What is the difference between single cylinder and double cylinder deadbolt locks?

• Single cylinder deadbolt locks are typically used on a front or back exterior door and are operated with a key from the exterior of the home and a thumb turn from the interior.
• Double cylinder deadbolt door locks are typically used on a front or back exterior door and are operated with a key from both the exterior and interior of the home. Double cylinder deadbolts are recommended when a window is in close proximity to the door. The interior keyway prevents an intruder from accessing your home by breaking the glass and turning the thumb turn to open the door.
