Introduction

The CompX Chicago KH10 Tubular Replacement Key is designed to provide a precise fit for locks requiring the KH10 series key. This manual outlines essential information for identifying the correct key, understanding its specifications, and ensuring proper usage and maintenance to extend its lifespan.

Key Identification

To ensure you have the correct replacement key, it is crucial to identify the lock code. This code is typically stamped on your original key or directly on the face of the lock cylinder if the original key is lost. The KH10 key is part of the CompX Chicago Key Series KH1-KH150 and is cut on a D137-CLC key blank.

Specifications

Usage and Application

The KH10 tubular replacement key is designed for use with CompX Chicago locks that specify the KH10 key code. To use the key, insert the tubular end into the lock cylinder, ensuring the key's grooves align with the pins inside the lock. Once fully inserted, turn the key clockwise or counter-clockwise as required to engage or disengage the lock mechanism. Do not force the key if it does not turn smoothly.

Maintenance

Proper maintenance can significantly extend the life of your key and the lock it operates.

• Cleaning: Periodically wipe the key with a dry, soft cloth to remove dirt and debris. Avoid using abrasive cleaners or solvents.
• Lubrication: If the lock mechanism becomes stiff, apply a small amount of graphite lubricant or a specialized lock lubricant into the keyway. Do not use oil-based lubricants as they can attract dust and gum up the mechanism.
• Storage: Store the key in a dry place, away from extreme temperatures and corrosive materials.
• Avoid Bending: Do not apply excessive force or attempt to bend the key, as this can damage its structure and render it unusable.

Troubleshooting

If you encounter issues with your replacement key, consider the following common problems and solutions:

• Key Does Not Insert Fully: Check for obstructions in the lock's keyway. Ensure the key is oriented correctly.
• Key Inserts But Does Not Turn: Verify that the key code matches your lock. The lock mechanism might be jammed or require lubrication. Do not force the key.
• Key Feels Loose or Wobbly: This could indicate wear on either the key or the lock cylinder. If the key is new, the lock might be worn.
• Key Breaks in Lock: This typically occurs due to excessive force or a worn key/lock. Professional assistance may be required to remove the broken piece.
