However, safety concerns are raised with double-cylinder deadbolts as it is more difficult to unlock the door from the inside when trying to escape in case of fire (because a key is required to open the locked door). Double-cylinder deadbolts are commonly used on doors with glass panels, or nearby windows, to prevent intruders from reaching through the glass to unlock the door (as a key is required to unlock the bolt from both the inside and outside of the door). The single-cylinder function is the most common, providing exterior security, but the thumb-turn provides safety for an easy exit in case of fire or other emergency. Single-cylinder deadbolts have a keyed-cylinder on the exterior side, and a thumb-turn on the inside. For thicker doors up to 2-1/2", specify during checkout.
