Keysmart VS Keysmart ninja review is guaranteed to help you make the right decision. The polycarbonate and aluminium construction of the key ninja makes it flexible but easy to break.

The toughest thing about working as a guard is handling all the building keys assigned to me. I can’t lie; I have lost close to 50 keys while I’m off duty. Sometimes I leave them at the mall, on the train or in the park. On my lucky days I get to recover the keys but when I’m not I have to use the my finances to replace them, that’s just how my company policy works. I have lost a lot of money trying to replace the keys. The improvised metal key chain offered to me by the landlord has torn off most of my pockets and jacket pockets. This is why I set out to find the perfect solution.

 Key ninja VS Keysmart  – A Detailed comparison


When it comes to aesthetic, you can never go wrong with either of them. They are designed with round edges and a smooth body to keep sharp edges of your keys from pocking holes into your clothes, bags or scaring your skin.


You can expand the keysmart to hold up to 14 standard sized keys while the key ninja is expandable to fit up to 30 keys.


This is one of the major differences between the two. The keysmart is built using a high grade aluminium and good quality stainless steel while the key ninja is made of polycarbonate frames and stainless steel. The key ninja can break more easily and won’t last as long as the keysmart.


The keysmart has a simple loop where you can attach a bigger key of your car keys. The key ninja has 2 ED lights attached, a built in bottle opener and an s hook where you can attach larger keys, car keys and remotes.


The polycarbonate material of the key ninja makes it lighter and even less bulky when keys are assembled when compared to the keysmart.  The stainless steel and aluminium combo is perfectly durable and will last you for quite a while.

Maximum key length

For both holders, a maximum of 80 mm key length is required to make it more comfortable and pocket friendly when travelling.  The length of the key is measured from tip t tip. For installation length, it should be less than 76mm from the hole to the tip of the key.

The verdict

To make the right choice, take into consideration how many keys you have on your key chain. While the key ninja can accommodate plenty of keys and has desirable accessories, the keysmart will last you longer but won’t be able to hold most keys. I found that the key ninja is perfect for my job for its ability to accommodate all my keys at once.
