The key release is made using NASA space development technology and can withstand a tension of up to 200 kg.

By gently pressing the protrusion and pulling it out, the rings can be removed separately, allowing you to carry two types of keys together, such as an engine key and a trunk key, or a garage key and a front door key, and use them separately as needed.

It is also very convenient as it can be easily removed when attaching your car keys to a key bag (sold separately).
