Oklahoma Locksmith Practice Exam

What does the number on the face of a file cabinet lock represent?

1. Key identification number

2. Replacement key code

3. Manufacturer's serial number

4. Lock model number

The correct answer is: Replacement key code

The number on the face of a file cabinet lock typically represents the replacement key code. This code is essential for locksmiths and locksmithing technicians, as it allows them to identify the specific key that will operate that lock. When a key is lost or damaged, having the replacement key code enables the locksmith to create a new key that will work with the existing lock, facilitating a smooth and efficient service. Key identification numbers, manufacturer's serial numbers, and lock model numbers have their own specific applications and purposes. However, they do not directly correlate with referencing the specific key needed for a particular lock, which is why the emphasis is placed on the replacement key code in this context. Understanding this distinction is crucial for those involved in locksmithing, as it impacts their ability to service clients effectively.
