2. Key Identification and Verification
Before using your replacement key, it is crucial to verify that the lock code and manufacturer match the product title (Hafele H5665). Incorrect key codes will not operate your lock.
To ensure compatibility, locate the existing lock code on your current key, the lock face, or on a label inside/behind the lock or cabinet/door. Refer to the image below for common locations.

Figure 2: Common locations to find your lock code. This diagram illustrates where to check for the alphanumeric code required to match your replacement key.
Important Notes:
- Lock codes are specific to the manufacturer. Always order by manufacturer and the exact lock code.
- Key cuts differ significantly between brands, even if codes appear similar.
3. Operating Instructions
Using your EasyKeys replacement key is straightforward:
- Insert the key fully into the lock cylinder.
- Turn the key clockwise or counter-clockwise (depending on the lock mechanism) to engage or disengage the lock.
- Remove the key once the lock is in the desired position (locked or unlocked).
4. Maintenance
To ensure the longevity and smooth operation of your key and lock:
- Keep the key clean and free from dirt or debris.
- Avoid bending or applying excessive force to the key.
- If the lock mechanism becomes stiff, a small amount of graphite lubricant can be applied to the key or directly into the keyway.
5. Troubleshooting
If your replacement key does not operate the lock:
- Key Does Not Insert Fully: Check for obstructions in the keyway. Ensure the key is oriented correctly.
- Key Inserts but Does Not Turn: Double-check that the lock code on your key matches the code on your lock. Verify the manufacturer. The lock mechanism might be jammed or worn; try applying lubricant.
- Key Turns but Lock Does Not Engage/Disengage: The internal lock mechanism may be faulty or damaged. This issue is typically with the lock itself, not the key.
If issues persist after troubleshooting, contact the lock manufacturer or a professional locksmith for assistance.
