Overview
This manual provides instructions for the CompX National A3496 replacement key, designed for specific toolbox and file cabinet locks. This key is a custom-cut replacement for lost or damaged original keys.
Key Identification and Setup
Before using your new replacement key, it is essential to verify that it matches your lock.
Identifying Your Lock Code
The correct key for your lock is determined by its unique lock code. This code is typically stamped in one of the following locations:
- On your original key (if available).
- On the face of the lock cylinder itself.

Compatibility

Important: This key is NOT compatible with architectural mailboxes.
Operating Instructions
Once you have confirmed the key code matches your lock, insert the key fully into the lock cylinder.
- Insert the key into the keyway of the lock. Ensure the key is fully seated.
- Turn the key clockwise or counter-clockwise, depending on the lock mechanism, to engage or disengage the locking bolt.
- Remove the key after the lock has been operated.
Do not force the key if it does not turn smoothly. Forcing the key can damage both the key and the lock.
Maintenance
Proper care can extend the life of your replacement 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 keyway. Do not use oil-based lubricants as they can attract dirt.
