Nite Ize S-Biner MicroLock, Locking Key Holder

Colours to differentiate keys from one another. Holds keys in place when lock is turned. We attached to house and car keys.

I work at a college facility and have to carry a large set of master keys daily, I Purchased these as a means to organize my key ring without having to worry about losing my job essential keys. I've had them for a month now and they are holding up great for being Aluminum. Its also nice being able to know exactly what key I need for whatever door I need to get through thanks to the multi bright colors. I've enjoyed them to the point that I had to deck out my at home key ring too. Anything Nite Ize Highly recommended.

Here's the deal, I ordered these as open package, but I could tell that only one was tried. As I tried to get keys on these, they were so tight that they actually broke! The spring breaks right off. I was also angry to find these for $3 and change at my local hardware store. These are worthless. Don't waste your money!

The lock ability (and the color) sold me on this carabiner. Clips easily on the larger ring of the collar as well as clips onto dog tags with ease. The lock is basically easy to turn but is recessed so that the dog shouldn’t be able to catch it on anything. Using this to take tags on and off is so much easier than trying open the small ring to go around the big ring. Even replacing a yearly tag takes much effort.

This was perfect for securing a broken shoulder strap on a small backpack. It was small enough to be unobtrusive and sturdy enough to do the job. Stronger than I thought possible to be so small. I can see many uses for these s-binders—including attaching keys to bags, belts, wrist straps & more.

Pros:- Lock helps prevent accidental openingCons:- Flanges can become loose and come outThis is a great improvement over the non-locking version of the S-Biner. The non-locking versions had a habit of opening and allowing my keys to fall off when in my pocket. This has led to some missing keys. The small little plastic locking bar helps prevent this from happening, and is a welcome change. However, the flange seem to be a bit more flimsy. Not sure why, but every now and then, the flange will come loose and fall out. This can be problematic since my keys are no longer attached, and I have to hopefully find the flange. I wanted to like these more, but I truly can't recommend them.
