2. Key Identification and Verification
Before attempting to use your new replacement key, it is crucial to verify that the lock code and manufacturer match the specifications of this product. Incorrect key codes or incompatible manufacturers will prevent the key from functioning correctly.
2.1 How to Find Your Lock Code
The lock code is typically found in one of several locations. Refer to the image below for common places to locate your lock code:

Image 2.1: Diagram illustrating common locations for lock codes. Codes can be found directly on the original key, on the face of the lock cylinder, on a label inside or behind the lock mechanism, or on a label affixed to the cabinet or door near the lock.
- On the Original Key: The code is often stamped directly onto the head or shaft of the existing key.
- On the Lock Face: Some lock cylinders have the code engraved on their visible face.
- Inside/Behind the Lock: For cabinet or drawer locks, the code may be on a sticker or engraved on the lock body itself, accessible when the lock is removed or the drawer/door is open.
- On a Cabinet/Door Label: Occasionally, the lock code is noted on a label attached to the furniture or door where the lock is installed.
Important Notes:
- Always order by manufacturer and lock code. Lock codes are specific to manufacturers.
- Key cuts differ significantly between brands, even if the codes appear similar. Ensure both the code and the manufacturer (CompX Chicago) are correct.
3. Usage Instructions
Once you have verified that your lock requires a 2402X key for a CompX Chicago lock, follow these steps to use your replacement 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.
- 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 engaged or disengaged, return the key to its original vertical or horizontal position before gently pulling it out.
If the key does not insert smoothly or turn easily, do not force it. Refer to the Troubleshooting section.
4. Care and Maintenance
To ensure the longevity and proper function of your EasyKeys Replacement Key, consider the following maintenance tips:
- Keep Clean: Periodically wipe the key with a soft, dry cloth to remove dirt or debris.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals, as these can damage the brass material.
- Proper Storage: Store the key in a dry place, away from excessive moisture or extreme temperatures.
- Do Not Bend: Avoid bending or applying excessive force to the key, as this can alter its shape and prevent it from working correctly.
5. Troubleshooting
If you encounter issues with your replacement key, please review the following common problems and solutions:
- Key Does Not Insert Fully:
- Ensure the keyway is clear of obstructions (e.g., dirt, debris).
- Verify that the key code (2402X) and lock manufacturer (CompX Chicago) are correct for your specific lock. An incorrect key will not fit.
- Key Inserts but Does Not Turn:
- Confirm the key code and manufacturer match your lock.
- The lock mechanism might be jammed or require lubrication. Consult a locksmith if the lock itself is faulty.
- Ensure the key is fully inserted before attempting to turn.
- Key Feels Stiff or Difficult to Turn:
- Apply a small amount of graphite lubricant (specifically for locks) into the keyway. Do not use oil-based lubricants.
- Gently wiggle the key while applying slight turning pressure.
If problems persist after following these steps, it is recommended to consult a professional locksmith or contact EasyKeys customer support.
