The tension wrench is inserted at the bottom of the lock. This is because the tension wrench is used to apply pressure to the lock's core or cylinder, while the lock is being picked. By inserting the tension wrench at the bottom, it allows for better control and manipulation of the lock's internal components, increasing the chances of successfully picking the lock.

When a lock is picked backwards, the plug spinner is required. The plug spinner is a tool used to rotate the lock cylinder in the opposite direction to reset the pins and allow the lock to be opened. This tool is essential in quickly and efficiently opening a lock that has been picked in the wrong direction.

The 3/4 pick is used for raking. Raking is a technique used in lock picking where a pick with multiple peaks is inserted into the lock and then quickly moved up and down. This technique is used to manipulate the pins inside the lock and try to set them all at once, allowing for a quicker and more efficient way to pick the lock.

The pins inside a lock are located at the top. This is because the pins are responsible for securing the lock and preventing it from being opened without the correct key. When the correct key is inserted into the lock, it aligns the pins at the top, allowing the lock to be turned and opened.

The pick is initially inserted in the center.

The correct answer is 3/4. A 3/4 pick is used for raking.

The correct answer is using a special piece of metal with a hook to pull the plunger or using the credit card method depending on plunger orientation. This method is considered the most covert because it does not involve any loud or forceful actions like door kicking or hacksaw. Instead, it relies on a specialized tool or a credit card to manipulate the lock mechanism quietly and without causing any damage to the door or lock. This allows the intruder to breach the lock without attracting attention or leaving any obvious signs of forced entry.

When a security pin is picked, the keyway moves slightly forward. This movement occurs because the security pin, which is designed to prevent the lock from being easily picked, is pushed up and aligned with the shear line. As a result, the keyway moves forward, allowing the lock to be opened.

A lightweight tension wrench is used for high security locks because it allows for more precision and control while picking the lock. High security locks require delicate manipulation, and a lightweight tension wrench provides the necessary finesse to avoid damaging the lock or breaking the pins inside. This type of tension wrench is designed to be less forceful, allowing the locksmith to apply just the right amount of pressure to set the pins and unlock the mechanism.

Warded picks are used on locks with indifferent looking keyways. Warded locks have a simple mechanism with obstructions called wards that prevent the wrong key from turning. Warded picks are designed to bypass these wards and manipulate the lock to open it. They have a flat, thin shape that allows them to navigate through the wards and engage the lock's mechanism. This makes warded picks the appropriate choice for locks with indifferent keyways.
