This manual provides essential information for the identification, use, and care of your CompX National PB551 Office Furniture Replacement Key. This key is designed to replace lost or damaged keys for office furniture locks within the CompX National Key Series PB001-PB634 range.
Key Identification and Setup
To ensure you have the correct replacement key, it is crucial to verify the lock code. The lock code determines the specific key required for your furniture lock.
- Locate the Lock Code: The lock code is typically stamped on your original key. If the original key is unavailable, the code may be found on the face of the lock cylinder itself.
- Verify Compatibility: This replacement key is specifically for the PB551 code within the CompX National Key Series PB001-PB634. Ensure the code on your lock or original key matches "PB551".

Operating Instructions
To operate your office furniture lock with the PB551 replacement key:
- Insert the Key: Gently insert the PB551 key into the keyway of the furniture lock. Do not force the key.
- Turn to Unlock/Lock: Once fully inserted, turn the key clockwise or counter-clockwise, depending on the lock mechanism, to engage or disengage the locking bolt.
- Remove the Key: After locking or unlocking, return the key to its original position (usually vertical) before carefully removing it from the lock.
Care and Maintenance
Proper care will extend the life of your replacement key and ensure reliable operation:
- Keep Clean: Periodically wipe the key with a soft, dry cloth to remove dust and debris. Avoid using abrasive cleaners or solvents.
- Avoid Bending: Do not apply excessive force or attempt to bend the key, as this can damage its structure and render it unusable.
- Proper Storage: Store the key in a safe place, away from extreme temperatures or corrosive materials.
- Lubrication (Optional): If the lock mechanism becomes stiff, a small amount of graphite lubricant or a specialized lock lubricant can be applied to the lock cylinder, not directly to the key. Consult the furniture manufacturer's guidelines for lock maintenance.
Troubleshooting
If you encounter issues with your replacement key, consider the following:
- Key Does Not Insert Fully:
- Ensure the key is oriented correctly.
- Check for obstructions in the lock keyway (e.g., debris, broken key fragments).
- Verify that the key code "PB551" matches your lock.
- Key Inserts but Does Not Turn:
- Confirm the key code "PB551" is correct for your lock.
- The lock mechanism may be jammed or require lubrication. Do not force the key.
- The lock itself may be faulty and require professional service or replacement.
- Key Feels Loose or Wobbly:
- This could indicate wear on the key or the lock cylinder. If the key is new, the lock may be worn.
If troubleshooting steps do not resolve the issue, contact the seller or a qualified locksmith for assistance.
