Introduction
This document provides essential instructions for the proper identification and use of your EasyKeys Replacement Key for CompX National D008 locks. Please read this manual carefully to ensure correct application and to maintain the functionality of your key.
Key Identification
Before attempting to use your replacement key, it is crucial to verify that the lock code and manufacturer match the specifications of your key. This replacement key is specifically designed for CompX National locks with the D008 code. Incorrect key usage can damage the lock or the key itself.

Image Description: This diagram illustrates common locations where a lock code can be found. These include directly on an existing key, etched or printed on the face of the lock cylinder, on a label positioned inside or behind the lock mechanism, or on a label affixed to the cabinet or door itself. It also includes important notes emphasizing that lock codes are manufacturer-specific and key cuts differ by brand, even if codes appear similar.
To confirm your lock code, refer to the methods shown in the image above. Ensure the code found on your lock or existing key precisely matches 'D008' and that the lock is manufactured by CompX National.
Usage Instructions
Inserting the Key
- Gently insert the key into the lock's keyway. Do not force the key.
- If the key does not slide in smoothly, ensure it is oriented correctly. The key's bitting (the cut edge) should align with the lock's internal mechanism.
Operating the Lock
- Once fully inserted, turn the key clockwise or counter-clockwise, depending on the lock mechanism, to engage or disengage the lock.
- The key should turn smoothly without excessive resistance.
- After the lock is operated, return the key to its original position and gently remove it.
Care and Maintenance
- Keep the key clean and free from dirt or debris.
- Avoid exposing the key to harsh chemicals or extreme temperatures.
- Store the key in a safe place to prevent bending or damage to its cuts.
- Do not use the key for purposes other than operating its intended lock.
Troubleshooting
- Key Does Not Insert Fully: Ensure the key is oriented correctly. Check the lock's keyway for any obstructions or debris.
- Key Does Not Turn: Verify that the lock code on your key matches the lock. Ensure the key is fully inserted. The lock mechanism might be jammed or require lubrication.
- Key Feels Stiff: A small amount of graphite lubricant (not oil-based) can be applied to the key or directly into the keyway to improve smoothness.
- Lock Still Not Working: If issues persist after troubleshooting, re-verify the lock code and manufacturer. If confirmed correct, the lock mechanism itself may require professional inspection or replacement.
