Is it necessary to change the mechanical lock to a fingerprint lock?

I feel very necessary, the main recommended reasons:

1, you can not have to bring the key, to avoid the embarrassment of forgetting the key can not go home.

2, you can unlock the door remotely, which is more convenient for the elderly, children or relatives.

3, no longer need to worry about lost keys! Installed fingerprint combination locks, we can get rid of the agony of going out and forgetting to bring the key, and when we arrive home, we only need to stretch out our fingers to open the door of our home, which is very convenient.
