Nowadays, almost everyone has a large bunch of keys. It takes our bag or pocket a lot of space. The portable key can help us to save space, because the handle of the key is folded at ordinary times. The handle can be opened when we use the key to open a lock. The portable key may help us to live a more comfortable life.
