3. Finding Your Lock Code
To ensure you order the correct replacement key, it is crucial to accurately identify your lock code. The lock code is typically a combination of letters and numbers.
Here are common locations where you can find your lock code:
- On the Original Key: The code may be stamped directly onto the head or blade of your existing key (e.g., FR322).
- On the Lock Face: For some locks, the code is engraved or printed on the visible face of the lock cylinder (e.g., FR322).
- On a Label Inside/Behind the Lock: Check for a sticker or label located inside the toolbox or on the back of the lock mechanism itself (e.g., CODE: G38).
- On the Cabinet/Door Label: Some manufacturers place a label with the lock code on the cabinet or door where the lock is installed (e.g., HF321).
Important Notes:
- Order by Manufacturer: Lock codes are often manufacturer-specific. Always verify that your lock code and manufacturer match the product title and description.
- Key Cuts Differ: Even if codes appear similar, the actual key cuts can vary significantly between different brands.
4. Compatibility
This replacement key is compatible with the following manufacturers and key series:
- Manufacturer: ProTech
- Key Series: ProTech 501XT - 750XT
- Lock Code: 520XT

Ensure your existing lock code is 520XT and your lock is manufactured by ProTech for proper fit.
5. Usage
