2. Setup and Key Identification
2.1 Identifying Your Lock Code
Before using your new replacement keys, it is essential to ensure they match your toolbox lock. The key code for your lock can typically be found in one of the following locations:
- On the Original Key: The code is often stamped directly onto the key itself.
- On the Lock Face: Look for the code engraved or printed on the visible part of the lock cylinder.
- Inside/Behind the Lock: Some locks have the code on a label or stamped directly onto the lock mechanism, which may require opening the toolbox or removing a panel to access.
- On the Cabinet/Door Label: For some toolboxes, the key code might be listed on a label affixed to the cabinet or door.

Figure 2: Where to Find Your Lock Code. This diagram illustrates common locations for lock codes, including on the key, lock face, inside the lock, and on a cabinet label.
Important Note: Key cuts can differ significantly between manufacturers, even if the numerical or alphanumeric codes appear similar. Always verify that the key code matches the specific manufacturer (e.g., Mac Tools) for which the key is intended.
2.2 Lubricating Your Lock
For optimal performance and to prevent stiffness or sticking, it is recommended to lubricate your toolbox lock mechanism before or during the first use of your new keys. Use the included 1 cc packet of Super Lube Multi-Purpose Synthetic Grease with Syncolon.
- Locate the keyhole of your toolbox lock.
- Apply a small amount of Super Lube directly into the keyhole. A tiny drop is usually sufficient.
- Insert your new key and turn it gently several times to distribute the lubricant throughout the lock mechanism.
- Wipe away any excess lubricant from the key and the lock face.

3. Operating Instructions
3.1 Locking and Unlocking Your Toolbox
- Insert the Mac Tools A8337 key fully into the lock cylinder.
- To unlock, turn the key clockwise (or counter-clockwise, depending on your lock mechanism) until the lock disengages.
- To lock, turn the key in the opposite direction until the lock engages.
- Remove the key.
Always turn the key smoothly and avoid excessive force. If the key feels stiff, refer to the Maintenance section for lubrication instructions.
4. Maintenance
4.1 Key and Lock Care
- Lubrication: Periodically apply a small amount of Super Lube or a similar high-quality lock lubricant to the lock mechanism (refer to Section 2.2). This helps prevent wear, corrosion, and ensures smooth operation.
- Cleaning: Keep your keys clean and free from dirt, debris, or corrosive substances. Wipe them with a soft, dry cloth if necessary.
- Storage: Store spare keys in a safe, dry place to prevent loss or damage.
- Avoid Force: Never force a key into a lock or apply excessive pressure when turning. This can bend or break the key, or damage the lock mechanism.
