Pro-Tex-All Houdini Lock Lube

I was recommended this by a locksmith friend, where it does a good job at lubricating not just lock mechanisms, but a broad spectrum of things. Everything from spraying a foot of a RV tongue jack to mitigate rust to hitting hinges on cars. So far, it has done an excellent job, and I have bought multiple cans of this to ensure that outside locks are operable after heavy rains. Finding a specific lubricant for locks is hard, because the wrong oil can gum up things and require a time-consuming cleaning. I used the wrong lubricant on one lock, wound up having to completely take it apart down to the individual springs, soak in a degreaser, then use a correct lubricant to get things working correctly. Every so often, especially after heavy rains, this is something to use on padlocks, both on the lock cylinder, as well as both sides of the shackle. For deadbolts on gates, I like spraying this on the screws, as this acts as an anti-seize, ensuring that it can be taken apart in the future. It also is good for spraying in the keyholes. I have also sprayed it on rusty areas, which works well as a barrier against corrosion. Smell-wise, it doesn't smell really bad. My only wish is that they include more than one of the straw.

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.

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!

Love this product! Works great as a Lubricant.
