Abstract
A door lock is provided with a biometric sensor and a key cylinder. The biometric sensor is protected by being positioned on a shield, and such that the sensor is not exposed to damage by being on the front face of the door lock. The shield extends vertically downwardly from the remainder of the front face of the door lock, and the sensor is mounted to an inner face of the shield. Thus, the sensor is spaced away from a door when the door lock is mounted on a door. A finger may be inserted into a space between the sensor and the door, and the sensor can then capture information about the fingerprint. This information can be compared to expected fingerprints, and entry into a building can be granted based upon a recognition of this fingerprint.
