Product Overview
This manual provides essential information for the Hudson LL625 Replacement Key, part of the Hudson Key Series LL001-LL853. This key is designed as a direct replacement for lost or damaged keys for compatible Hudson and Harcor wafer locks.

Figure 1: Hudson LL625 Replacement Key. This image displays the key's head, which is circular and stamped with "MADE IN U.S.A." along the top curve and "LL001" in the center. The key's blade extends downwards, featuring a standard cut for wafer locks.
Important Note: To ensure you order and use the correct replacement key, the lock code is crucial. This code is typically stamped on your original key or directly on the face of the lock itself if the original key is unavailable. This key is custom cut on an IN8 key blank.
Setup and Key Identification
Proper identification of your lock's code is the only setup required for this replacement key. The key itself does not require any installation beyond being the correct match for your lock.
Identifying Your Lock Code:
- Check Original Key: If you still possess your original key, the lock code (e.g., LL625) will be stamped directly onto it.
- Inspect the Lock Face: If the original key is lost, locate the lock you intend to open. The lock code is often stamped on the visible face of the lock cylinder or housing.
- Verify Compatibility: Ensure the identified code matches the LL625 series for this replacement key. This key is specifically designed for Hudson and Harcor wafer locks within the LL001-LL853 series.
Using a key with an incorrect code may damage the lock or the key itself.
Operating Instructions
Once you have confirmed that the Hudson LL625 Replacement Key matches your lock code, its operation is straightforward.
Using the Key:
- Insert the Key: Gently insert the key into the keyway of the lock cylinder. Do not force the key. It should slide in smoothly if it is the correct key.
- Turn the Key: Once fully inserted, turn the key clockwise or counter-clockwise (depending on the lock mechanism) to engage the locking or unlocking mechanism.
- Remove the Key: After the lock has operated, return the key to its original insertion position (usually vertical) before gently pulling it out.
If the key does not insert smoothly or turn easily, do not force it. Refer to the Troubleshooting section.
Maintenance
The Hudson LL625 Replacement Key requires minimal maintenance to ensure its longevity and proper function.
- Keep Clean: Periodically wipe the key with a soft, dry cloth to remove dirt, dust, or grime. Avoid abrasive cleaners or harsh chemicals.
- Avoid Bending: Store the key in a manner that prevents it from being bent or twisted, which can alter its shape and prevent it from working correctly.
- Lubrication (for lock): If the lock mechanism becomes stiff, apply a small amount of graphite lubricant or a silicone-based lock lubricant directly into the lock's keyway, not on the key itself. This can improve the key's smooth operation.
- Proper Storage: Store the key in a dry place, away from extreme temperatures or corrosive environments.
Troubleshooting
If you encounter issues with your Hudson LL625 Replacement Key, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
