Double Cylinder Function: Double cylinder deadbolts are keyed on both sides of the door and are only locked and unlocked via a key. Often times they are used on doors where glass is near the door that could be easily broken and the thumbturn on a standard single cylinder lock would be accessible. Caution: Double Cylinder locks can pose a safety hazard in times of emergency due to requiring a key to unlock. Please check local codes before installing.
