The term "Ward" refers to a specific feature in the design of a lock that serves to prevent tampering and enhance security. Wards are obstacles or obstructions that are strategically placed within the lock to restrict the movement of unauthorized keys. By implementing a warded design, the lock ensures that only a correctly shaped key can bypass these barriers and operate the locking mechanism. This approach to lock design is effective in deterring picking and manipulation, making it a key element of enhanced security in various types of locks.

The other terms, while related to lock mechanics, do not specifically refer to structures meant to prevent tampering. A chamber is generally a part of a lock where pins are housed, and while pins are essential for the locking mechanism, they do not serve the same obstructive purpose as wards. A retainer refers to a component that holds certain parts of the lock in place but is not specifically designed to obstruct tampering. Therefore, "Ward" is the most appropriate term in the context of enhancing lock security against unauthorized access.
