can insert the key, the pins in the lock are now working properly (I can hear them) and all is good! True test will be throughout the next winter. So far, I'm really amazed at how it performs. And its smells so good!
