If you lose a mechanical key, changing the electronic lock code does not revoke the lost key's access. Consider replacing the lock to ensure security.
The Aqara Smart Lock U100 and U50 offer advanced security features, but if a mechanical key is lost, it's essential to address the risk separately. Consult a professional to assess the lock and determine the best course of action.
Before ordering a new lock, check with your building manager to ensure that the replacement lock complies with building regulations and guidelines.
