Unlike many interior smart locks on the market, this model includes a mechanical override key, giving you a reliable backup option if the batteries go flat or in other unexpected situations. This is a practical feature that many similar interior smart locks do not offer.

For your safety, always keep an override key accessible outside the room to prevent accidental lock-outs.
