Small fit my Application great


Smaller and thinner than I expected. Time will tell to see how good the quality if it lasts a long time.


Look’s good 💪🏻


It is great at what it does, it is definitely better than some other quick disconnects out there.

Solid choice for quick key changes to reduce bulk

On any given day, I could need one of three sets of keys, and one of two car key fobs, plus key chain scan cards for medical offices. Two sets go on my Key Smart, and I initially had one Quick Disconnect for one of my car key fobs. I decided to get two more, one for the third set of keys and one for the other end of my KeySmart (opposite the initial car key fob Quick Disconnect). It's nice now to just quickly change out what keys I'm using and reduce the bulk in my pocket and the potential noise while walking.
