1. Introduction and Product Overview
This manual provides essential instructions for the proper identification and use of your EasyKeys replacement key for Weather Guard truck toolboxes, specifically for the K055 lock code. This key is designed to replace lost or damaged keys for Weather Guard and Knaack truck toolbox locks within the K001-K100 series, particularly for models manufactured prior to 2005 that utilize a square silver key and red pushbutton lock mechanism.
Ensuring you have the correct key code is crucial for proper functionality. Please follow the instructions carefully to verify compatibility before use.

2. Key Identification and Setup
Before using your new replacement key, it is critical to verify that the lock code on your toolbox lock matches the K055 code of this key. Lock codes are manufacturer-specific, and even similar-looking codes may have different key cuts. This key is compatible with Knaack and Weather Guard truck toolbox locks in the K001-K100 series.
How to Find Your Lock Code:
Your lock code can typically be found in one of the following locations:
- On the Existing Key: If you have an original or duplicate key, the code is often stamped directly on the key blade or head.
- On the Lock Face: The code may be engraved or printed on the visible face of the lock cylinder.
- On a Label Inside/Behind the Lock: For some toolbox models, the code might be on a sticker or label located inside the toolbox near the lock mechanism, or directly behind the lock assembly.
- On the Cabinet/Door Label: Less common, but some manufacturers place the lock code on a label affixed to the toolbox cabinet or door itself.

Important Notes:
- ⚠ Lock codes are specific to the manufacturer. Always order by manufacturer and verify the code.
- ⚠ Key cuts differ significantly between brands, even if codes appear similar.
3. Operating Instructions
Once you have confirmed that your toolbox lock code matches the K055 key, using the key is straightforward:
- Insert the Key: Gently insert the key into the lock cylinder. Do not force it. The key should slide in smoothly.
- Turn to Unlock/Lock: With the key fully inserted, turn it clockwise or counter-clockwise (depending on your lock mechanism) to engage the locking or unlocking action.
- Remove the Key: After locking or unlocking, return the key to its original insertion position before gently pulling it out.
4. Maintenance
To ensure the longevity and smooth operation of your replacement key and lock, consider the following maintenance tips:
- Keep Clean: Periodically wipe the key with a dry cloth to remove dirt or debris. Avoid using harsh chemicals.
- Lubrication: If the lock mechanism becomes stiff, apply a small amount of graphite lubricant or a silicone-based spray specifically designed for locks into the keyway. Avoid oil-based lubricants as they can attract dirt.
- Proper Storage: Store your key in a safe, dry place to prevent loss or damage.
- Avoid Force: Never force the key into the lock or apply excessive pressure when turning. This can bend or break the key, or damage the lock.

- Key Inserts but Does Not Turn:
