Nite Ize S-Biner MicroLock Stainless Steel - S-Biner with Locking Dual Sided Gates - Keep Keys Secure with Carabiner Key Holder - Black (2 Pack)

This is definitely a weird one but After experiencing engine cutouts due to electrical connection issues on my ignition coil harness I tried thinking of a way to brace my ignition coil harness on both sides so that I didn't have to butt splice in a new connector on a 13 year old vehicle, as I figured one Jerry rigged connection was better than 8 butt splices. The regular zip tie to lock in the broken tab wasn't getting enough pressure, however this was the only thing that would have worked probably and it's not pretty but they came in clutch.

I bought these mainly to use on my keys. After that first purchase I bought them in different sizes and use them for adding tags to items, attaching a purse zipper in a way the zipper could not be easily opened, holding chains together on stall doors and gates, once in an emergency to hold a horses bridle together. Always have one on my keys!

The small size is great for a small ID fob, tracker, or a few keys. I'm using it with a slightly larger Nite Ize locking clip so I can separate my house keys from my car keys easily. The locking function is great. It takes some effort to open, so I'm very sure it will never open accidentally and come off my key ring like others have. It clips on easily and is small enough that it doesn't add too much bulk to my pocket.

Bought these as a way to keep our luggage and backpacks closed while traveling is Europe. They worked wonderful. I love that i can keep them for that or use them in a handful of different way. Wonderful purchase

Sometimes it looks like I robbed a janitor. Work keys, several vehicles, padlocks, you name it. When I'm going shopping or to a function, I don't like to have a big pocket full of metal and I'm not the guy that will clip them to my beltloop. I only take the key fob and leave the bulk in the truck, but need to reattach them when I get back in because I use several different vehicles. My previous carabiner would twist up and manage to separate when I didn't want them to. This tiny locking clip is perfect, exactly what I was looking for. You clip things together, then twist the lock to block the latch from opening. When I want to leave the bulk behind, one twist lets me shed the rest properly.

I have used this for 1 month and it’s exactly what I needed. I have not lost a key due to separating from key ring. This year I lost one that came off backup key and one that separated off magnet. I needed a key ring that allowed switching of keys easier as I have 4 drivers living with me and we switch cars depending on what our needs are and this locks the keys in place. Functionally this is perfect, I hope it lasts. Time will tell

These things are great for attaching small items and the locking mechanism is super simple. I use these to attach my ear bud case to my backpack when traveling and have zero concern that they will fall off.

Only put in three due to price being so high for only two
