I work a strict schedule with a major mobile cab service provider in my city. To add on that, have a second job, which means that I have little time to do any housework.  I often hire a cleaning lady to take care of the work. She ends up locking my keys in the house most of the times. I was forced to carry around a bunch of keys to work. Because of this, I often found myself needing to replace my locks and make copies. I looked online and this keysmart vs carbocage keycage comparison helped me find the solution.

Keysmart VS Carbocage keycage – A Detailed Comparison

The shape of the carbocage is much different with one side being wider than the other. The materials on the body and bots are different, but it also feels strong and weightless.

When expanded, the keysmart can hold up to 14 standard sized keys, which is super convenient. The keys are installed on both end of the holder. The arrangement does not matter as long as both sides have an even width.

The carbocage keycage also has installation screws on both sides. You can install keys on each side without worrying if the thickness of the keys matter.
