Keychain technology doesn't seem like anything that can be improved upon. Until we all have digital keys, the Keyport Slide is designed for that.

Keyport Slide is designed to arrange your keys into an easy-to-use bunch that requires no clinking together. That means that your keys will not scratch up your other pocketed items as it did before. It will make your keys a heavier weight, probably. It may be worth it for a quick slide-out, and your key is ready to go.

So far, no price or availability is ready as yet.
