4PCS Locking Car Tire Valve Stems Caps, Anti-Theft Auto Wheel Valve Stem Covers with O Rubber Seal, Universal Stainless Tyre Air Stems Cover for Cars, Bicycles, Motorcycles (Black)

I have a standard looking sedan and it pleases my to have a small touch of color on the wheels. They were easy to put on, the tightening with the Allen wrench makes me feel secure that no one will be able to tamper with my tires. The stem covers feel solid and look good.

This is one of my favorite purchases! The color pops really nice with my car and rims, and the locking aspect is nice. Granted the tool isn't that unique but at least most people don't walk around with on so I have a little more piece of mind.

I kept losing air in my work van tire , I thought I ran over a nail or something then I remembered a cap was missing to my valve stem so I decided to order some caps the next day i found out I had a leak in my old valve stem because after I put the new valve stem cap on ,the leak stopped completely, plus they lock so I never have to worry about theft or caps that fall off . I would highly recommend these caps to anyone. Great fit, great quality.

Not exactly "locking" but they do their job, are low profile and look very nice at a great price.

I was tired of coming home from different places that I had my car parked at and seeing a missing valve stem cap or caps. I guess people can't be bothered to go buy their own. So I purchased these Dickno caps to keep the honest people out there from stealing mine or at least slow them down. With the recessed Allen heads and the included Allen wrench my valve stem caps are no longer missing after a trip to a store.

This product is advertised as a 'security valve cap', which one would think that these caps have the ability to prevent them from being removed from a valve stem without a special tool. It turns out that these are just a set of aluminum valve caps that have a hex indent on the tip, in which an Allen key (included) can be used to tighten the cap further than you normally would by simply hand tightening them.There are no locking mechanisms or set screws to prevent the caps from being removed by normal means. They may have a smooth texture on the outside of them, making it more difficult to remove them if they're slippery, which would then be aided in removal by using the Allen key, but other than that 'security' feature, these are just shiny metal valve caps.If you want these for looks? They look cool. But if you want these for security purposes? They will fail in that aspect.Overall, these are being marketed as a security device for tire valve stems, but that is false advertising."Caveat emptor"

Era lo que yo esperaba muy bonitas y seguras
