Keychain detachable chamber

Descripción

This is a detachable keychain with a storage chamber. One part holds the car keys and the other part could hold the house keys. It is convenient to be able to remove the house keys without turning the car off. Or the car keys could be given to anyone to drive while keeping the house keys with those staying at home. The keychain has a chamber with the thread reversed. It's one way to keep anyone from opening it, they will be tightening it even more if they try. It's psychological :)
