Free ALOA Key Identification and Machines Questions and Answers — Questions and Answers
Question 1: What is an uncombinated key called?
- A key base
- A key blank (Correct answer)
- A non-key
- A practice key
Correct answer: A key blank
Explanation: <br> 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.
Question 2: When using a key machine, running the cutter into the vise jaw:
- is advisable to do
- will speed up the process
- will dull the cutter and reduce its efficiency (Correct answer)
- None of the above
Correct answer: will dull the cutter and reduce its efficiency
Explanation: <br> 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.
Question 3: The 2 most common key stops are :
- Blade and v-cut
- Shoulder and tip (Correct answer)
- Bow and blade
- Keyway grooves and bittings
Correct answer: Shoulder and tip
Explanation: <br> 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.
Question 4: When a key turns hard in a car door cylinder, it is often the result of:
- An improperly bent rod (Correct answer)
- A screwdriver that was shoved into it
- A broken lock
- Bugs in the lock
Correct answer: An improperly bent rod
Explanation: <br> 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.
Question 5: A Change key is a key that:
- opens all or most locks in an entire building
- will usually operate only one lock in a series. (Correct answer)
- is normally used by the builder's personnel for a temporary period during construction.
- is used to remove the central core from a removable core cylinder.
Correct answer: will usually operate only one lock in a series.
Explanation: <br> 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.
Question 6: The length of the blade of a key blank indicates:
- How much the key costs
- What the key is made of
- The number of pins within the lock (Correct answer)
- How secure a lock is made
Correct answer: The number of pins within the lock
Explanation: <br> 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.
Question 7: A skeleton key usually operates:
- A tumbler lock
- Handcuffs
- A mortise lock
- A warded lock (Correct answer)
Correct answer: A warded lock
Explanation: <br> 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.
Question 8: What is an attendant's key?
- A key used by the patients in the hospital
- A key used by the hospital staff to access all areas
- A key used by visitors to enter the hospital premises
- A selective master key used in a hospital keying system (Correct answer)
Correct answer: A selective master key used in a hospital keying system
Explanation: <br> 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.
Question 9: What does an angularly bitted key refer to?
- A key with cuts made into the blade at various angles from the perpendicular (Correct answer)
- A key with cuts made into the blade at various depths
- A key with only one cut made into the blade
- A key with a smooth blade and no cuts
Correct answer: A key with cuts made into the blade at various angles from the perpendicular
Explanation: <br> 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.
Question 10: What is an associated master key?
- A master key that opens all locks within a building
- A master key that operates only one lock in a series
- A master key that can open any lock in the same region
- A master key that has particular change keys related directly to its combination through the use of constant cuts (Correct answer)
Correct answer: A master key that has particular change keys related directly to its combination through the use of constant cuts
Explanation: <br> 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.
Question 11: What parts of the key most commonly stop it from deeper insertion in the cylinder than is necessary?
- The shoulder
- The tip
- The bow
- A and B (Correct answer)
Correct answer: A and B
Explanation: <br> 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.
