### A Kwikset Titan has a MACS of:

• A.

5

• B.

4

• C.

7

• D.

9

B. 4
Explanation
A Kwikset Titan has a MACS (Maximum Adjacent Cut Specification) of 4. This means that the difference between any two adjacent cuts on the key cannot exceed 4. The MACS is a measure of the key's security and determines how difficult it is for someone to pick or manipulate the lock. A lower MACS value indicates a higher level of security, as it limits the possible combinations of key cuts. Therefore, a MACS of 4 indicates that the Kwikset Titan is relatively secure and harder to pick compared to higher MACS values.

### How many sets of pintumblers are in a typical pin tumbler house door lock?

• A.

3 or 4

• B.

5 or 6

• C.

11 or 12

• D.

7 or 8

B. 5 or 6
Explanation
A typical pin tumbler house door lock consists of multiple pin tumblers, which are small cylindrical pins that move up and down within the lock cylinder. Each pin tumbler is paired with a corresponding driver pin, and the combination of these pins determines the lock's key code. Generally, there are multiple pin tumblers in a lock, with each set consisting of a pin tumbler and a driver pin. The question asks how many sets of pin tumblers are in a typical lock, and the correct answer is 5 or 6, indicating that there are 5 or 6 pairs of pin tumblers and driver pins in the lock.

### Spool and Mushroom pins:

• A.

Make keys easier to duplicate

• B.

Can hinder normal picking attempts

• C.

Make a lock easier to pick

• D.

Make keys harder to duplicate

B. Can hinder normal picking attempts
Explanation
Spool and mushroom pins can hinder normal picking attempts. These types of pins are designed to create false sets and increase the difficulty of picking a lock. When a pick is inserted into the lock, these pins will catch on the pick, causing the pins to bind and giving the appearance of a set pin. This can confuse and frustrate a picker, making it more challenging to successfully pick the lock. Therefore, spool and mushroom pins can act as a deterrent to picking attempts.

### A key in knob lock whose default position is that both knobs are locked and require that a key be used for unlocking is :

• A.

A classroom lock

• B.

A function lock

• C.

An institution lock

• D.

A school lock

C. An institution lock
Explanation
An institution lock refers to a type of key in knob lock that is commonly used in large organizations or institutions such as universities, hospitals, or government buildings. These locks typically have a default position where both knobs are locked, requiring the use of a key to unlock them. This design ensures better security and control over access to certain areas within the institution. Therefore, an institution lock is the most appropriate term to describe this type of lock.

At least one -1 oe 1-4 adjacent cuts

A. A sum total of cut depths that must equal an even number
Explanation
The correct answer is that General Motors' 10 cut wafer sidebar locks have a sum total of cut depths that must equal an even number. This means that when you add up all the cut depths in the lock, the result must be an even number. This requirement ensures that the lock is properly aligned and functions correctly.

### The 2 most common key stops are :

• A.

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.

• C.

It is usually used in conjunction with a rim lock, which is a surface-mounted lock that is attached to the inside face of the door.

This type of key is essentially a blank slate, ready to be customized according to the needs of the lock it will be used for. It does not have any cuts or combinations on it, making it a blank key that can be shaped and cut to match a particular lock.

• A.

True

• B.

False

B. False
Explanation
Running the cutter of a key machine into the vise jaw is not necessary or recommended.

### A electromagnetic lock can exert a holding force of 15000 pounds

• A.

True

• B.

False

B. False
Explanation
An electromagnetic lock is a type of lock that uses an electrical current to create a magnetic field, which then holds the lock in place. While electromagnetic locks can exert a significant holding force, it is highly unlikely that they can exert a force of 15000 pounds. Such a force would be extremely powerful and not typically found in standard electromagnetic locks, making the statement false.

### A combination lock requirew a key to be opened

• A.

True

• B.

False

B. False
Explanation
The statement is incorrect because a combination lock does not require a key to be opened. Instead, it requires a specific sequence of numbers or symbols to be entered in the correct order to unlock it. Keys are typically used for traditional locks, where a physical key is inserted into a lock mechanism to open it. However, combination locks operate differently and do not rely on keys for their functionality.

### A rubberband can assist in opening some types of locks

• A.

True

• B.

False

A. True
Explanation
Rubberbands can be used as a tool to open certain types of locks. By wrapping the rubberband around the lock and applying tension, it can create enough friction to turn the lock mechanism and unlock the door. This technique is commonly known as the "rubber band lock picking" method and is often used in emergency situations or by locksmiths. Therefore, the statement "A rubberband can assist in opening some types of locks" is true.

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.
