Question: 1 / 400

What is the main difference between a single cylinder and a double cylinder deadbolt?

A single cylinder uses a key on both sides

A double cylinder uses a thumb turn

A single cylinder uses a key on one side, while a double cylinder requires a key on both sides

The distinction between a single cylinder and a double cylinder deadbolt primarily revolves around how they are operated in terms of key usage. A single cylinder deadbolt features a keyhole on one side and a thumb turn on the interior side. This design allows for easy locking and unlocking from inside the dwelling without needing a key. In contrast, a double cylinder deadbolt has keyholes on both sides, meaning that a key is necessary to unlock the door from both the inside and outside.

This feature of the double cylinder can provide an added layer of security in scenarios where a window or other means of entry is close to the door, as it prevents someone from unlocking the deadbolt from the inside if they gain access to that area. Understanding these differences is crucial for locksmiths when advising clients on the appropriate deadbolt type for their specific security needs.
