Explanation:
In key cutting, the shoulder refers to the part of the key that stops against the lock face when fully inserted, while the tip is the end of the key that enters the lock mechanism. These two stops are crucial in determining the correct length and shape of the key, ensuring it fits and operates smoothly in the lock. The other options mentioned are not relevant in the context of key stops.
Explanation:
An uncombinated key, also known as a key blank, refers to a key that has not been cut or coded to operate a specific lock. It serves as the raw material from which a finished key is made by cutting the grooves and ridges necessary to match a particular lock's configuration.
Explanation:
Running the cutter into the vise jaw is not advisable because it can damage the cutter and reduce its effectiveness over time. It's important to handle key machines carefully to maintain their performance and longevity.
Explanation:
Both the shoulder and the tip of the key can prevent it from deeper insertion into the cylinder than necessary. The shoulder can hit against the face of the lock, while the tip may come into contact with the back of the keyway.
Explanation:
When a key turns hard in a car door cylinder, it is often the result of an improperly bent rod. The rod connects the key cylinder to the door latch mechanism, and if it is bent incorrectly, it can cause friction and difficulty in turning the key. This can happen due to wear and tear over time or improper installation.
Explanation:
An associated master key is specifically designed to work with certain change keys based on constant cuts, allowing for a controlled access system within a facility.
Explanation:
An angularly bitted key has cuts made into the blade at various degrees of rotation from the perpendicular, allowing it to operate locks with non-standard pin arrangements.
Explanation:
A skeleton key typically operates a warded lock. These locks use a simple design where the key has to bypass wards, or obstacles within the lock, to turn the mechanism.
Explanation:
The length of the blade of a key blank corresponds to the number of pins that can be set within the lock. Different locks require keys with varying lengths to accommodate the specific number of pins they contain.
Explanation:
A Change key is designed to operate only one lock within a set or series of locks, typically used in a master key system where each lock has its unique key (Change key) but can also be operated by a master key. This setup allows for different levels of access within a building or facility.
Explanation:
An attendant's key in a hospital keying system is a selective master key, allowing authorized personnel access to specific areas within the facility while restricting access to others.
