Single-cylinder deadbolts are operated with a key from the outside of a home and a thumb turn from the inside. A double-cylinder deadbolt is operated with a key from both outside and inside the door. This offers a more foolproof security option against the burglar who relies on gaining access to a home by breaking through the door glass and turning the thumb turn to open the door. Always keep a key near a double-cylinder deadbolt, in case of fire or other emergency.
