Introduction
This manual provides essential information for the identification and proper use of your EasyKeys replacement key for CompX National A4360 locks. This key is specifically designed for use with file cabinets, desks, and cubicles that utilize the CompX National A4360 lock code.
Key Identification and Lock Code Verification
To ensure you have the correct replacement key, it is crucial to verify the lock code. The lock code determines the specific cut of your key.
Locating Your Lock Code
Your lock code can typically be found in one of the following locations:
- On the Original Key: The code is often stamped directly onto the key blade or head.
- On the Lock Face: For many locks, the code is engraved on the visible face of the lock cylinder.
- On a Label Inside/Behind the Lock: Some locks have a label with the code placed inside the cabinet or behind the lock mechanism.
- On the Cabinet/Door Label: Occasionally, the code may be on a label affixed to the cabinet or door itself.
Important Note:
Lock codes are manufacturer-specific. Even if codes appear similar, key cuts vary by brand. Always confirm that the manufacturer (CompX National) and the code (A4360) match your lock.

Compatibility: This key is compatible with CompX National A0100 - A7003 series locks, specifically for the A4360 code. It is also compatible with manufacturers such as Corry Jamestown, Steel-Age, and Brown-Morris for file cabinet locks.
Maintenance
This replacement key requires minimal maintenance. Keep the key clean and dry. Avoid using excessive force when inserting or turning the key, as this can damage both the key and the lock mechanism. If the lock mechanism becomes stiff, a small amount of graphite lubricant can be applied to the keyway. Avoid oil-based lubricants, as they can attract dirt and debris.
Troubleshooting
Key Does Not Turn
- Incorrect Key: Double-check that the lock code on your key matches the code on your lock.
- Obstruction: Ensure there are no foreign objects or debris in the keyway.
- Lock Mechanism Issues: If the key is correct and the keyway is clear, the lock mechanism itself may be damaged or jammed. Professional assistance may be required.
Key Is Difficult to Insert
- Alignment: Ensure the key is aligned correctly with the keyway.
- Debris: Check for any debris in the keyway that might be obstructing insertion.
- Bent Key: Inspect the key for any signs of bending or damage. A bent key should not be forced into the lock.
